Kommerling and G-Smatt Glass consolidate their relationship with a series of exploratory meetings wi

G-Smatt Glass, CEO Ho Joon Lee, was joined by Chris Davis of Kommerling for a series of high level meetings in the UK as G-Smatt starts to plan its move into the UK and wider European markets. The two companies have worked closely over the last few years to develop a ground breaking construction grade laminated glass with minute LEDs that bestows the glass with media functionality
“We have now successfully installed our product in over 50 different buildings in the Far East and Asia. It has been well received and is transforming buildings that were eyesores into destination city landmarks. With the continuing investment in new developments both in London and other major metropolitan centres we feel that it is the right time to start making the key players aware of this product’s potential. Not only does it deliver on all the construction criteria but it will enable the shell of a building to generate more profit for the developer if used correctly,” explained Ho Joon.
One of the organisations that was privy to a full presentation about the products capabilities was Eckersley O’Callaghan where more than a dozen engineers were able to see videos of existing installations and find out more about the possibilities offered by this construction grade glass, with benefits. “This glass will allow us as engineers to deliver buildings and facades that have a dynamic appeal. The impact that an installation of this type will have on the surrounding cityscape is hard to evaluate but there is the potential to put more traditional media displays and external lighting installations in the shade,” commented Sanmukh Bawa, engineer with the company. Other companies also showing an interest in the product include Arups, Hamilton-Erskine and ICON.
G-Smatt also have plans in place to open an office in Los Angeles later this summer to serve the American market.
The small LEDs are placed at regular intervals approx 40-90mm apart, depending on the specification and when viewed from the inside there is less than 0.3% reduction in visibility through the glass. This is considerably less than when one of the current alternatives such as an overlay or frame structure is used which can give the impression of being in a cage or prison cell when viewed by the building’s occupants. Even when illuminated at night people within the building will not be dazzled by reflection as less than 10% of the light emitted by the LED’s is reflected back into the building.
The science within the glass
Kommerling has worked closely with G-Smatt’s development team to make this innovative glass a commercial reality. The company’s R&D team in Pirmasens, Germany has developed a new formulation for the resin that is used to bond the two layers of glass around the encapsulated LEDs. There were several complex issues that had to be accommodated, namely:
– a passive curing profile was required to avoid high temperatures and pressures damaging the embedded LED and FPCB components.

– the resin had to be compatible with and not compromised by the presence of the adhesives used to secure the LEDs
– the conductive adhesive that fixes FPCBs onto the FTO coated glass would be dissolved by a traditional glazing sealant
and finally the resin had to have a similar refractive index as the glass and was required to cure without any bubbles, otherwise these would become greatly illuminated once the LEDs were lit on.

GGF RELEASE GLASS REPAIR TECHNICAL PUBLICATION

News, Politics, Technical News | 23.07.15

The publication covers the optical and quality factors that influences the appearance of glass following surface repair. The major emphasis of this new technical document is on the visual performance when glass is viewed from inside a building.

Bob Griffin of Re-newglass and Chairman of the GGF Glass Repair Group commented; “This will prove not only a highly useful data sheet but also a very important one for the sector. For some time there has been concern in the industry over glass polishing and in particular on toughened glass. This document answers those concerns.”

The Data Sheet addresses causes and types of glass surface and edge damage as well as optical and visual quality across many types of glass including annealed, toughened, laminated and coated glass. The publication then explains the repair process and method of assessment.

Bob added, “I am very pleased this publication has been released. It will provide vital information for customers and glass producers who are looking for guidance on treatment options for surface damage. It is the authoritative technical publication that should become a required industry reference for all looking to repair glass.”

Brian Baker of Glassolutions and GGF President is a Member of the Glass Repair Group and helped produce this latest document. Brian concluded, “It is yet another excellent addition to the GGF library of technical information and I have no doubt will be essential in guiding the industry when it comes to repairing glass surfaces.”

Non-Members can buy this new product direct from the GGF Shop here.

The Glass Repair Group is currently reviewing its online presence and is planning to create three new sections on the GGF Website in the autumn including; Industry Case Studies, Five Steps to Help Decide on Glass Repair and a list of Frequently Asked Questions (FAQs) on Glass Repair.

In addition, Chairman Bob Griffin will be presenting at GGF Members’ Day on 1^st September in London, where he will be highlighting the Group’s activity.

Energy Efficient Glazing: A Useful Guide

| 22.12.23

In any property heat will be lost through windows and doors, however this heat loss can be reduced when a home has energy efficient double or triple glazing.

Energy efficient glazing helps keep heat inside the home and, in combination with other home energy efficiency measures (such as cavity wall insulation, loft insulation and an energy-efficient heating system), can lead to a reduction in annual heating bills.

And that’s just the start. The benefits of having energy efficient glazing installed in your home can also include a reduced carbon footprint, improved home security and noise reduction.

If you’re considering investing in energy-efficient glazing, you’re certainly not alone. There’s a lot to gain from this home improvement, but of course there is also a lot to consider.

This short guide will take you through some key information that will help you make an informed decision.

What is energy efficient glazing?

Energy-efficient glazing is the term used to describe glazing consisting of two or more glass panes within a sealed unit. This includes double and triple glazed windows and similar units found within doors.

Energy-efficient windows and doors consist of a framing material (timber, aluminium, PVC-U or composite) into which one or more glass sealed units are fitted according to the style of the window or door.

Energy-efficient glazing is rated according to its ability to reduce the amount of heat that can pass through the window, the capacity for sunlight to travel through the glass unit, and the capacity for air to move through the unit.

Commonly, the highest-rated glazing according to efficiency is made with Low-Emissivity Glass which has a special coating on the inner surface of one pane, enabling light to travel through whilst reflecting heat back into the room.

What is in between the glass panes of a sealed unit?

The air gap limits the amount of cold air able to get into your home. It does this by acting as an insulator and is completely sealed.

The space between the glass panes is filled with air or gas such as argon, krypton or xenon. These help reduce heat loss through the unit. When gas such as argon – which has low conductivity – is used within this space, the window is then even more efficient at keeping heat inside the property and also at interfering with sound waves from inside or outside the house, reducing noise pollution.

Sealed units also have a strip in between the panes, made from metal or polymer. This strip is called a spacer which can contain a drying agent that deals with any moisture that is trapped in the space between the sheets of glass.

The type of frame material used

As with the glass itself, the frame material used in energy-efficient windows and doors is also important.

There are several options here:

PVC-U has many benefits including performance longevity (usually 20 years or more) and is recyclable.

Wooden frames are environmentally friendly and are often specified for properties where the use of original materials is necessary, such as those within a conservation area.

Aluminium frames are an eco-friendly, modern choice because the creation of the material is low impact, recyclable and the slim look of the frames is desirable.

Composite frames are composed of a combination of wood and aluminium or plastic.

Energy rating and u-values

For ease of purchase, certain window manufacturers label the energy efficiency of their windows with an energy rating ranging from A++ to C, A++ being the most efficient. This rating system has been developed by the British Fenestration Rating Council (BFRC) and it takes into consideration the entire window.

When this energy rating is given, a whole window u-value is also calculated. The u-value refers to how easily heat can pass through the unit. The u-value scale works in the opposite way to an energy rating, in that the higher the u-value, the more easily heat can pass through the window and the window is less efficient.

The benefits of energy-efficient glazing

There are many benefits of EEG, which are increasing all the time as technology and building techniques advance, and our eco-awareness increases.

Key benefits include:

Improved energy efficiency: Energy-efficient glazing may form part of a wider range of energy-saving measures. If your home also contains cavity wall insulation, loft insulation and an energy-efficient heating system, these can all work together to reduce the amount of energy needed to heat your home. As a consequence, you can enjoy lower energy bills and a reduced carbon footprint.

Reduced noise pollution: Sealed double and triple glazing can be effective at reducing medium to high-frequency noise, creating a more comfortable, private and peaceful home environment.

See more: Glazing and noise reduction in homes

Improved thermal insulation: Energy efficient glazing can help to keep your home warmer in winter and cooler in summer. The air or gas gap between the panes of glass in a sealed unit provides an extra layer of insulation. This increased thermal resistance reduces the amount of heat that can escape the home during the colder months. In summer the reverse occurs, and the windows help keep the heat outside, keeping the home cooler.

Reduced condensation: Energy efficient windows and doors help reduce the risk of condensation which occurs when a cold surface and moist air meet. The resulting moisture can potentially damage the window frame and if it is particularly bad, may even affect other areas of the room.

See more: How double or triple glazing helps reduce condensation

Safety and security: As there are two or more panes instead of one, energy-efficient glazed windows offer a more secure barrier against unwanted entry than a single glazed window. The level of security can be enhanced further when laminated glass is used.

Cost savings: Assuming all other measures have been taken, Installing energy-efficient windows can save you money over the long term by reducing the amount of energy required to heat your home.The savings you gain from energy-efficient glazing will depend on a number of factors, including the size of the home, the type of windows you purchase and your energy supplier. For an indication of the potential savings, you could enjoy based on your home and windows.

A more comfortable living environment: Lower heat loss, plus reduced noise, helps toward a feeling of a much more comfortable home.

Increased home value: Making energy-saving improvements to your home has the potential to boost its value. Potential homebuyers are increasingly aware of the eco-credentials of any house they consider purchasing. According to a report conducted by the Government based on property sales made between 1995 and 2011, a homeowner making energy-saving improvements to their home could see a 14-38% increase in value as a result.

A note on the importance of ventilation

In newer dwellings with higher-efficiency insulation, a lack of adequate ventilation can increase the risk of condensation forming on internal surfaces – including on windows and other glazed surfaces. A way of reducing this risk is to ensure each room has adequate ventilation, such as trickle ventilators or other forms of ventilation.

Continuous improvements in frames, glass and gas combinations mean the consumer’s energy-efficient window choice is increasing all the time. Energy-efficient glazing is a beneficial addition to any modern

Glazing and noise reduction in homes

| 22.12.23

Replacing or upgrading your windows can improve noise reduction in the home.

What is noise?

Noise is unwanted sound. In the home, this is any sound that distracts or disturbs the occupants.

This could be anything from nearby traffic or low flying aircraft to sounds coming from neighbouring properties such as music and loud conversation.

How it travels

Sound travels through the air (and solids and liquids) like the ripples seen on the surface of a pond when you throw a stone into it. Just like these ripples, the waves decrease in intensity as they move away from the source.

Sound intensity is measured in decibels (dB). A low dB value indicates a soft sound and a high dB value a loud sound.

How it affects us

The perception of noise will vary from person to person depending upon the source of the noise and the individual’s tolerance/acceptance of a given type of noise.

For example, a person living next to a busy road for a number of years may have become accustomed to it, whereas someone relocating from a quiet location to the same busy road may find the noise a nuisance.

How glazing can help reduce noise

One of the many potential benefits of replacing windows or installing secondary glazing in your home is that in doing so you can often also improve your property’s noise insulation.

The correct installation of good quality, well-made windows or secondary glazing systems can result in a noticeable reduction in noise levels.

Type of glass

The type of glass used within your replacement window could have an effect on the level of noise reduction. Glass is available in a range of thicknesses and typically thicker glasses reduce more noise.

Domestic windows usually use 4mm-6mm thick glass. Some window panes are made up of two or more pieces of glass that have been bonded together; these are known as laminates. Specialist, acoustic laminated glass is available from many glass manufacturers.

Thickness of glass

Different thicknesses of glass are effective at reducing noise at different frequencies. As a result, a sealed double or triple glazed unit with glass panes of different thicknesses (i.e. both 4mm and 6mm) will be effective at reducing noise across a wider range of frequencies than if both panes of glass were the same thickness.

Triple glazing

In addition to reduced thermal losses, triple glazed units can provide a reduction in noise. By increasing the combined thickness of the glass within the unit, the mass is increased. A reduction in noise transmission will result from this additional mass.

Air gap

The size of the air gap between the panes of glass in either a double or triple glazed window or a secondary glazing system makes a significant difference to the level of noise insulation. Typically a large air gap will improve noise insulation.

Secondary glazing

Secondary glazing is when another window or glazed screen is positioned within the window reveal of an existing window.

The extra glass pane and air gap now present in the window unit help to improve its noise insulation properties. In some cases, noise reduction can be further improved by lining the window reveal with sound insulation material.

The effect of ventilation and air gaps on noise reduction

To be effective in reducing noise new windows and secondary glazing systems must be fitted and sealed correctly. Any air gaps around your window will seriously affect its noise reduction properties.

It is also important that any opening window can be securely closed with a good quality seal. If the window does not close correctly noise will be able to infiltrate the property.

Bear in mind that many windows are designed to provide your property with a means of ventilation. Background ventilation through trickle ventilators can, if left in the open position, provide a passage for sound to travel.

Likewise, an open window, perhaps in the night lock position, will not aid sound reduction.

Glazing may only be part of the solution

Replacing or upgrading the glazed elements of a home may not singlehandedly solve the problem of excessive noise levels.

This is because noise entering the home via roofs, walls and floors will not be reduced as a result of changes to glazing. Depending upon the source of the noise and type of property, replacing or upgrading the glazing may only be part of the solution.

It is important to discuss your requirements and your expectations with the window installation company.

By explaining the source of noise that you are trying to reduce, the glazing company can advise you on what can be achieved.

The dB reductions possible using the various methods can be supplied by your glazing contractor. Any claim of noise reduction should be backed up by test evidence.

GGF Members will be able to advise you on the most suitable glazing option to reduce noise in your home – find a local GGF Member company.

Planning a conservatory – things to consider

| 22.12.23

Planning your conservatory

With a wide range of conservatory types available, careful thought and planning can help you decide on the one that fits best with your home and suits the needs of everyone who will be using it.

Once you’ve chosen a conservatory style, here are some more things to consider when planning your glazed home extension.

Size

When deciding on the size of your new conservatory, make sure you’ll have enough space to enjoy it. A handy tip is to mark out the planned dimensions in your living room so you can see how much furniture you’ll be able to fit.

Sunlight

How much direct sunlight will your conservatory receive and at what time of the day? This could have a bearing on your choice of building location and also interior design decisions.

The orientation of your conservatory may mean that certain specifications of glazing are more appropriate than others because of the impact of solar heat gain from the sun (see ‘Glazing’ below).

Materials – general

You can choose from a wide range of materials for your conservatory, not only for the frames but also in the glazing, the roof and any masonry.

Think about the mood and texture you want to achieve. Some people like the ‘outdoor’ feel with tiled floors, patio-type furniture and bare brick or stone for the house wall; others prefer an ‘indoor’ character with carpeting, soft furnishings and wall coverings.

Materials – frame

Aluminium, with thermal breaks for enhanced heat insulation, is a popular choice and is available in a range of colours and finishes.

PVC-U is the most popular frame material with its long life expectancy and minimal maintenance, especially as nowadays a range of wood grain-effect finishes combine the authentic look of wood with all the toughness of PVC-U.

Wood is the natural choice for people who insist on the real thing.

Glazing

Double glazing is a must nowadays to keep a conservatory comfortable all year round and by using low emissivity (Low-E) glass, it can cut heat loss even more.

If the conservatory is south or west facing it is advisable to consider the use of a modern solar control glass for the roof and side panels of the conservatory.

Solar control options range from ‘body tinted’ glass (where the colour in the glass absorbs heat from the sun) to ‘metallic coated’ glass products.

Modern metallic coated products have the advantage of being neutral in appearance, not obscuring views, while still reflecting the sun’s heat.

Roofing

There are two main choices of roofing – glass or polycarbonate.

Glass gives you a clear view through the roof – it can be supplied with solar control and self-cleaning coatings too. Laminated glass and safety filmed glass can add protection you from any falling debris on the roof glazing of your conservatory.

Polycarbonate creates a softer light effect in bright sun (however, it is slightly noisier in heavy rain or hail).

Ventilation

Ventilation is important. You need to be sure that your conservatory will let in fresh air and avoid condensation.

The internal environment can be carefully controlled with the correct specification of both materials and ventilation. Many roofs have built-in trickle ventilation and Building Regulations specify a certain area of opening windows per floor area.

Technological developments mean that you can have opening roof vents installed that can be thermostatically controlled with built-in rain sensors.

Sound control

Whether it be rain, music, lawn mower, traffic or aircraft noise, reducing the impact of environmental sound can enhance the enjoyment of your conservatory.

The use of laminated glass or enhanced acoustic insulation laminated glass can lessen the amount of noise transferring into or out of your conservatory.

In addition, laminated or acoustic laminated glasses have the extra benefit of reducing standard ultra-violet (UV) light transmission. This means sun bleaching of furniture or fittings is dramatically slowed.

Cleaning and maintenance

Consider what will be required to clean and maintain the glass throughout your conservatory.

Surface modified glass such as self-cleaning glass is available from many glazing companies and can reduce the need for cleaning the external window panes, particularly in difficult-to-reach roof areas.

Comfort and convenience

Comfort levels and environmental factors should be considered. You may wish to extend your home’s central heating, install a separate heater or go for an underfloor heating system, but remember careful specification, design of materials and the location of the conservatory itself can all lead to natural environmental control.

Similarly, you can have overhead wiring for lights built-in or simply a few wall sockets for a table lamp and other appliances.

For more advice on choosing the right conservatory for your needs, get in touch with a local GGF Member company.

Revised Datasheet on IGU visual quality

Uncategorized | 27.08.21

The GGF is pleased to announce the launch of the revised GGF Datasheet 4.10, Appearance and Visual Quality for Insulating Glass Units (IGUs).

Data Sheet 4.10 details all of the appropriate optical and visual quality factors of the glasses used to manufacture the IGU, that influence the appearance of an installed IGU.

The most important criteria is the view through the IGU from the inside of a building, which is covered in detail. However, it is appreciated that the appearance from the outside of the building (i.e. in reflection) can also be important in certain applications and Data Sheet 4.10 also makes reference to this.

The origins of glass visual quality standards and why GGF Data Sheet 4.10 is the go-to document:

The standard for float glass in Europe in EN 572 Glass in Building – Basic soda lime silicate glass products. Part 2 defines optical and visual faults and the relevant acceptance levels. The viewing distance for standard float glass is 4.5 metres.

A glass manufacturing float line typically produces around 700 tonnes per day. The raw materials are mixed and melted down at high temperatures within a refractory lined furnace. The molten raw materials are then floated on a bath of tin and moved through the float line to create a continuous ribbon of glass.

Most glass installed within buildings is manufactured from float glass in accordance with EN 572. In many installations the glass requires additional processing to provide the correct performance in terms of safety, security, and energy requirements.

Glass can then be coated to provide a specified level of solar control or thermal insulation, screen printed, coated with ceramic frit or the surface altered, to provide decoration or privacy.

In addition to this the glass may undergo a heat treatment processes to add certain characteristics. It can be thermally toughened for increased strength and safe fracture behaviour, heat strengthened for additional strength, heat soaked to reduce the risk of spontaneous breakage when installed on site, or laminated for safety, sound attenuation and security.

All of these additional processes involve changes to the original float glass product and usually results in varying amounts of alteration in the visual quality and appearance of the products. The visual quality rules in EN 572 are no longer applicable so we need to look elsewhere.

For Thermally Toughened Glass manufactured in accordance with EN 12150, the standard does not contain any visual quality limits but does stipulate that visual inspection should be included during the manufacturing process. However, the standard does mention the existence of roller wave, pitting and anisotropy, but does not define any limits regarding these characteristics. This is the same for Heat-Soaked Glass Manufactured in accordance with EN 14179.

For laminated glass the standard is EN ISO 12543 Glass in Building – Parts 1 to 6. Part 6 details the appearance and defines vents, creases and streaks, spots and linear defects and the levels of acceptance. The glass is visually inspected at 2 metres under normal daylight conditions.

Coated Glass in accordance with EN 1096 defines uniformity, stains, spots, pinholes and scratch faults and the acceptance levels. The glass is viewed from a minimum distance of 3 metres for no more than 20 seconds.

Heat Strengthened Glass in accordance with EN 1863 states that the processor is responsible for determining the visual quality standards to be used for their products. However similarly to EN 12150 and EN 14179, the standard does mention the existence of roller wave and anisotropy but does not define any limits regarding these characteristics.

As you can see depending on the products used, negotiating visual quality may not be as straight forward as it may first seem. This is where GGF Data Sheet 4.10 steps into a very important void. It covers all of the above-mentioned products, as well as visual phenomena’s that may be encountered with flat glass products. It is the only recognised visual quality standard within the UK for visual quality of installed insulated glass units. It is also widely used across Europe and the Middle and Far East. This mean 4.10 is one of our most important Data Sheets.

4.10 has been updated to incorporate the latest changes within BS, EN & ISO Standards so GGF members can continue to be the leading experts within the industry. The Consumer facing visual quality leaflets are also due to be updated in 2021.

The Data Sheet can be downloaded from the members area of the website within the glazing manual. Click here to access

The homeowner’s guide to buying and installing bi-folding sliding doors

| 19.08.21

Bi-folding sliding doors seamlessly bring outdoor and indoor space together. In addition to increasing living space, bi-folding doors can increase natural light and ventilation, while aesthetically improving and increasing the value of your home, plus your lifestyle.

When it comes to planning which bi-folding doors are right for you, it’s important to do your research as they’re available in many different styles, finishes and materials. Important considerations when selecting your bi-folding doors include:

1. Selecting your bi-folding sliding door type

With top-hung style, the overhead operations are easier to conceal and it’s less likely to jam due to grit in the operating mechanism. However, this does require a strong lintel/beam to take the weight of the doors. While with bottom rolling design there’s less weight on the frames, but the sliding motion can be affected if grit gets into the tracks/rollers.

2. Types of framing materials

The types of framing materials include:

Aluminium is easy to maintain, it has a powder-coated finish with multiple colour options and no painting is required. It can be wider than timber (meaning fewer doors are required) and it’s lightweight

Timber is a classic option for a traditional/period home. However, some lower-end timber models may be prone to warping when exposed to heat and moisture, meaning it could get stuck in the tracking or not close. Timber also requires regular painting/varnishing to maintain its appearance

Composite doors consist of aluminium frames with timber internal facings, offering the best of both materials

UPVC is less expensive, low maintenance and has good thermal performance, while the frame finish can include multiple colour options. However, size ranges are limited

3. Glass types

Triple or double glazed is a must, as the right glass choice/configuration can improve thermal efficiency and also reduce unwanted noise. These also offer safety and security, as both toughened and laminated glass can offer you reassurance and protection.

4. Other tips

Plan a master door that will be used most often and think about thresholds. A low threshold provides a seamless look into the outside space with little or no step, whereas a rebated threshold offers increased weather-resistant performance.

5. Installation

Use a GGF member company and get peace of mind that you are getting a quality product and professional installation from a company supported by the main trade authority in the sector.

If you’re planning on installing bi-folding sliding doors, here are some more helpful tips.

Coping with the Supply Chain Issues

News, Technical News | 25.06.21

GGF Senior Technical Officer, Ben Wallace provides an update on the challenges facing companies in the glass and glazing supply chain and puts forward some recommendations for GGF Members in order to cope with the current issues.

As the toll on human health from the spread of Covid-19 is evaluated, the economic effects of the crisis and the livelihoods at stake are also coming to light. At the GGF we are hearing of extensive delays within the supply-chain of the glass and glazing industry, and throughout the construction industry as a whole. GGF Members must respond on multiple fronts at once, at the same time that they work to protect their workers safety, they must also safeguard their operational viability now increasingly under strain from a supply-chain shock.

As well as Covid-19, other factors have led to disruptions causing the slowing of the construction supply-chain, including; container shortages, factory fires and the recent blocking of the Suez Canal. This has already led to the current global shortage of many materials used within our industry, and more recently the supply disruption of another critical category of materials is occurring – plastics. Constraints on the supplies of their raw materials, especially polyethylene (PE), polypropylene (PP), and monoethylene (MEG) are leading to factory shutdowns, sharp price increases and production delays across the construction sector. It is not un-realistic to believe that this will have a knock on effect for both Un-plasticised Poly Vinyl Chloride (UPVC) and Poly Vinyl Chloride (PVC).

With two float lines down at major glass manufacturers and interlayer shortages, especially with Polyvinyl Butyral (PvB), laminated glass supply is being allocated. We are also receiving reports of extensive delays throughout IGU production. It is important to understand that there are underlying uncertainties in the forecast for both the short and medium term.

We recommend that GGF members should:

Create a clear plan throughout supply chains, establishing a list of critical components, determining the origin of supply and identifying alternative sources. As we open up a global UK we have an opportunity to identify new supply chains from alternate global regions.

Estimate available inventory along the chain for use as a bridge to keep production running and enable delivery to customers. It’s now more important to test the resilience of material supply chain through business continuity scenario planning.

Assess realistic customer demand for both the short and medium term and ensure you manage your customers’ expectations.

Optimise production and distribution capacity to ensure employee safety and engaging with teams to share infection risk levels and work from home options. These steps will enable managers to understand current and projected capacity levels in both workforce and materials.

Understanding where supply-chain issues will start to cause a financial impact and protecting your company against future supply-chain price increases.

With the positive news that the glass and glazing sector has bounced back relatively quickly under difficult circumstances, and homeowners are continuing to invest into their properties, it is important that members formulate a strategy to balance demand against a slower supply chain. Members should note that lead time extensions and price fluctuations may be factor throughout the second half of 2021 and into 2022.

With this is mind, management of demand and lead times is essential and consumer facing members need to make their customers aware of potential delays. Dates and prices agreed with homeowners must be achievable.

On a positive note, with the heightened supply chain awareness and knowledge Covid-19 has brought, it will better our position to continue managing our industry through any future challenges that may emerge.

New Technical Homepage

Glassi | 06.04.21

This month sees the launch of the new Technical Homepage on the GGF website.

As well as an obvious re-design, the aim of the new Homepage is to provide a more informative service primarily for GGF Members but also to show non-Members and the wider industry such as architects, specifiers and building designers, the many technical services the GGF offers.

David Borland, Senior Technical Officer explains;

“Rather than provide a generic who we are page, we wanted to provide up-to-date information on matters which are relevant to our members and give them a more immersive experience.”

The concertina style drop down design has multiple sub-sections for the user’s convenience and ease of navigation.

A visit to the Technical Homepage shows sections such as Latest News and Events which provides details of upcoming events such as webinars and technical forums. Each topic providing links to relevant documents or booking forms.

The Latest News and Events sub-section will also include recent events such as the two Technical Forums; the “Ban on Laminated Glass for facades and balconies” and “The Future Homes Consultation” with full video coverage and documentation links.

The new Technical Homepage will also house relevant information and links to Government and trade information that may impact on Members’ business.

The Consultation sub-section contains details and links to all current Consultation documents and covers both the UK and ROI. Some of these consultation will also link to webinars in the Events section if relevant.

A complete list of industry standards from BSI (UK standards), CEN (European standards) & ISO (international standards) that are currently under review, shows the current status of each standard and relevant dates for response to the relevant standards body (BSI, CEN or ISO).

Members can also find, view and download the most GGF Technical Report on the Technical Homepage. The information is presented in such a way that Members can either downloaded from the page in either full typed form or as a PDF copy of the Meeting presentation.

David Borland concluded, “We very much see this a stepping stone to providing an interactive and informative source of important information for our Members and are keen to receive feedback on how they believe it can be further improved. In the meantime, I am sure that Members will find the experience of finding GGF technical documents and information far easier than ever before.”

Glassi, News | 06.04.21

Welcome to the spring issue of GLASSi.

Firstly, I express my sincere condolences to the family and friends of Stephen Byers, who sadly passed away a few weeks ago. I knew Stephen very well and shared many GGF meetings and social occasions with both Stephen and his wife Karen. In this issue of GLASSi, we pay full tribute to Stephen, who was a very popular and respected GGF Member for over three decades. He will be sorely missed.

As we enter the new season, we sincerely hope that the UK is on the road to recovery from the huge disruption and restrictions caused by the COVID-19 pandemic.

Over the last 12 months, the future has at times looked very bleak for business and society as a whole. The future though is now looking a lot brighter with the Government’s roadmap to recovery, the easing of restrictions combined with the success of the Government vaccination programme. This is as result of the rates of infection, cases and fatalities decreasing.

As the situation has evolved the GGF has worked closely with Governments, local authority partnerships and health and safety experts to ensure you receive the latest information and guidance. We will continue to work with all the relevant bodies to ensure you and your staff are protected with the most up to date and best possible guidance.

Though there is much optimism, there is still no room for complacency and we should all continue to follow the guidance, protect the NHS and save lives.

Brexit

Since the last edition of GLASSi, the transition period for the UK to leave the EU ended on 31^st December 2020.

With the UK no longer being part of the EU, there have been and still are difficulties for companies who import and export. Members have reported problems with administration at customs, delays in transportation, price increases in haulage generally and containers specifically. In addition, the industry has also seen a change to the regulations around CE Marking and the UK has now introduced a new UKCA Marking system which all companies will have to adhere to if their products fall within scope of the Construction Products Regulation. The GGF Technical Team are working with MHCLG (Government Ministry of Housing, Communities and Local Government) and our fellow Trade Associations in making representations on behalf of members to try and make this process as straightforward as possible for companies who place products (within scope) on the market.

In this issue of GLASSi, David Borland, GGF Senior Technical Officer has produced an update on the current status regarding CE Marking and UKCA Marking.

Energy Efficiency

The Government recently announced that the Green Homes Grant Scheme launched last September has been cancelled. Since the launch of the scheme (which did not consult with huge parts of the construction and glass & glazing sector in advance of its launch), the GGF raised concerns to Government over the restrictive PAS 2030 accreditation gateway to becoming an approved installer to carry out measures and also the glazing element of the scheme which only allowed for single glazing to be replaced as a secondary measure. The GGF also made representations to Government that Competent Person Schemes should be used as an alternative or complimentary to PAS2030.

Though this scheme hasn’t worked for our industry, the GGF is continuing talks with Government over future schemes that will hopefully have more emphasis on glazing.

GGF Products and Services

In the first quarter of 2021, the GGF team have been extremely productive to increase and improve your benefits.

On the health and safety side, we have launched the new Health and Safety Webinar Programme which is freely available for all Members to attend. The next webinar is on “Managing Mental Health during COVID-19” and is on April 6^th. You can book your place at this webinar here.

The GGF Digital Marketing Toolkit was launched recently and includes free access to 12 video webinars accompanied by PDF presentation files for free download. The digital marketing toolkit has a content value of over £1k, so I encourage all Members to take full advantage to grow their online audience, customers and business using digital technology.

Also on the marketing and PR front, the GGF is continuing its consumer campaign Stay Safe with MyGlazing.com following the success of the campaign in 2020 when over 200k consumers looking for advice through the pandemic visited the MyGlazing.com website for advice. The campaign was also publicised in over 100 consumer publications reaching millions of homeowners.

The GGF Technical team in that last 12 months has published 42 new technical publications and is continuing up review and update a further 26 as part of the ongoing technical documentation review process. In addition, the Team organised two exclusive Technical Forums in February and it was great to see over 100 GGF Members attend via video link, “The Ban on Laminated Glass in Facades and Balconies Forum” and then just a few days later attend the “Forum on the Government’s Future Homes Consultation” which will impact the Building Regulations approved documents L (energy efficiency) and F (ventilation).

Members Meetings

In the first few months of the year we have already seen an increase in Members meetings and particularly in the Regional meetings, Window Film Group and Heritage Window Group. With Member engagement increasing via video meetings, we are looking at returning to face to face meetings once the lockdown restrictions allow such gatherings. We will of course keep you updated on when this will happen and rest assured we will also be continuing with the video conferencing as well as face to face meetings, to enable all Members to engage regardless of distance and time.

An up to date list of GGF Members Meetings for 2021 can be see here. Please feel free to contact the assigned GGF Secretary if you want to find out more about our meetings and/or if you wish to attend any of the Members Regional or Technical meetings.

Finally, I was delighted to see all parts of the GGF membership represented at the Chairperson’s Forum (held on 18^th March). With 33 Chairs/Representatives at the Forum it was an exceptional attendance and many of the points raised by Members have been fully taken on board and will be address by the GGF Board and Staff. A full report of this meeting will be issued to all who attended to cascade to all Members.

We look forward to working on your behalf to help your business through these trying times.

Enjoy GLASSi

Tech Talk

Glassi | 18.12.20

2020 in Review

In this special feature, David Borland, GGF Senior Technical Officer provides a review of the GGF Technical Department’s progress in the last 12 months.

The Technical Department has seen a lot of changes in 2020. As we said a fond farewell to two GGF technical stalwarts in Steve Rice and Russell Day, off to enjoy his retirement and to pastures new respectively, in spring, we welcomed two new Technical Officers, Steve Chappell and Kevin Jones.

Both Steve and Kevin bring a wealth of experience in the glass and fenestration sectors. Regular attendees to our Technical and Regional Groups’ meetings will already be familiar with both technical officers and though there have been no face -to face meetings due to the pandemic, Members who have attended technical meetings this year should already have a clear understanding on what both Steve and Kevin will bring to the GGF Technical Department.

After a short hiatus in early 2020, our regular Technical meetings were re-instated in late April, albeit through video conferencing. A medium with which more and more Members are becoming familiar with and we will continue to use this channel post pandemic when we hope to resume face to face meetings. By doing physical meetings that simultaneously incorporate video as an option, all Members will have the opportunity to attend wherever their location.

Throughout 2020 we have continued to argue the case for laminated glass’ removal from the MHCLG (Ministry of Housing, Communities and Local Government) Combustible Materials Ban and this month sees the presentation to MHCLG of a 94-page technical document providing evidence and test results to justify its removal. We will keep members updated on how this is received and hopefully see a positive outcome for the industry with a balanced and common sense decision.

Back in January and as a result of the Future Homes Forum held for Members in Solihull, we responded to both England’s Part L & F and the Welsh equivalent. As of today, we still await the outcome of these. November saw the introduction of the Welsh Consultation document for Part L & F -Existing dwellings & Commercial Buildings. After we have completed our own review, we may hold another Members’ only Technical Forum early in 2021 by Video.

Since March, the Technical Department has also created and/or updated 19 Datasheets and this will reach a total of 30 Datasheets by early 2021. These covered a wide variety of topics with some being particularly overdue for update. We’d like to thank the Members who contributed and assisted in making this considerable achievement possible. Staying on the subject of Datasheets, in October 2020, the GGF introduced a Document Review Page on the Members’ Area of the GGF website. This new section now allows members to review, comment and contribute to new Datasheets and technical documents on an on-going basis.

We continually strive to improve the service to our Members and have made several changes over this year. Our Technical Inbox prioritises our Members with the aim to provide same day/next day replies to Members’ technical enquiries. In addition, mobile numbers for all Technical Officers are available to view on the GGF website for quicker and more direct response. Starting 4^th January 2021, we will also introduce a new Technical Hotline, which will ring through to all Technical Officers simultaneously and answered by the first available Technical Officer. These procedures are in place to help Members make contact with and use the GGF’s technical resource to benefit their business.

One of the year’s highlights for the GGF Technical Department was the organisation and hosting of the GGF Technical Forum and Technical Presentations via Video link to the Membership during Members’ Week. This was positively received by all who attended and I would like to take this opportunity to thank our guest speakers Mark Barsby of BSI, and Sanmukh Bawa of G-SMATT Europe for sharing their expertise and perspectives.

Whilst we certainly see 2021 as another challenging year, be assured that the GGF Technical team will continue to develop and improve the service provided to our Members. On behalf of the Technical Team, I wish all Members the very best for the festive break and we look forward to working with you in what will hopefully be a healthier and prosperous New Year.

Fire Safety: Approved Document B

On Thursday 2^nd April the Document B (Fire Safety) Working Group held a remote meeting to respond to the ‘Review of the ban on the use of combustible materials in and on the external walls of buildings including attachments – A technical consultation paper’

The deadline for this response to the Government Ministry of Housing Communities and Local Government (MHCLG) is 13^th April 2020.

Ben Wallace, GGF Senior Technical Officer hosted the meeting and commented, “This consultation is very important for laminated glass being used in balconies. We need the MHCLG to review, as laminated glass is currently not within the specification for buildings over 11m in height. It is crucial that the GGF takes a leading role in additional research into Laminated Glass for the benefit of our Members. We will share the final response with Members and keep them up to date with the outcomes.”

Technical Consultancy

The GGF technical advice and guidance is continuing but due to COVID-19 the GGF’s face to face consultancy services have been temporarily suspended. These include; site visits, inspections and the GGF’s expert witness service.

David Borland, GGF Senior Technical Officer commented, “The GGF Technical team has been forced to work from home due to the COVID-19 crisis. We will still be available to help Members via telephone or through email enquiries and we will be pleased to help anyway way can. We also advise all Members to follow the Government guidance keep well & stay safe and we look forward to meeting up with you after this crisis is over.”

A Successful Partnership

Glassi | 03.04.20

Gaby Mendham, Director of Ecoglass and Glass & Glazing Federation board member, discusses her recent partnership with Amplifi Solutions, a leading R&D tax credit specialist.

As Ecoglass’s joint Managing Director, I lead our business strategy and work with a range of customers across the UK. We are a Norwich based insulating glass manufacturer, toughened and laminated glass processor. Established in 1947, with over 70 years of experience, we’ve seen the countless benefits that innovation can bring to the glass industry. Research and development is part and parcel of our business model and investing in state-of-the-art machinery mean we can utilize the latest glass technology to bring our customers the very best quality products.

All this innovation has meant that we’ve been able to partner with Amplifi Solutions to secure a successful R&D tax credit claim.

As a member of the Glass & Glazing Federation, we heard about Amplifi Solutions through the association. They were extremely straightforward to work with, including their Managing Partners Chris and Jeff – who we worked with directly. R&D tax credits can seem like a bit of a red-tape minefield at first, but Amplifi Solutions really broke it down for us. It was an incredibly smooth process that was completed to our tight deadline.

We ran two recent innovative projects that made up our R&D claim. In one instance, we set out to improve the flexibility and responsiveness of how our existing software system by Clear Thinking – created and communicated information within Ecoglass. We explored new customisable tools and created bespoke connections back to our existing software, which has enabled us to have a truly in-depth vision and excellent control throughout all the manufacturing processes.

As part of a separate project, it’s very important to our ethos that we lead innovation. With ever-improving U-values and finer glass coatings to radically improve energy efficiency, we are creating bespoke online inspection to ensure we can immediately locate unacceptable defects quickly, which are flagged up by our Viprotron scanning system, prior to unit assembly.

After a lot of experimenting, we created a bespoke visual inspection unit prototype, which we are currently perfecting before fabricating it into a full production inspection unit.

Amplifi Solutions helped us to realise that both these projects were great examples of R&D and qualified for the scheme.

Now that I’ve seen what partnering with Amplifi Solutions can mean to our business, I’d thoroughly recommend getting in touch with them – I only wish I’d done it sooner! As our claim was our first, we could claim for two financial years’ worth on qualifying R&D spend and saw a substantial reduction in our corporation tax liability.

GGF Members can avail of expert R&D tax credit advice from Amplifi Solutions and benefit from a discounted entry rate on their fees.

For more information visit www.amplifi.solutions or call 028 9008 0125.

TECH talk

Glassi | 17.06.19

Steve Rice, GGF Director of Technical Affairs provides an update on the key activities of the GGF Technical Team in the first four months of 2019

It’s been an interesting start to 2019 for the GGF Technical department for presentations and training days for Members operating in the Fire Resistant Glazing sector as well as an architectural glazing conference in the GGF MENA Region.

Since the Grenfell tragedy and resulting inquiry by Dame Judith Hackitt, the GGF has been actively involved with the various Government meetings, industry work streams and consultations. However, rather than just offering our expertise, we are also actively delivering information and sharing practical knowledge with Members and the wider industry on the importance of fire safety.

Adrian Blaydon, GGF Technical Officer and Secretary of the Fire Resistant Glazing Group has been leading GGF Training courses on the subject. Adrian is also set to deliver fire safety presentations at the FIT Show and at FIREX International at London’s ExCeL
in June, where the GGF is planning a significant technical presence. If you need any training or wish to attend these seminars please feel free to contact the technical department directly: technical@ggf.org.uk.

In March, the GGF organised and hosted The International Architectural Glass Conference in Dubai in conjunction with the GGF MENA (Middle East and North Africa) Region. The conference was attended by over 100 delegates from glass companies from all over the world.

With an impressive line-up of speakers from the following seven technical experts from companies; Saint-Gobain, Filmtek, Kuraray, Gulf Glass, Emirates Glass, Momentive and the GGF, the following topics were covered:

• Grenfell tower fire and its impact on industry standards
• Sealant compatibility
• The performance of laminated glass • The anisotropy of glass
• Security glazing
• Acoustic glazing
• Adhesive backed polymeric

The conference was very well attended and the presentations expertly delivered. As with most industry events and GGF Members meetings with a technical element, the GGF technical team contribution was well received.

As well as supporting and informing Members in the MENA Region and internationally, our activity overseas also expands our technical knowledge and expertise as we compare and consider international technical standards against European and British Standards.

We can then cascade this knowledge to all Members via technical meetings or in our publications.

Working with Members, the GGF technical team can show the industry that we are second to none when it comes to technical expertise across all sectors in the industry.

STAY SECURED BY DESIGN WITH CENSOLUTIONS

News | 24.05.18

CENSolutions celebrates 10 years in business this year, and while they are widely recognised as the leading consultancy and test facility for the window, door and glazing industries, they have no desire to rest on their laurels.

. Instead the company is continuously extending its scope. One of the things they are increasingly asked about is the recently amended PAS24:12 regulations and how companies can comply in order to keep selling Secured by Design.

Wayne Rogerson, Joint Managing Director explains: “PAS24:12 came into effect in September 2013, so if you wish to continue selling Secured by Design to the consumer, you should already be up to speed. The standard calls for all glazed doors and windows which have a non-locking handle to have at least one leaf of glass that achieves a P1A classification. Our research has found that this glass needs to be at least 6.8mm laminated. With regards to P1A, this is a classification within EN 356:200 for a drop height of 1500mm. In fairness 6.8mm laminated achieves P2A, which is a drop height of 3000mm, sadly there is no classification for 6.4mm laminated: It is classed as a safety glass.

“There was a great deal of confusion since the changes were announced and judging by the enquiries we have experienced, this is still the case nine months later. We appreciate that changing standards can be confusing, but compliance will make the difference between being able to use Secured by Design in your marketing or not. By checking that your supply chain is offering 6.8mm laminated glass as standard, you can make sure that you are covered.”

As a supplier, Decorative Door Products by RegaLead was one of the first to take advantage of CENSolutions’ expertise to ensure their customers were prepared for the changes in good time for the deadline. Guy Hubble, Joint Managing Director explains: “As a specialist in a niche sector of the market we strive to lead the way in advancing specification within it. We have been offering 6.8mm as standard on laminates certified to P1A since August last year. As an integral part of the supply chain, it’s important to us to understand the changing legislation to ensure the correct specification of units to our customers. CENSolutions has played a key role, providing invaluable advice and guidance at every step.”

The GGF Glossary

Uncategorized | 23.01.17

The Glass and Glazing Industry has thousands of products and components as well as companies. Due to its size and diverse nature, it’s also full of jargon and terminology that quite often varies from region to region, country to country, sector to sector and even in some companies from colleague to colleague.

The GGF Glossary is here to help anyone who needs help in understanding it all. It is by no means exhaustive and the GGF is aiming to update this page regularly. If you have and addition or feel something is missing then please contact the GGF and we’ll include it in the GGF Glossary.

Term	Definition
Acoustic Glass :	Glass that has been treated to improve it’s soundproofing qualities
Annealed Glass :	Annealing is a process of slowly cooling hot glass after it’s been formed, to relieve residual internal stresses that could cause breakage during manufacture. Annealing glass improves it’s durability
Approved Documents :	The Ministry of Housing, Communities and Local Government publishes guidance called ‘Approved Documents’ on ways to meet building regulations. These contain: – general guidance on the performance expected of materials and building work in order to comply with the building regulations – practical examples and solutions on how to achieve compliance for some of the more common building situations
Argon gas :	Double and triple glazed windows, commonly have argon gas between the panes to improve insulation and soundproofing. Argon gas is put into the glazing units because it is denser than air and therefore has greater insulating values than air.
Astrigal bars :	These are thin wooden moudlings placed on glass to create a period look. They are often used to create the traditional Georgian window look.
Awning windows :	These are casement windows that are hinged at the top of the frame.
Building Regulations :	Building regulations in the United Kingdom are statutory instruments or statutory regulations that seek to ensure that the policies set out in the relevant legislation are carried out. Building regulations approval is required for most building work in the UK. Building regulations that apply across England and Wales are set out in the Building Act 1984 while those that apply across Scotland are set out in the Building (Scotland) Act 2003.
British Standards :	British Standards are the standards produced by the BSI Group which is incorporated under a royal charter (and which is formally designated as the national standards body (NSB) for the UK). The BSI Group produces British Standards under the authority of the charter with the key objective being to set up national standards of quality for goods and services.
Casement window :	A casement is a window that is attached to its frame by one or more hinges at the side. They are used singly or in pairs within a common frame, in which case they are hinged on the outside. Casement windows are often held open using a casement stay. Windows hinged at the top are referred to as awning windows, and ones hinged at the bottom are called hoppers.
Construction Products Regulation :	Often abbreviated to CPR, the Construction Products Regulation was started in 2013 under the EU but was fully integrated into UK legislation in 2019. This guidance is about placing construction products on the GB market. The GB market refers to England, Wales and Scotland. There is a separate Construction Products Regulation for Northern Ireland. Also in the Republic of Ireland, the CPR is under the EU. The CPR is the legislation that underpins CE Marking and UKCA marking of constrcution products.
Composite doors :	Composite doors are made of a selection of materials often including core products such as timber and uPVC. Each material is chosen for its specific properties with the aim being that when combined they will make doors stronger and more durable.
Curtain wall :	A curtain wall system is an outer covering of a building in which the outer walls are non-structural, it’s purpose being to keep the weather out and the occupants in. Since the curtain wall is non-structural, it can be made of lightweight materials, thereby reducing construction costs. Glass is commonly used as the curtain wall this offers the advantage of increased natural light. In some cases glass curtain walling can also be used to describe full floor to ceiling glass panels installed in an building’s interior. This is common in office spaces and commercial buildings.
Double glazing :	Windows which have two layers of glass with a space between them, designed to reduce loss of heat and exclude noise.
Double hung :	Often used to describe a sash window that has two vertical sliding sashes within the larger window frame. Each sliding sash closes/opens a different part of the opening and usually has counterweight on each side.
Emergency glazing :	This is a common description when a window or door has been broken or damaged and requires an emergency glazing company to make safe, either by replacement or boarding up until a replacement can be installed. The GGF criteria for emergency glazing companies is that they operate at all times (24/7, every day of the year).
Emissivity :	The emissivity of a glass surface is its effectiveness in emitting energy as thermal radiation. Many glass manufacturers reduce emissivity by coating glass, allowing heat to remain inside the house and also to prevent solar heat coming into a property and causing overheating.
Energy ratings :	These are used to assess the total energy performance of products such as windows and doors in the same way that household goods like fridges are energy rated using the rainbow label system. A window or door energy rating will not only measure the total energy loss, as a U-value does, but also the energy gain and the air leakage through the window or door. In the UK British Fenstration Rating Council are the leading company when it comes to window and door energy ratings.
Fabrication :	Fabrication is the manufacturing process of cutting and assembling the window profiles (frames) together and adding hardware (handles, hinges, locks) along with weatherseals and gaskets to make a finished window (or door)
Fan lights :	A fan light is a glazed opening above a doorframe or above the lintel in a doorframe. It is usually designed to allow natural light into a hallway or darker area of a building.
Fenestration :	This is the process of positioning, installing and fixing a window, door or skylight in an opening in any type of building.
Fire-resistant glazing :	Fire Rated Glass (also known as Fire Resistant Glass) is specialist glass that has been proven to provide a period protection against fire during a Fire Resistance Test. Fire resistant glass is used in Fire Resistant Glazing systems (with special fire resistant seals and components). Fire resistant glazing systems will only work to maximum performance if installed correctly. Certain types of fire rated glass will also provide a degree of protection (insulation) against the heat of a fire.
Float glass	Float glass is a sheet of glass made by floating molten glass on a bed of molten metal, typically tin, although lead and other various low-melting-point alloys have been used in this process. This method gives the sheet uniform thickness and very flat surfaces. Float glass is the most commonly used glass in modern glazing (windows/doors/conservatories and curtain walling)
Glazier :	A tradesman responsible for cutting, installing, and removing glass. They also refer to blueprints to figure out the size, shape, and location of the glass in the building. Glaziers may work with glass in various surfaces and settings, such as cutting and installing windows, doors, shower doors, skylights, storefronts, display cases, mirrors, facades, interior walls, ceilings, and tabletops.
Heat soaking :	Heat soaking. The process involves placing the tempered glass inside a chamber and raising the temperature to approximately 290ºC to accelerate nickel sulfide expansion. The process reduces the risk of spontaneous breakage.
Heritage windows :	A heritage window is a type of window that has been manufactured specifically to be installed in a heritage building or building within a conservation area. These type of windows are made with modern materials and used as replica or close to replica replacements for the original windows in historic (usually 100 years or older) buildings
Insulating Glass Unit (IGU) :	An insulating glass unit (IGU) consists of two or more glass panes separated by a vacuum or gas-filled space to reduce heat transfer in and out of a building. A window with insulating glass is commonly known as double glazing or a double-paned window, triple glazing or a triple-paned window, or even quadruple glazing or a quadruple-paned window, depending upon how many panes of glass are used in its construction. IGUs are often referred to as “sealed units”.
Krypton gas :	An inert gas commonly used to fill small air spaces (cavities) between glass panes, resulting in improved year-round thermal performance. Krypton gas is sometimes mixed with Argon gas to fill the vacuum between glass panes in the production of insulated glass units.
Laminated Glass :	This type of safety glass holds together when shattered. In the event of breaking, it is held in place by an interlayer, typically of polyvinyl butyral (PVB), ethylene-vinyl acetate (EVA), or Thermoplastic Polyurethane (TPU), between its two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces. This produces a characteristic “spider web” cracking pattern when the impact is not enough to completely pierce the glass.
Lantern (roof lantern) :	Architectural lanterns are part of a larger roof and provide natural light into the space or room below. In relation to glass and glazing these are products that have a similar affect as skylights (roof windows)
Lightwell :	a lightwell, sky-well, or air shaft is an unroofed external space provided within a large building to allow light and air to reach what would otherwise be a dark or unventilated area. Lightwells may be lined with glazed bricks to increase the reflection of sunlight within the space
Low E Glass :	Low E stands for Low Emissivity. This is where glass has been treated to reduced energy being emitted from a building or into a building through panes of glass.
Mullion	A mullion is a vertical element that forms a division between units of a window or screen, or is used decoratively. When dividing adjacent window units its primary purpose is a rigid support to the glazing of the window. Its secondary purpose is to provide structural support to an arch or lintel above the window opening. Horizontal elements separating the head of a door from a window above are both a head jamb and horizontal mullion and are called transoms.
Processors (Glass)	Companies that buy flat glass and then put it through a process to make it perform differently. For example, to make it toughened glass through thermally heating.)
Profiles	These are the lengths of framing created by systems houses and framing manufacturers and are supplied to fabricators to trim and develop into window frames.
R-value :	the R-value is the term used for thermal resistance in a material. It is a measure of how well a two-dimensional barrier, such as a layer of insulation, a window or a complete wall or ceiling, resists the conductive flow of heat. R-value is the temperature difference per unit of heat flux needed to sustain one unit heat flux between the warmer surface and colder surface of a barrier under steady-state conditions.
Rooflight :	A window built into a roof and sometimes referred to as a sky light. These are usually installed to increase natural light into an area (such as a loft) where there may not be much natural daylight.
Roofline :	This is a generic description for the products that are installed at the edges of roofs and include fascia boards, soffits, bargeboards, antefixes and cladding that forms the frontage immediately below the roof and the eaves of many homes and building.
Sash windows :	A sash window or hung sash window is made of one or more movable panels, or “sashes”. The individual sashes are traditionally paned windows but can now contain an individual insulated glass unit to create a double glazed sash window.
Security glass :	This is a specialist type of glass that prevents easy breakage and makes it difficult for burglars or intruders to enter a property. Security glass can be toughened glass (sometimes known as tempered glass), laminated glass or wire mesh glass (glass with wire mesh inside sometimes known as Georgian wire glass – not so common today).
Secondary glazing :	This is a glazing system that is installed inside a property when there are restrictions to replace the exterior windows. Secondary glazing often installed in historic buildings and is fixed to the sill inside the building. It
Self-cleaning glass :	Self-cleaning glass is a specific type of glass with a coated external surface that keeps itself free of dirt and grime. The field of self-cleaning coatings on glass is divided into two categories: hydrophobic and hydrophyllic. These two types of coating both clean themselves through the action of water, the former by rolling droplets and the latter by sheeting water that carries away dirt. Hydrophilic coatings based on titania (titanium dioxide), however, have an additional property: they can chemically break down absorbed dirt in sunlight. This is often an option for hard to access windows.
Sight line :	The perimeter of a window opening that admits daylight into living and work areas.
Single glazing :	A window that has one pane of glass. This type of glazing is usually found in older windows and is the least energy efficient glazing option.
Skylights :	A description often used for roof windows or rooflights
Solar gain :	Solar gain (also known as solar heat gain or passive solar gain) is the increase in thermal energy in a building as the glass (in a window) absorbs solar radiation via sunlight. This can cause overheating in a building.
Spacer bar :	A spacer bar is the thin hollow aluminium frame that separates the two glass panes in a double glazed window. The spacer bar is bonded to the glass panes via a primary and secondary seal, creating an airtight cavity enabling it to be filled with air or gas to reduce heat and sound transfer.
Tilt and turn :	Tilt and turn windows can be opened fully like a casement window (inwards) or they can be tilted from the bottom so that the top of the window is angled into the room, giving a smaller opening for ventilation. The tilted opening also has the added benefit of increased security and safety as no one can fit through the gap.
Trickle ventilator :	A trickle ventilator (sometimes called trickle vent) is a very small opening in a window that allows small amounts of ventilation in spaces intended to be naturally ventilated when major elements of the design – windows, doors, etc., are otherwise closed. Trickle vents are used extensively in the UK and Europe and are integrated into window frames to provide minimum ventilation requirements for naturally ventilated spaces.
Toughened glass :	Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass.
Triple glazing :	A insulated glass unit or window that has three panes of glass with two spaces (vacuums) separating the panes. The vacuums are usually filled with argon gas to reduce heat loss. Triple glazing can offer great security and can be more effective for thermal performance.
UPVC :	UPVC is an abbreviation or Unplasticized PolyVinyl Chloride and is a rigid, chemically resistant form of PVC used for pipework, window frames, and other structures. UPVC is sometimes referred to as PVC-U or plastic or PVC when describing double glazing.
U-Value :	U-values measure how effective a material is an insulator. The lower the U-value is, the better the material is as a heat insulator. U-values are generally used to describe the thermal performance glazing/windows.
Vertical sliders :	Another name for a double hung sash window
Warm edge :	A warm edge spacer is a type of spacer bar used in insulated glazing. It separates the panes of glass in double or triple glazing, or curtain walling and seals off the air cavity between each. Recent warm edge spacers are generally made from plastics, although stainless steel can meet the definition.
WER (Window Energy Rating) :	A rating systems led by the British Fenestration Rating Council (BFRC), that reviews the whole energy performance of a window, including all of its components. Ratings can go from highest triple A to lowest F and is presented in the rainbow labelling style often seen in white goods such as refrigerators
Window Film :	Window film is a thin laminate film that can be installed to the interior or exterior of glass surfaces in the interior or exterior in homes and buildings. It’s often used to increase privacy, solar control, safety and security or to block out strong sunlight. Window film should be installed by professional service companies to ensure best performance.

Works of art: Super Spacer® helps to bring landmark galleries to life

Members News | 31.05.23

Edgetech’s world-renowned Super Spacer® has been integrated into the window units of thousands of striking and ambitious buildings around the globe – including dozens of stunning art galleries and museums.

The Twist is part gallery, part bridge and part sculpture – a 1,000 square-metre landmark that spans the Randsleva River in the Norwegian forest.

Ten quadruple-glazed insulating glass units make up the building’s structural façade, with the free-form units having been manufactured using Super Spacer® TriSeal™. A PVB film blocks the UV radiation to shield the priceless artworks within from sunlight.

Also located in Norway is the Salmon Eye – a giant, four-floor floating art installation, designed to educate visitors about the vital importance of sustainable fishing.

The structure’s ellipsoidal shape is modelled on a salmon’s eye, with the outer layer made of 9,250 stainless steel plates designed to imitate a fish’s shimmering skin.

The installation weighs an incredible 1,256 tonnes, making extensive use of curved and laminated safety glass units created with Super Spacer® TriSeal™ Flex.

Meanwhile, the Musée Atelier Audemars Piguet in the Swiss mountains aims to tell the story of the country’s long tradition of watchmaking. The building takes the form of a glass double helix which is embedded into the landscape and has the appearance of a giant watch spring. It consists of an all-glass curved facade, a 470-tonne green steel roof, and a striking sunshade louvre fashioned from untreated brass.

Regularly exposed to temperatures of well below -20°C, the triple glazed insulating glass, manufactured with Super Spacer® TriSeal™ Flex in black, has been engineered to achieve incredible U Values of just 0.5 W/(m²K).

Edgetech Managing Director Chris Alderson comments: “Whether in the Swiss mountains, Norway’s arctic climate, or the hot deserts of the Arabian Peninsula, Super Spacer® TriSeal™ has repeatedly demonstrated its ability to easily withstand the toughest weather conditions to offer outstanding overall performance.

“For us, it’s immensely gratifying to see our products help make some of the most architecturally ambitious buildings in the world a reality.

“This is especially the case when the structures themselves are just as impressive as the artworks they were designed to contain.

“As architects continue to strive to push the boundaries of what is possible, Edgetech’s products will continue to enable them bring their visions to life”.
