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.
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 1st September in London, where he will be highlighting the Group’s activity.

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

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:
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.

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.”

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 31st 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 6th. 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 18th 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

As the boundaries of building design are constantly expanded, it is our industry’s duty of care to ensure that installations are within acceptable and safe parameters. This ranges from glass floors and stair treads to structural glass systems for the building envelope. At the GGF we can provide the relevant calculations including glass requirements and loadings using MEPLA software. SJ MEPLA is a finite element program specially developed to perform static and dynamic calculations of glass structures.
You can calculate any shape of a system including laminated glass, point fixings, balustrade clips and all this for insulated glass. Any bearing and loading situations are possible. You can consider load cases or dynamically calculated impacts for the use of glass as fall protection
Long recognised as a major asset to our members, our Technical library continues to expand. Regularly reviewed and expanded, the library is divided into 3 categories: –
Datasheets: Source documents for the industry covering details on products such as IGUS, Toughened, Laminated, Curved Glass, Window Film, Windows, Doors and Hardware. Click here
Good Practice Guides: detailing installation standards and requirements e.g. Windows, Doors & Conservatories.
Guidance for Trade & Consumers: explanatory documents covering topics such as condensation, roller wave, anitroscopy & visual inspection.
All are free to download for members in PDF format. Non-members can purchase from the GGF Shop.
In this period of adjustment since leaving the EU, the transfer to UKCA marking from the European CE mark has caused issues and confusion thoughout the Construction Industry which is further complicated due to a lack of clarity from the Government for many of the basic principles and operational details. The CE mark will cease to be acceptable in Great Britain from 1st of January 2022. The use of UKCA became effective from the 1st of January 2021.
The introduction of the UKCA conformity mark along with CE UKNI and the relevant test certification is a complex matter, not least when compliance with the NI Protocol is also a consideration. Members, however, can be assured of receiving accurate guidance and advice on how to minimise business disruption during this period.
The Technical team will continue to inform members of any updated information or changes in regulations.

A new document laying out the proposed changes to the European version of the Construction Products Regulations has been published. This is now out for Public Consultation closing on the 3rd June 2022. Technical Officer Steve Chappell has summarised the document including a comparison table for the new AVS system proposed to replace the current AVCPs which you can view/download by clicking here.
Members can download the full consultation document by clicking here.
After some COVID related delays we are delighted to inform members that the Inaugural meeting of the Aluminium Group will take place on the 21st April at Solihull Moors FC at 10:30am. Members who have not yet confirmed attendance should contact Kevin Jones at kjones@ggf.org.uk
Despite the efforts of the GGF in conjunction with the Construction Products Association (CPA) and the Construction Leadership Council (CLC) by meeting with BEIS and DLUHC every two weeks, the issue regarding AVCP3s remains as it was in late 2021. Government have finally acknowledged the problem and as an interim measure have issued a new document which would appear to allow UK CABs to sub-contract testing for new products in Europe. However, the issue with historic data for AVCP3s still remains. We are assured that a resolution to this issue is imminent and is currently with the Paymaster General for approval.

During 2020, despite the pandemic and industry lockdown, the GGF continued to function and deliver high-quality services and publications to its Membership.
Here’s a breakdown of the GGF’s headlines in 2020.
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 4th 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.
Please find listed below the complete list of available GGF technical and membership publications with quick direct links to each publication.
Some of the datasheets marked “in progress” means they are under review by the GGF Technical team, however where there is a link the current versions are still available until any changes are made.
The GGF Health and Safety publications can be found in a separate section. Please go here if you are looking for Health and Safety publications. https://www.ggf.org.uk/publications/health-and-safety-publications/

David Borland – Head of Technical Department
With over 40 years of experience in the industry, David is well placed to provide both practical and technical advice to members. Starting as an Apprentice Glazier in his early years, David moved into IGU production. A passion for product development seen him expand into other areas of glass production such as toughening, pre-processing, decorative glass and laminated glass. He was the Project Director for the planning, purchasing and commissioning of the World’s first Jumbo PVB Laminating line based in Glasgow.
A turn in direction seen David moving into fabrication and installation of aluminium windows and doors, both commercial and domestic. The addition of uPVC windows and Doors was a natural progression.
Latterly, his experience and knowledge offered opportunities to move to and work in the Middle East, India and Malaysia.

Steve Chappell – Technical Officer
With over 20 years’ experience in the glass industry in technical and commercial roles Steve started out as a Technical Advisor for a major UK glass company providing design advice and technical support on all aspects of glass and glazing. Delivering a technical consultancy service in-house to branches and their customers nationwide, to design professionals, the industry and the general public.

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.

The GGF Technical department contributes to the development of National, European and International Standards to the benefit of GGF Members and the industry as a whole.
GGF Technical officers represent the views of the GGF Membership to standardisation bodies at National, European and International levels. These include:
Read the latest on UKCA marking here
The GGF holds a comprehensive library of British, European and International Standards, monitors changes to standards, and keeps GGF Members and the industry informed of any significant developments.
Technical standards of the glass, glazing and fenestration industries could be affected if they are aligned to EU legislation, in particular, the Construction Products Regulation (2103) and related hENs (harmonised European Norms/standards).
Harmonised European Standards
Harmonised European standards provide a technical basis to assess the performance of construction products. They enable manufacturers to draw up the Declaration of Performance as defined in the Construction Products Regulation and affix the CE marking.
What are harmonised standards for:
Harmonised European standards create a common technical language used by all actors in the construction sector to:
Supporting testing standards relevant to construction products cover:
Meeting the Standards
When placing construction products on the European market, European Standards which have been ‘harmonised’ (hEN) following a request, known as a mandate, from the European Commission, must be used by manufacturers, importers or distributors (known collectively as ‘economic operators’), to ensure the performance characteristics declared are established using standard Type Testing and in some cases such as Resistance to fire, have independent, third party product certification, carried out by Notified Bodies established under the Construction Products Regulations (CPR). Notified Bodies (NBs) are accredited by a National Accreditation Body (NAB), in the case of the UK this is UKAS. The use of NBs in determining the performance of the products Essential Characteristics (ECs) ensure that these ECs are declared using the same test standards. The accreditation of the Notified Body by an NAB should ensure that testing is carried out by a test houses and certification carried out by product certification bodies are to the same hEN and the requirements of those hENs are interpreted in the same way.
The CPR requires all construction products within the scope of a hEN, must have a Declaration of Performance created by the economic operator and the product must be CE marked.
The development of hENs was the result of the EU’s Construction Product Directive which changed to the Construction Products Regulations in 2011, implemented in the UK on 1 July 2013.
As previously stated, the Standards landscape may be confusing due to the use of standards developed by different organisation, this can be demonstrated by the following examples:
It is important that manufacturers of construction products understand the relationship between hENs and their supporting standards to enable them to comply with the requirements of the CPR and place construction products on the market in compliance with the CPR.
The effect of the UK leaving the EU WITH a ‘Withdrawal Agreement’
If the UK leave the EU with the WA negotiated between the Government and EU-27 on 19 October 2019, there will be no change to the status of the Construction Products Regulations in the UK or the status of European Standards during the transition/implementation period. In particular, hENs will remain as the method of determining and declaring the performance of the Essential Characteristics (ECs) which manufacturers of construction products declare in the products Declaration of Performance (DoP) and CE label. New or revised hENs and other European Standards will be published in the UK by BSI during the transition/implementation period and will be effective during this period.
This situation will remain during the transition/ implementation period that is due to end in December 2020 unless it has been extended by up to 2 years following a request by the UK to extend it is made by July 2020.
The status of UK Notified Bodies will remain in force during the period of transition/implementation based on Article 43 and Article 46 of the WA and therefore existing Certificates of Constancy of Performance, as required for Attestation and Verification of Constancy of Performance (AVCP) System 1 Essential Characteristics, will remain valid for that period.
Existing Type Testing carried out by a UK Notified Body will also remain valid for the duration of the transition/implementation period. It is expected that any Type Testing carried out before the end of the transition/implementation period by a UK Notified Body, will remain valid for compliance to the Construction Products Regulations in the UK and the European market after the end of the transition/implementation period.
If changes are made to the product and those changes affects the performance of an Essential Characteristic, new Type Test evidence will be required. New Type Testing after the end of the transition/implementation period will need to be carried out by an appropriate body as defined in the trade agreement between the UK and EU-27.
During the transition/implementation period, trade negotiations will take place between the UK and EU-27 with the intention of developing a comprehensive trade agreement that will become effective at the end of the transition/implementation period. This Trade Agreement will provide details of any change in status of the CPR, UK Notified Bodies and European product standards.
The effect of the UK leaving the EU WITHOUT a ‘Withdrawal Agreement’
In the event of the UK leaving the EU without a WA, the following changes will take place:
Standards
The Construction Products Regulations (CPR)
Existing product DoPs and CE marking if the UK leaves the EU without a Withdrawal Agreement
Note: These will be identical on the day following the UK leaving the EU without a WD but may not continue to be identical as UK and EU standards may diverge over time.
Summary of actions for businesses and other stakeholders following the UK leaving the EU without a Withdrawal Agreement
What next?
The changing landscape of Brexit will require the GGF to have a close watching brief on events with continuous meetings and discussions with various Government departments, working parties, standards committees and related bodies.
The GGF will cascade any key information of any potential changes to technical standards directly to Members and the wider industry.
Visitors to this section of the Brexit Hub are advised that all technical updates on standards and regulations in relation to Brexit, will appear on this page.
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.
