Get Technical Support
We understand the importance of providing the very best in Technical Support for our members and our team has a wide and extensive range of experience in both glass and Fenestration matters. Members needing a quick answer can contact a member of the team by dialling our Member Exclusive Hotline number which can be viewed by clicking here which will be answered by the first available Technical Officer.
For more complex or detailed queries, send your email to firstname.lastname@example.org Our inbox is prioritised with members’ emails answered same day/next day. No matter the issue, our aim is to provide the best support in quality and response. Please note that non-members can only enquire by email.
In an ever-changing industry landscape, it is vital that members are fully aware of changes in legislation and standards that are in development or implemented. Our team analyse and evaluate documents issued by MHCLG and the Welsh, Scottish, Northern Irish and Irish Government. This covers all ISO, CEN & BSI Standards for our industry whether for review, comment or implementation as well as information provided by associated organisations such as the CPA, CWCT and Glass for Europe.
All relevant material is collated and issued to members in our Quarterly Reports and also provided in Presentation form at all Technical and Regional Group meetings. This is also available for download from this page. In addition, this page includes details and links to any documents relevant to our members as and when they are introduced.

Site Visits & Consultancy
Regrettably, disputes between installer and consumer can occur and result in deadlock. The GGF can visit sites and provide inspection reports covering aspects such as product suitability, quality of installation, compliance with Building Regulations; Industry Standards and Good Practice Guides. Similar disputes involving contractors and professional bodies are also covered in this service.
Reports by the GGF are a well established and recognised form of evidence in Courts throughout the UK and Ireland and is also further enhanced with an Expert Witness Service. This is a chargeable service, however, members will receive a favourable discount.

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
Datasheets, Good Practice & Guidance Documents
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.
Conformity Marking – CE & UKCA Marks
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.
