What every Leatherhead quote includes

After survey you get a fixed written quote for the agreed scope, so Leatherhead budgets are not open-ended.
What to check before ordering insulated fire glass in Leatherhead
How it works
When heated, the interlayers turn opaque and expand, forming an insulating shield. After a fire the glass will need replacing.
Exterior positions
Some EI products are internal only. External use needs a product and edge seal approved for UV and weather.
Optical quality
Modern EI glass is clear in normal use, with high light transmission at lower ratings.

England regulations that shape the job
England Which rules apply?
Building work in England is covered by the Building Regulations 2010, with fire safety guidance in Approved Document B and impact safety guidance for glazing in Approved Document K.
Once a building is in use, the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to maintain fire safety measures, including fire-resisting glazing. The Fire Safety (England) Regulations 2022 add duties for multi-occupied residential buildings, including fire door checks in buildings over 11 metres.
In higher-risk buildings, broadly 18 metres or seven storeys with two or more homes, the Building Safety Regulator is the building control authority. England is also phasing out BS 476 references from Approved Document B, with the remaining fire-resistance references due to go in September 2029.
Sectors we cover in Leatherhead
Insulated fire glass applies to many building types in Leatherhead, including industrial units and retail and leisure units.
FAQs for Leatherhead
Does EI glass need replacing after a fire?
Yes. Once the interlayers have reacted, the glass has done its job and must be replaced.
What does EI 60 mean?
The glazing system kept fire on one side (integrity) and limited the temperature rise on the other side (insulation) for at least 60 minutes in a standard fire test.
Can you price insulated fire glass in Leatherhead from photos?
We can give a guide range from photos and sizes, including a clear photo of any marks on the glass. A fixed price follows a survey.
Do you work on occupied buildings in Leatherhead?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
