What our fire-resistant glass service includes in Lowestoft
Fire-resistant glass is glazing that has been tested, as part of a complete glazed system, to hold back fire for a set time. It is classified by what it stops: E (integrity) keeps flames and hot gases on the fire side, EW also limits the heat radiated through the glass, and EI (integrity and insulation) also limits the temperature rise on the protected side, so people can pass it more safely.
- Insulating (EI) intumescent-interlayer and gel-filled glass
- Intumescent glazing seals, tapes and gaskets to the tested specification
- Integrity (E) glass: modified toughened, glass-ceramic and polished wired types
- Impact-classified build-ups for critical locations

What to check before ordering fire-resistant glass in Lowestoft
Inside or outside?
Many insulating fire glasses use interlayers that need protecting from UV and moisture, so external positions need a product approved for exterior use, with the right edge seal and glazing system.
Which classification do you actually need?
The fire strategy or building control drawings set the rating for each element. Integrity-only glass is cheaper and thinner, but its use on escape routes is restricted; insulating glass carries far fewer restrictions because people can pass it safely during a fire.
Can any fire glass go in any fire-rated frame?
No. A frame is only rated with the glass types and pane sizes it was tested or assessed with. We check the frame's evidence before quoting, and if the existing frame is unknown we say so and price the options.
Fire glazing rules in England
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.

FAQs for Lowestoft
Do you supply fire glass only?
Our service is supply and installation, because the rating depends on how the glass is fitted. For trade buyers we can quote supply of cut-to-size panes with the matching glazing materials on request.
How thick is fire-resistant glass?
Integrity glass can be similar in thickness to standard glass. Insulating glass is laminated from several layers, so it gets markedly thicker and heavier as the rating increases from EI 30 to EI 120.
How quickly can you survey in Lowestoft?
Survey timing in Lowestoft depends on access, the size of the building and how urgent the defect is. Tell us your deadline when you enquire and we will confirm a date before you commit.
Do you work on occupied buildings in Lowestoft?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
