Fire-Resistant Glass in Stevenage: what's included
We supply and fit fire-resistant glass into new and existing fire-rated frames, matching the glass type, thickness, beads, seals and fixings to the test or assessment evidence for that frame. The glass on its own does not carry a rating; the combination does, so we start every job by identifying the system you have or need.
- Integrity with radiation control (EW) laminated glass
- Integrity (E) glass: modified toughened, glass-ceramic and polished wired types
- Insulating (EI) intumescent-interlayer and gel-filled glass
- Impact-classified build-ups for critical locations

What to check before ordering fire-resistant glass in Stevenage
Impact safety still applies
Glass in doors, side panels and low-level positions has to meet impact safety rules as well as the fire rating. Most modern fire glass carries an impact classification; old wired glass usually does not.
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.
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.

FAQs for Stevenage
Can you match glass that is already installed?
Often, yes. We read the marks on the existing panes and check them against the frame evidence. Where the original product is discontinued we look for an alternative covered by the same evidence or a formal assessment.
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.
Which rules apply to fire-rated glazing in Stevenage?
Building work in Stevenage follows the Building Regulations 2010 and Approved Document B, and occupied buildings are covered by the Regulatory Reform (Fire Safety) Order 2005.
Do you work on occupied buildings in Stevenage?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
