What's involved with fire-resistant glass in Willesden
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
- Glazing beads and fixings to the frame manufacturer's details
- Integrity with radiation control (EW) laminated glass
- Impact-classified build-ups for critical locations
Before you order fire-resistant glass: what matters
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.
Weight and handling
Insulating fire glass gets thicker and heavier as the rating rises. Large EI 60 and EI 120 panes often need lifting equipment and a frame designed for the load, which we plan before the delivery date.
Marking and records
Most fire glass is permanently marked with its product and classification. We record the marks, pane sizes and evidence references on handover so whoever is responsible for fire safety can show what is installed.

Questions about fire-resistant glass in Willesden
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.
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.
Which rules apply to fire-rated glazing in Willesden?
Building work in Willesden follows the Building Regulations 2010 and Approved Document B, and occupied buildings are covered by the Regulatory Reform (Fire Safety) Order 2005.
Do you carry out fire-resistant glass in Willesden?
Yes. We survey and install in Willesden and across Greater London, including the NW10 district and nearby Cricklewood.
