The 4 glass-hard rules of assembly
Fire resistant glass only works if 'the system' is right.
1. The frame is sacred
Are you installing fire-resistant glass in a frame? To comply with the fire-resistant requirement, the frame construction (wood/steel/aluminium), installation and the materials to be used must meet the requirements of the test report. Check, among other things, the rebate depth!
2. Space to work (rebate)
Fire-resistant glass can expand or become opaque (froth up) when heated.
Rule: Ensure sufficient circumferential clearance. Strictly follow the requirements from the test report to allow for expansion and foaming. Glass should never touch the frame or the adjustment pads.
3. The right cubes
Don't use standard plastic cubes, they melt.
Rule: Use only adjusting blocks as prescribed in the test report, combined with ceramic tape and fireproof sealant or intumescent sealant that complies with the regulations.
4. Stamp is proof
Do not remove the stamp on the glass, the stamp should be and remain visible.
Why: The supervisor/fire brigade must be able to see that it is certified glass.
No stamp = rejection
Which glass for which requirement?
1. Understand the abbreviations (The ABC of fire)
E = flameproof
Stops flames and smoke. (The glass remains whole, but heat gets through).
EW = Heat-limiting
Stops flames + limits radiant heat (so escape routes remain passable). Most common!
EI = Insulating
The glass does not get hot on the other side. (You won't burn your hand). The highest requirement.
2. The 3-step check
How long?
30, 60, 90 or 120 minutes (WBDBO requirement) .
Which way?
Should the fire be turned inside out or the other way around?
Is there a level difference?
Does the glass also need to be fall-through resistant? (Then choose fire-resistant glass that also meets classification 1B1 according to NEN - EN 12600).
3. Dangerous trap!
Normal glass + fire-resistant foil = IMPOSSIBLE
Seldom meets the official NEN standard for constructions.
Wire glass?
= often no longer sufficient under the new Bbl requirements for new licences.
APPLICATION
Fire-resistant insulating glass is often used and, in some cases, is even mandatory in both new and existing buildings. For example, to guarantee safety in public buildings or day-care centres. We also see more and more fire-resistant insulating glass in residential construction.

"Martin Glas supplied and fitted all interior glazing for the Huygens Lyceum. Soundproof glass was used for all classrooms. Classrooms where, for example, subjects such as physics and chemistry are taught, which include gas, heat and open flames, have been fitted with the required fire-resistant glass."
