What do you check on a glazed fire door?
Get a priceYou check the glass, the beads that hold it, and the seal between the two. The glass has to be fire-rated glass, and it should be marked.
Look for an etched mark in a corner of the pane. Fire-rated glass is normally stamped or etched with a rating and a maker's name. Ordinary glazing has no mark that says how long it holds.
What can go wrong
The beads are the wooden or metal strips that keep the glass in place. If they have been replaced with ordinary beads, or fixed with the wrong pins, the glass may fall out sooner in a fire.
Intumescent seals sit between the bead and the glass. If they are missing or painted over, the glazing may not do its job.
Cracks in the glass are a fault. So is a pane that has been swapped for a plain one.
Glazed screens
A door in a glazed screen, such as the one in the photo, has the same checks on the door and a separate set on the frame and panes. The screen is part of the fire barrier, so each pane needs the same mark.
What we do
We check every pane, bead and seal. We photograph the etched mark where there is one. If there is no mark we write that down and say what your options are. Do not guess. A pane that looks like fire glass may not be.
