Loose glass in glazed fire door

[redhexagonal]

I bought this glazed FD30 fire door and the glass moves a bit and rattles . Is this normal?

It should be bedded in on an intumescent sealant of some sort.

I can’t really tell if it is..maybe there is something black in there? So should a seal prevent the glass wobbling?

The sealant is a special fire sealant that is designed to keep the glass in place for as long as the fire door is rated. No sealant and smoke /fire could get around the glass

Yes I know, but I can’t tell if there is a sealant

Ring the manufacturer. It could just be that the seal is out of sight beneath the bead but nevertheless I wouldn't expect it to be loose, the glass will still rattle every time the door's closed. Even assuming there is a seal that will expand if smoke touches it (not sure it will unless the smoke is pretty hot). Is it and FD30 or and FD30S? Assuming it is a fire door it would have a label on the top or side showing its certification.
