Anatomy of a doorset
Every part is rated.
Tap a point on the door.
Clear glazing rated with the doorset, for 1 or 2 hours. It stays in the frame while the fire is on the other side.
A steel frame with powder coat or a stainless steel capping finish, like this one.
Seals that swell with heat and close the gaps where the leaves meet the frame.
Handles, hinges and locks that belong to the certified system, not off the shelf.
The fixed glass above is part of the same rated doorset, so the whole opening holds.
Before and after
Same exit. Now clear.
A solid steel exit door, replaced with fire-rated glass. Drag to compare.

Which ratings do you supply?
1-hour and 2-hour doorsets and screens, matched to what the Fire Code requires at each opening.
How do I know a door is certified?

Often, yes. That is the before and after above. We confirm the rating that opening needs first.
