Fire door glazing must be what type?

Explanation:
Fire door glazing must be fire-rated. The glass used in fire doors is required to have a fire-resistance rating that matches or exceeds the door’s own rating, so heat, flames, and smoke are contained for the specified duration. Ordinary glass, even if tempered or laminated, will not necessarily withstand the heat unless it is specifically rated for fire resistance and installed as part of an approved fire-rated assembly. Using fire-rated glazing ensures the door maintains its integrity during a fire and helps protect occupants as intended.
