A 90-minute B door rating refers to a fire-resistance rating for a door, indicating that it can withstand exposure to fire for up to 90 minutes. The "B" classification typically signifies that the door meets certain standards for smoke and flame containment, making it suitable for use in areas requiring enhanced fire protection, such as between different compartments of a building. This rating is crucial for ensuring safety during emergencies by allowing for safe passage and evacuation.

When are 90 minute fire rated doors required?
90 minute doors are required when building code requires a 90 minute or 2 hour assembly rating. For example, with IBC '06, 715.4, if a 2 hour wall is required, you can have a 90 minute door. The fire resistance rating depends on the type of building occupancy and component. For example, for fire barrier assemblies or horizontal assemblies, for occupancy of type A (Assembly), B (Business), E, F-2, H-4, H-5, I, M (Merchantile), R, S-2, the fire rating is 2 hours. For other types, say U (Utility) the rating is 1 hour and for H-1 and H-2 (High Hazard) its 4 hours. Since the issue is complex, consult an architect to determine a specific application.
