Swinging fire doors are critical components of maintaining building compartmentation. The ability for swinging fire doors to resist the passage of fire and smoke and to comply with the applicable standards are affected by the gap sizes around a fire door (i.e. between the frame and the hinge side(s) of the door, between the latch side(s) of the door, between the frame and the top of the door, and between the bottom of the door and floor). Hence these gap sizes are regulated. NFPA 80 currently allows a maximum bottom gap of 3/4” and a maximum of 1/8” for the perimeter of the swinging fire doors. The clearance under swinging fire doors is frequently found to be greater than the maximum allowable gap size currently allowed by NFPA 80.   The upcoming webinar, "Influence of Gap Size around Swinging Doors on Fire and Smoke Development," will address the performance of the clearance dimension around single- and double-egress swinging fire-rated wood and steel doors on fire development and smoke movement in an NFPA 252, Standard Methods of Fire Tests of Door Assemblies, furnace environment.
