Fire Door Info

- Feb 16, 2019-



A fire door is a door with a fire-resistance rating (sometimes referred to as a fire protection rating for closures) 

used as part of a passive fire protection system to reduce the spread of fire and smoke between separate compartments 

of a structure and to enable safe egress from a building or structure or ship. In North American building codes, it, along with fire dampers, 

is often referred to as a closure, which can be derated compared against the fire separation that contains it, provided that this barrier is not a firewall or an occupancy separation.
