FIRE RETARDANT AND SMOKE-GUARD DOOR BARRIER

摘要

A smoke-barrier device for securely sealing the spaces beneath and around a door and a fire and smoke retardant door cloth panel will gain two or more hours for a person(s) trapped by a fire in a closed room, even one that has a residential style wood door that is known to burn in about 20 minutes. The combined use of the tested and rated smoke-guard device and the tested and rated fire and smoke retardant panel will prevent fire, smoke, and lethal gases from entering the room through a doorway even after the wooden door burns through.
