Door seal.
Fire resisting door assemblies.
Therm-A-Stop has been designed for use in fire resisting door assemblies which have been designated as smoke control doors. The seal slows the spread of smoke and fire through a building by reducing the flow of smoke and air through the gaps between the leaf and the frame or an adjacent leaf edge during the early stages of a fire. The reduced flow of air through the door assembly also restricts the growth of the fire by reducing the amount of oxygen available.
Activated by heat, the foam rapidly expands sealing the air gaps between the leaf and frame, foaming a compact mass of heat resistant graphite insulating and retarding the spread of the fire through the doorset.
