Therm-A-Seal - Fire Door Seal

Door seal designed primarily for sealing the air gap between the edges of the leaves and the frame, or between the separate leaves, of both timber and steel fire resisting door assemblies in the event of a fire.

The intumescent foam produced by the product has high temperature tolerances and so is well suited for use with steel framed timber door assemblies where conventional intumescent foams may break down.
