Firestop manufacturing 15x4mm intumescent strips for doors are designed to be rebated into either the door leaf or frame, to seal off the sides and head of the door in the event of a fire.

The graphite based material in the seal expands by up to 15 times its original size to seal off the gap when exposed to high temperatures.

All seals act as a fire barrier. If you require cold smoke protection, select the fire and smoke seal, which comes with a brush to prevent the passage of smoke.

Standard brush pile length: 4mm sticking out of the brush holder.
