Intumescent fire and smoke seals for fire door assemblies. An intumescent graphite based fire seal contained within a PVC sleeve for fitting into a rebate to either the leaves or the frame of a door. In the event of a fire the seal expands (intumesces) to many times its original volume and seals the gap around the door to provide a safe and effective barrier against the passage of fire, smoke and hot gases.

Astroflame Intumescent Astro Strip SB Single Neoprene Single Blade Fire & Smoke Seals are fitted with a cold smoke seal in the form of a black neoprene single blade. Astroflame smoke seals provide a permanent barrier to smoke - particularly important as smoke fumes travel faster and further than the fire itself.

All Astro fire and smoke seals are supplied with a self-adhesive backing tape as standard to facilitate quick and easy fitting.
