Intumescent fire and smoke seals for fire door assemblies. An intumescent graphite based fireseal 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 Fireseals are available with or without a cold smoke seal in the form of a nylon pile. Astroflame smoke seals provide a permanent barrier to smoke – particularly important as smoke fumes travel faster and further than the fire itself. They also have acoustic and thermal applications.
Price shown is for white and brown only, all other colours priced on request.
