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.
Intumescent Fire Seals are available with or without a cold smoke seal in the form of a nylon pile.
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.
All fire and smoke seals are supplied with a self-adhesive backing tape as standard to facilitate quick and easy fitting.
Tested for 30 minutes with 10mm and 15mm to BS 476 part 22 & 31.1.
