| Description | Intumescent fire and smoke seals for fire door assemblies. An Astro intumescent grafite based fireseal contained within a pvc sleeve fitted into a rebate to either the leaves or the frame will in the event of a fire expand (intumesce) to many times its original volume and seal 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 smokeseals provide a permanent barrier to smoke, acoustic and thermal applications and are particularly important as smoke travels faster and further than fire itself, all astro seals are supplied with a self adhesive backing tape as standard to facilitate quick and easy fitting. The seals are available in a choice of colours to suit your requirements or blend with the decor. Tested for 30 minutes with 10mm and 15mm to BS476 part 22 and 31.1 and Certifire approval. Tested for 60 minutes with 20mm to BS476 part 22 & 31.1. Smokeseal to 100,000 cycle test. LANTAC Building Control and NHBC Type Approval. |
