INTUMESCENT FIRE SEALS

Intumescent Fire and smoke seals for fire door assemblies.

Intumescent Fireseals are available with or without a cold smoke seal in the form of a nylon pile or rubber seal. 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 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 decor.
