Fire and smoke seals.Intumescent fire and smoke seals for a safe and effective barrier against fire, cold smoke and hot gases.

Application:

Intumescent fire and smoke seals for fire door assemblies. An ASTRO intumescent graphite 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.
