Astroflame fire & smoke intumescent strip with brush is suited for use on fire door assemblies. An intumescent fireseal is fitted into the rebate to either the door or the frame and will expand to many times its original size in the event of fire, thus sealing the gap and providing effective barrier against the passage of fire, cold smoke and hot gases.
- Tested for 30 (10x4mm and 15x4mm) or 60 (20x4mm) minutes to BS 476 part 22 and 31.1. Certifire approved.
- Single, self adhesive strip supplied. Length: 2.1m.
- Three (two and a half to be exact) strips are usually needed to completely outfit the fire door assembly.
In order to fully comply with the fire regulations all door's 'weak points', such as hinges, locks, door closers etc., should be protected with intumescent sheets - see below.
