Our best-selling intumescent strip comes fire-tested in accordance with BS 476: Part 22: 1987. It has a moisture resistant material that is suitable for both wet and dry applications on a range of single and double leaf door sets (please see our 'downloads' section for further information).

The Pyroplex® intumescent strip has a number of useful features, including a high tack self-adhesive backing and a compression gap on the back of the seal that gives the user the flexibility needed to fit the seal into those tighter gaps on site.

Intumescent seal sizes range from 10x4mm up to 38x4mm for those specialist applications. Supplied in a standard 2100mm length as well as 1050mm and 3000mm, this fire door seal can easily be cut to size.
