20x4 Brown Intumescent Strip
A fire protection sealing solution designed to expand when exposed to heat, helping to slow the spread of fire and smoke through door gaps.

Details
Commonly fitted into fire-rated timber doors and frames, it plays a critical role in maintaining fire integrity in residential and commercial buildings.
When exposed to high temperatures, the strip expands many times its original size, sealing gaps around the door leaf to restrict flames and smoke. The brown finish allows it to blend discreetly with darker timber doors and frames for a neat, unobtrusive appearance.
Ideal for fire door installations, upgrades, and compliance work, this intumescent strip is suitable for both trade professionals and approved fire-safety projects.
