Envirograf FCS1/30/60 Intumescent-impregnated Fireproof Sponge (1-hour

[[start desc]]

Fireproof Intumescent Sponge impregnated and coated with intumescent material. Very flexible, but remains stable in small or large apertures. The sponge will not burn, it will simply char, in the event of a fire. As a result, it provides an extremely effective fire-stopping barrier, in effect providing passive fire protection.

Available in sheets or strips from 10mm to 100mm thick to suit a variety of fire-stopping applications. See our references tab for the full availability of sizes. Additionally, unaffected by water or chemicals. The intumescent material is a substance that swells as a result of heat exposure, therefore leading to an increase in volume and decrease in density
