Metacaulk Intumescent Sleeve

Metacaulk Intumescent Sleeve is a firestop sealing solution designed for several types of plastic pipe and hard non-metal conduit installations. It provides reliable protection for penetrations by expanding when exposed to fire to help seal openings and prevent the spread of flames, smoke, and hot gases.

Ideal for flammable pipes penetrating uneven concrete fluted deck assemblies, Metacaulk Intumescent Sleeve is designed for concrete floor, wall, and fluted deck applications. In approved systems, it eliminates the need to firestop both sides of the penetration and provides an immediate smoke seal when used with Biostop 500+/150+.
