3M Fire Barrier Ultra GS Wrap Strip - 2 in x 40 ft

The 3M Fire Barrier Ultra GS Wrap Strip provides a quick and cost-effective firestop solution for non-metallic and insulated pipe penetrations. Designed for use in fire-rated wall, floor, and floor/ceiling assemblies, this graphite-based intumescent material effectively blocks flame, heat, and toxic by-products of combustion. The flexible rolled strip is easy to handle and can be cut to size with common tools to fit irregular-shaped penetrations. Because the material is re-enterable, it helps save both time and money during future installations. This reliable firestop solution is tested up to 4 hours in accordance with ASTM E 814 (UL 1479) to ensure high-performance protection for your building supplies and heating and cooling systems.
