Intumescent Firestop Collar System

UL-Listed Penetration Sealing for Fire-Rated Pipe Applications.

Our Intumescent Firestop Collar System is a high-performance fire protection solution used to seal combustible pipe penetrations through fire-rated walls and floors. Designed to expand under heat, these collars prevent flame, smoke, and toxic gas from breaching fire compartments — helping to maintain the structural integrity and fire resistance rating of industrial and commercial buildings.
