Fire Barrier Products

Maintain fire safety in your facility and help prevent the spread of fire and smoke with these fire barrier products from Grainger. Many products have an intumescent material that expands rapidly when exposed to fire or high heat to quickly seal out fire and smoke. Choose from fire stop sealant, caulks, and putties suitable for use on cables, ducts, drywall, and concrete walls. Most sealants allow installation on vertical or overhead surfaces and are paintable. Our selection of firestop pipe collars and cast-in devices are designed for use with metal, plastic, and insulated pipe. Firestop pillows, sheets, and wraps are for pipes and ducts, with some pillows featuring strips that ease overhead installation. Composite sheets and fire stop mortar can fill large openings in concrete floors and walls. Firestop pass through devices include materials ideal for sealing cable pathways. Choose the fire stop products that meet your application with many featuring fire ratings up to 4 hr.
