3Mâ„¢ Fire Barrier Pillows are self-contained, intumescent products designed for use in through-penetration firestops, providing up to 3 hours of protection. This fire barrier pillow expands to form a hard char that tightly seals against flame spread, smoke and toxic gases. We also engineered this product to be re-enterable and re-useable for new or retrofit installations.Specifications:Standard Package: 24 per CaseApproval: UL
