Product Description
3M™ Fire Block Sealant FB 136 is a one-component, non-combustible draft, smoke, and fireblocking sealant designed to resist high temperatures and smoke passage in non-rated construction. This durable sealant is used to seal interior construction voids around wires, pipes, HVAC ducts, and vents in wood or steel framed non-rated construction. Ready-to-use, FB 136 seals, fills, insulates, and bonds for non-rated residential and commercial construction.
