About this product
SpecSeal® Firestop Blocks are penetration firestop products resembling foam bricks. These intumescent urethane foam blocks are installed in openings by compressing and stacking into the opening in a brick-like fashion. The intumescent block expands in high temperatures to impede fire, smoke, and gas passage.
