FireBlock Insulating Foam Sealant

FireBlock Insulating Foam Sealant


GREAT STUFF™ Fireblock Insulating Foam Sealant is an easy way to provide fire protection by reducing air movement in your home. By sealing the annular space surrounding your pipes, cables and ducts, the rate and speed of flames, deadly gasses and toxic smoke are minimized. At the same time, it helps you conserve energy, reduce drafts and save on heating and cooling costs. GREAT STUFF™ Fireblock is a minimal expansion polyurethane insulating foam sealant that fills, seals and insulates gaps up to 1/2 inch. Like all GREAT STUFF™ products, it is polyurethane based and will not absorb water.
