DAP Touch 'n Foam FireBreak Flame Resistant Sealant

Other fireblock foams are available, but they merely meet minimum testing standards. Touch 'n Foam Firebreak is a flame-resistant all-purpose, Class 1 fire-retardant foam sealant that exceeds testing standards. Firebreak is self-extinguishing and works by eliminating oxygen flow in service penetrations, where fire spreads most quickly. Using Firebreak in these penetrations blocks air infiltration, which means fire will take longer to burn through to adjoining rooms, giving you valuable time to get to safety. * Meets UL 1715, UL94 V-O, ASTM 814 E-84 * Approved Fireblock Penetration Sealant * Fills & Seals Service Penetrations * UL Tested / Class 1 Foam
