Firestop Foam

Firestop Foams are expanding, fire resistant spray foams that fill holes and voids to block the spread of smoke and flames in a potential fire. Boss 812 is a firestop foam insulation that blocks smoke and other toxic fumes from passing through penetrations in walls and floors. Boss 813 is one of the few fire-rated spray foams that meets the firestop code: ASTM E-814. Foam is a fire resistant foam that prevents the spread of fire, smoke and toxic gasses from one compartment to another, while still maintaining the integrity of the Firewall.
