Touch N Seal Gun Foam II Fire Blocking Foam is an ICC code complying fireblock penetration sealant suitable for Type V residential constructions. The bright orange color alerts building inspectors that this foam has been tested with modified ASTM-814 and UL-1715 and evaluated by ICC-ES (ESR-1926). Withstands flaming over twice as long as the leading competitor, lending crucial seconds to dangerous situations. Gun Foam II is not a firestop.
