Description

OSI Flameseal Fire, Smoke & Draft Stop Sealant is a non-flammable, latex based fire stopping sealant. This one component sealant is designed for use in both residential and commercial fire stopping applications. Developed to seal service penetrations and joints in fire separations and firewalls, it prevents the passage of flame, smoke and fumes under actual fire conditions of 1, 2, and 3 hour fire resistance rated systems. Adheres to wood, gypsum board, concrete, steel, copper, cast iron, and other common building materials. Lab tested and compatible with ABS, PVC, CPVC, PP, PE and PB plastic materials. Also compatible with all electrical wiring and telecommunication cables listed in the firestop system designs. It improves STC values and upgrades sound quality. OSI Flameseal utilizes a special waterborne technology that is both non-flammable and non-hazardous and cleans up easily with water. Once fully cured it is mold and mildew resistant.
