Titebond WeatherMaster X-TREME Fireblock low pressure one-component polyurethane foam sealant is a moisture cured foam designed to seal, fill, bond and stop air infiltration in areas where a fireblock product is required. It has a recognizable orange color allowing inspectors to easily identify the use of an approved fireblock product for Type V residential construction. Due to its expansion characteristics, it is more effective than many traditional fireblocking materials for the blocking of flames and smoke in concealed penetrations, preventing flame spread from room to room and floor to floor.
Titebond WeatherMaster X-TREME Fireblock exceeds all of the following specifications: ASTM D1622; ASTM C518; ASTM E2178; ASTM D1621; ASTM 1623; ASTM D2126; GreenGuard UL and UL
