Titebond X-Treme Fire Block Aerosol Foam 12oz Can #8541 | 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.
