About This Product

Product Info


This product seals, fills, insulates and bonds for non-rated residential and commercial construction. Ready-to-use, this fireblock foam is intended to resist the free passage of flame and by-products of combustion within a concealed space of a floor, ceiling or wall cavity – restricting the movement of air, fire and smoke. This foam is tested as a Type V commercial and residential fireblock to ASTM E 84 (modified) and acts as a draft stop to help reduce air infiltration. This ready-to-use product is heat-resistant (up to 240°F/115°C) and expands up to 200% in volume to effectively seal penetrations.
Warning: this product contains a chemical known to the State of California to cause cancer.
