protectivewaterproofinsulated

One part, rapid, moisture-curing expanding polyurethane foam which is gun applied and has excellent elasticity, air tightness and acoustic properties. Excellent adhesion to brick, block, stone, plaster and cementitious materials as well as wood, metal and a variety of plastics. The low post-expansion facilitates greater control during application. Usage/Purpose For Interior and Exterior Use FM330 is ideal for use as an air tight gap filler for general construction joints, including where movement is expected to occur. It is suitable for applications such as airtight window and door perimeter joint seals, sealing floor to wall and wall to ceiling joints and pipe and service penetrations. Unlike most PU foams, FM330 can be used in temperatures as low as -3°C.
