OSI Quad 1866185 Window and Door Foam Sealant 21.1 oz

OSI QUAD Foam Window & Door Installation Foam 21.1 oz is a single component, minimal expansion and low pressure polyurethane foam packaged in a pressurized metal container. It is specifically designed for use with the OSI QUAD Window & Door System. It is dispensed in bead form for sealing gaps and cracks, holes, and voids around windows and doors, in most types of construction projects, and is tan in color. This sealant exhibits slight to moderate expansion during application and cures upon reaction with moisture to form a flexible, urethane foam. The closed cell structure of this material provides an R factor of 5 per inch of cured foam making it an efficient method for stopping air and moisture infiltration and expensive warm and cold air loss between windows and rough frames. OSI QUAD Foam will not warp or deform windows and doors. OSI QUAD Foam adheres to all types of building materials including wood, concrete, and drywall, and is compatible with asphalt and butyl flexible flashing.
