OSI Window & Door Foam is a minimal expansion, low-pressure polyurethane window and door foam. It is dispensed with an applicator gun and works with weather barriers to help keep air and water out around windows, doors, pipe penetrations, and joints. This low-pressure window and door foam will not warp or deform windows and doors, and adheres to all types of building materials, including wood, concrete, and drywall. Foam is tack free in 10 minutes and fully cured in 24 hours. It is also compatible with asphalt and butyl flexible flashing.

As part of a complete system to help protect the building envelope, OSI Window & Door Foam can help increase energy efficiency by keeping cooled and heated air in, and the outside climate out. It can also block water infiltration, to help protect against moisture-caused problems, including wood rot and mold.
