Rim Joist Spray Insulation



Your home lets in cold air during the winter and warm air during the summer, resulting in higher energy bills. Stopping air infiltration is the best defense against energy loss.

Unlike fiberglass, which is only a thermal barrier, the spray foam insulation creates both an air and vapor barrier at the Rim Joist. Moist air can filter through fiberglass creating condensation at the Rim Joist, which can eventually lead to mold and mildew problems.
