When your attic lacks the proper attic insulation and air sealing, the effects on your home’s comfort and energy efficiency are significant. An attic that doesn’t meet insulation standards will lead to high heating and cooling costs, uncomfortable rooms, and uneven temperatures throughout your home. In this application, considered the most effective, the foam is sprayed directly to the underside of the roof between the joists, down around the rim, and onto the top plate, on the gable end walls, effectively sealing off and insulating the entire attic space from any air infiltration.
