Tips for Selecting and Using Foam Insulation
Pick the appropriate foam insulation for the job at hand. Shake can well before applying. Use minimal-expanding Window-and-Door Foam to insulate around windows and doors. Apply the foam sparingly, allowing it to expand to fill the gaps. Use Gap-and-Crack Foam to fill spaces between the house foundation and mudsill. Spray foam insulation behind electrical boxes prior to insulating the walls with fiberglass batts. Use fire-block foam insulation to fill holes around pipes, electrical cables, and ducts. To insulate large areas, such as stud bays, use two-part polyurethane spray foam.
