Insulation & Weatherization

Home insulation and weatherization work to tighten your home’s thermal envelope. The thermal envelope includes the roof, walls, windows and doors, insulation, caulking, and weather-stripping. These practices improve areas that separate the inside from the outside. Improper protection in these areas directly affects your house's heating and cooling loads and in turn, your energy costs. Using these practices will help to lower your utility bill as well as improve your home’s comfort and overall value.
