A better business climate starts with a well-insulated building. Increase comfort and energy savings with these simple tips:

  • Make sure all exterior walls, ceilings, roofs, and wall cavities are adequately insulated.
  • Common air leakage points to check and seal include:
    • The areas around plumbing, electrical, and duct work in exterior walls.
    • Any chases open to spaces like an attic.
    • Gaps between interior and exterior walls and ceiling sheetrock.
    • Any sheetrock areas, including between interior and exterior walls and where sheetrock is sealed to the subfloor.
    • Openings around windows.
    • Floors, including cantilevered floors and band joist areas in floor systems.
    • Kneewalls in cape-style structures.
    • Joints between existing buildings and additions or modular buildings.
  • Add a reflective roof coating which keeps your building cooler by absorbing less heat.
