Building Envelope

The building envelope refers to the external walls (including the basement walls), the attic insulation, windows, and doors. If any part of the building envelope has been breached, the comfort and energy-efficiency of a home may be seriously compromised.

The better the building envelope, the lower the heating and cooling costs, and the greater the comfort within the home.
