Insulation and air sealing work hand in hand to make your building more energy efficient and comfortable.
For buildings over 8,000 square feet and below 100,000 square feet, the Sponsors of Mass Save offer custom incentives for upgrades, like:
- Adding thermal insulation to existing exterior walls and roofs/attics
- Adding weatherstripping around exterior doors and windows to improve thermal resistance and reduce air leaking around the perimeters of doors and windows
- Making air sealing improvements to exterior walls and roofs to identify and eliminate sources of air leakage.
