Air Sealing

Air Leak Control!

Attic insulation reduces heat transfer through your home’s ceiling to outside, but you need to also control air leakage to prevent home heat loss effectively.

AIR SEALING BEFORE INSTALLING INSULATION

Attics must be air sealed before installing insulation in the attic to help reduce air infiltration through cracks, gaps and holes and to assure the insulation will provide the maximum benefits.

Excessive air infiltrating through small gaps and crevices wastes approximately 25% of the typical home’s heating and cooling costs. In winter, cold air leaks into the home while heated air exits. In summer, hot outside air enters the home, bringing in unwanted humidity.
