Airsealing
Reducing air leakage for greater health, comfort, savings.
Take a tour of a Cozy Home Performance completed attic project:
Air sealing is the most cost-effective way to reduce your home energy consumption.
Stopping uncontrolled air flow through gaps and cracks in the thermal boundary is integral to a healthy and comfortable indoor environment. More energy is lost through air leakage than any other means. High quality air sealing is the first step to a quality insulation boundary.
