Air Sealing

Why You Should Air Seal Your Home

Air Sealing is a cost-effective way to cut heating and cooling costs. It reduces the amount of air leaks for your home, which improves durability, increases comfort, and creates a healthier environment in your home. Additionally, sealing cracks/openings reduces drafts and cold spots, improving comfort. We recommend reducing air leakage as much as possible and providing controlled ventilation as needed.

Types of Air Sealing

A couple of air sealing techniques include caulking and weather-stripping, which are both simple and effective. Caulk is used for cracks/openings in or around window frames, door frames, and other fixed

constituents . Weather-stripping is used to seal components that move, such as doors and operable windows. Closed-cell foam blocks air fairly well, and is one of the best ways to seal band joists. It's typically used in wall and ceiling cavities (openings/awkward spaces).

*Please note: Air Sealing by itself doesn't remove the need to proper insulation. It does not reduce heat loss and air infiltration alone.
