Weatherization

Air Sealing

Insulation works by blocking the flow of heat through a surface such as a wall or roof. But insulation does not necessarily block the movement of air. This is especially true when there are cracks, holes, or other gaps that can be found in a typical house. Think of insulation as a sweater — it can keep you warm when the air outside is cold, but it does not really block the wind. For that you need a windbreaker. Air sealing acts like a windbreaker.

Air leaks can make your home feel drafty and uncomfortable and place an unnecessary strain on heating and cooling equipment, which decreases their efficiency and raises your energy bills. Air leaks can also let in moisture that can warp and damage wood and lead to mold.

We use a variety of gaskets, caulks, tapes, foams, and other products to ensure all openings are sealed for good.
