Sealing up a home’s building envelope is incredibly cost effective and energy efficient, which means you can save up money in the long run. To do so, the structure must be secure, air tight, and water tight. Components of the envelope includes walls, floors, doors, roofs, and windows. Not only is air sealing cost effective, it also can improve comfort as well as indoor air quality. Achieving a high level of air tightness can be difficult, as it requires more than just filling up visible holes!
