What is “air-sealing”?

Air-sealing is basically draft-stopping – we want to eliminate any air movement between the conditioned space and the outside. The benefits of doing this are numerous and you may read more about those here: blower door testing page. The methods and products we use to achieve greater air tightness in buildings are many, and may include sealing all penetrations to the attic, dense packing walls with cellulose insulation, or sealing the rim joist with 2-part foam. We may need to remove window casings to seal the gap at the rough opening, or even replace a window.
