This dropped ceiling above the shower was found to be connected to three open wall cavities. During a weatherization job in Clark County, McMahon discovered the home had no existing floor insulation and minimal attic insulation, making it an ideal situation to perform effective air sealing. He recognized the homeowner would benefit from a noticeable improvement in comfort, and also save money on their utility bill after the air sealing and insulation project was complete.

In the attic, they discovered many of the home’s interior walls were wide open on top, which allowed cold winter air to drop into the living space, making the home much more difficult to keep warm and maintain a comfortable temperature. The team’s air-sealing strategy was to effectively cap off the walls and insulate over the top to create a continuous blanket of insulation that retained the home’s heat. This comprehensive approach to weatherization satisfies customers through improved comfort, which means more referrals and less callbacks for contractors.
