What It's About:
The latest codes require air-tightness testing for good reason: air sealing, with proper ventilation, is the key to lower energy bills and better indoor air quality. But is it better to air seal from the inside or the outside? Should your air barrier be the house wrap, the sheathing or the drywall? And most important, whose job is it to do the air sealing? In this demonstration, we’ll answer all of these questions and more.
What You’ll See and Learn:
- How to seal at the mudsill
- How to air seal structural sheathing with sealants, gaskets and tape and how to do so from inside the house
- Which caulks and foams are best and where to use them
- Components for sealing mechanical penetrations
