This video helps to demonstrate the importance we place on air sealing. Before insulating, we tighten up the attic. Of course we also air seal elsewhere, and it’s part of many of the common household problems we can address. Basements and crawlspaces help a lot too. Windows and doors matter, but really focusing on the top—and the bottom— first, creates the greatest impact.
Drafty homes can be fixed, and not just for heating season! Air leakage happens year round and affects our comfort daily!
