Can you quantify the air leakage savings of spray-foamed above-grade walls vs. batt insulated?
We are looking to convince a client that it's worth it to spray foam their exterior walls and basement. Does anyone have quantifiable data that shows the ACH@50 difference between two houses. One insulated with conventional batts, and another with sprayfoam?
Perhaps you've done air leakage tests on similar homes with the two different techniques?
