Air sealing is preventing infiltration from outside air into your home. With aerobarrier, an air born sealant, the product finds tiny leaks in your home and plugs them to reduce the overall amount of air leakage.
This is measured in Air Change per Hour at 50 pascals. (ACH50). The higher the rating, the more the house leaks air. Average homes may leak at the rate of 15 ACH50, while Sutter Homes has recorded a 0.01 ACH50 home, one of the lowest ever recorded in the nation.
Using Aerobarrier and developing record-breaking ACH50 rated homes is one of the many integrated ways that Sutter Homes builds Zero Energy Ready Homes.
