Air sealing is best applied right after drywall is installed, but can be also be applied after framing inspection, and after the house is built

How long does air sealing take?

How long does Aerobarrier last?

Based on third-party lab tested, Aerobarrier can withstand a 50 year durability test with little or no degradation

What metrics will be measured during seal?

Home Tight uses a diagnostic system that measures tightness in ACH 50 and CFM before and after the seal, as well as percentage reduction in air leakage; also, equivalent leakage (in sq. in.) for pre and post seal is measured. Report for the seal can be generated and sent within day of seal
