REScheck Compliance Certificate
I used Demilec spray foam for a house I am building in Charlotte NC and we sprayed 5″ to 6″ in the rafters. When I asked about the issue of how many inches and why we wouldn’t do more they referenced a Rescheck Compliance Cert.(sent me a copy) and said 5 to 6″ was equal to about 22 to 24 rvalue. The house passed inspection at this 5 to 6″. I hear 2 different sides and not sure who is right.
