I am building a 600 sq foot cabin in US climate zone 5 with 2 by 6 wall construction. I have gotten a lot of great information from your web site and, as a result, the wall system from the outside in is 1.5 inches of XPS rigid foam insulation, housewrap, plywood. I am trying to decide what kind of insulation to use in the wall cavity.
A local insulation contractor recommended a 1.21lb hybrid foam that is 20% open cell and 80% closed cell. Has anyone ever heard of this hybrid foam? Any opinions about this product as insulation in the wall cavity and also insulation in the attic space between the rafters?
