Can I use rigid foam to insulate my house, or am I asking for trouble?
I want to build an energy efficient and comfortable home. My thought is to frame 2×4 walls with 3.5″ of rigid foam between the studs and then using a modified “Mooney wall” technique run 2×4’s horizontally on the exterior of those walls with another 1.5″ of rigid foam to complete the envelope.
I was looking at using metal siding and roofing.
My question is: Am I going to be effective using this concept or am I cooking up a recipe for moisture issues, mold and rot (basically a structural disaster)?
Any and all suggestions and ideas are gratefully accepted! Thanks a bunch! (~8
