What is a cost-effective wall assembly?
it seems a variation of this building question gets asked a lot so forgive me... i am building a 600 sq. ft. home in the Rocky Mountains of British Columbia where the building code calls for poly on the warm side of the insulation.
i would like to get as close to R-40 for the walls as economically as possible. Seeing that the received opinion around the GBA is the tandem of polyethylene sheeting and exterior rigid foam is not ideal, what do the builders on this site recommend? Larsen truss seems fairly labour-intensive and rigid foam is expensive... Is a double stud wall the answer?
