foam board on south walls only?
My building orients north/south, meaning only one gable end faces south. Plans call for 2x6 walls sheathed with 1/2 OSB followed by Tyvek wrap. It will be bricked. I hope to use some closed cell foam inside but fiberglass batts will do the bulk of the insulating.
I read alot of talk on this forum about "thermal bridging" and if I gather correctly the solution is often "foam board". I brought this up to my builder and he seemed dismissive. I am on a budget, pretty much spent my wad on all the brick and the insistence on 2x6 walls on 16" centers with hurricane straps and simpson ties... on every 2x6.
I live near the Gulf of Mexico and it is hot and sunny. Should I insist on foam board on the south gable end?
