minimum exterior foam, climate zone 6
Outside of my wheelhouse to perform the calculations, currently do not have access to PHP.
Will function as a shop space, existing garage with shiplap siding/ sheathing and open stud bays. Our goal is to keep the stud bays open (no cavity insulation).
What’s the minimum thickness foam required to keep the shiplap warm? Not as concerned with energy savings as it’ll be a part time shop space. We’ll run an airgap over the foam.
