Hi, my builder proposes the basement end wall (10 ft. high) to be framed and covered with stucco to match the concrete side walls. He says to frame it vs. using concrete may cost a couple of $thousand less. The basement will be uninsulated and unheated.
Problem is what to use for sheathing that doesn't offgas. That excludes OSB and regular plywood. DOW SIS? Marine grade plywood? Advantech? I guess the same goes for the unvented attic sheathing, but maybe not as much of a concern (blown-in FG there). Does anybody have any other suggestions? Thanks much.
