Spray foam info
Starting a new build (1 1/2 basement walkout), all 2x6 exterior walls w/ brick veneer in GA, CZ 3. Above grade, would like to do spray foam in 2x6 walls, 1/2" or 1" of rigid foam board on the exterior, and a 1" air gap. Will this require a housewrap or can I do without the rigid foam and go with a housewrap? Also, any recommendations about insulation strategies for the finished basement. Thanks!

Will positive pressure work to vent an attic (i.e., blowing air in)? Attics exhaust fans are a bad idea. But what about blowing air in (using positive pressure).
