I have a question about insulating a stud cavity. Typical 2 x 6 wall(or 2 x 4) cavity with studs 24" OC.
If I spray foam(using great stuff or similar) the vertical and horizontal seams where the stud meets the exterior sheeting then install a piece of blue foam by pressing it into the wet spray foam will I get a good seal? I think this would be less expensive than spray foam but haven't actually compared the costs yet. Is this a reasonable way to insulate? This would be for a stand alone building, maybe 24' x 16', used a studio or office space. Climate is zone 2, hot and humid.
