How do you attach strapping at the corners for 4″ of exterior rigid insulation?
Our firm is developing a range of sustainable wall section details for our clients to select from. For several variations, we have 4″ of rigid polyisocyanurate foam outside the structure. Along the walls, screws through 1×4 strapping fix the foam back to the studs. At the corners, however, this becomes difficult. What do you suggest? Any clarification would be helpful.
