Rigid Foam Strips for Thermal Break
Hey everyone, got a new build planned early 2024 in Lake Conroe Texas. We are doing 2×6 framing up and down with 5/8 OSB sheathing. I wanted zip R but the cost are just too high for our budget so I was looking for info about taking the Dow blue board rigid foam insulation ripping it down to 2” strips and installing over studs before the OSB sheathing. Then planning on going with open cell spray foam in the cavities. The foam board would be the 3/4 sheets.
Just looking for a cost effective solution to get the thermal break and getting a good insulation package. Before the spray foam was planning on the Areobarrier to get a tight seal and a fluid applied on the exterior.
