Diagonal Board Sheathing and Air Barriers
I’m kicking around the idea of using pine boards for wall sheathing in a new construction home due to the high cost of OSB and CDX. I’ll be placing several layers of recycled polyiso over it which I could tape as an air barrier. I’m concerned that this might not be the most durable option over the long haul (insects mainly, no termites though).
Any thoughts? I like the boards because they come from a mill 3 miles away but don’t want to cut a corner now just to run in to headaches down the road. The alternative would be taped OSB sheathing followed by polyiso.
