I'm remodeling my attic in my bungalow. The way I want to do it is to leave the rafters exposed so I get a rustic loft look. What I did first was put wood strips up between the rafters then installed the flat foam insulation onto the wood strips so there was a expansion gap between the roof and the foam insulation. Then I put up the 3/4 drywall between the rafters.
Now I'm doing the taping on those inside corners of the drywall between the rafters. Because one side of the drywall mud and tape will be on the rafter when we get our extremely cold winter weather even though the attic will be heated can those rafters freeze and cause the corners to crack?
