I am trying to determine the best way to insulate an A Frame that has exposed timber framing. The existing construction is
1. spruce log rafters
2. 2x6 T&G board sheathing
3. 2x3 studs parallel to rafters at 16" OC
4. 5/8" plywood
5. 30# felt paper
6. asphalt roof shingles
There is no insulation. We need to provide insulation for winterization. What is the best way to do this without touching the interior?
