Hello everyone, I just found your site and I hope someone can help me with a few questions. I recently purchased a small (15x25) log cabin in Maine. The cabin sits on a concrete slab and appears to made of left over log ends. They are the kind of logs that have a wide tongue on top and groove on the bottom, but the pieces are only about 3 feet long. Because the logs are so short, there are a lot of seems, a bit of settling and some air/water infiltration. I am considering caulking and chinking as much as possible and then covering the structure with Tyvek. I would then add 2x4s vertically at 2 foot intervals, fill those cavities with 1.75" Styrofoam insulation and cover that with pine slabs as siding. Does anyone see a problem with this?
