DMS: Thanks for replying. Yes, the barns are at least 200 years old , some much older like the Dutch barns. They used the super dense old-growth trees for the frames and sills and I think that might have helped endure time. I did not know that pt does not last that long, but it does not surprise me. Buildings of modern society have crap craftsmanship and do not seem designed to endure time like the buildings of old. How long is pt expected to actually last??What to do ?? about building a structure(house) bigger than a tool shed, for which a building permit is needed, if you want to go without the "drugged" wood products like pt????It does not seem that there is an alternative to pt when framing to a masonry foundation???I have wondered whether placing a steel strip between the two would work?, but steel still sweats too, so it is unlikely. Steel is also quite expensive these days. If anyone knows of alternatives to pt for the wood to masonry interface, please let me know. Thanks. tb
