DAE see a huge difference in their framing after switching from green treated to synthetic sill plates?
I built a deck last summer using green treated for the ledger and posts, and by spring it was already twisting and cracking... swapped over to those synthetic composite plates on a shed foundation this month and the fit is dead straight, no warping at all. Has anyone else noticed a longer term payoff with these, or am I just lucky so far?

Whoa hold on. You're mixing up two different things. Green treated lumber and synthetic sill plates aren't really in the same category. Treated lumber is for ground contact and moisture resistance, not for staying perfectly straight. It's gonna move and check no matter what you do. Sill plates are a whole different product made to stay flat and dimensionally stable. So it's not really a fair comparison. You're comparing apples to oranges basically.

Yeah the apples to oranges thing makes sense, but I had the same experience switching mine out and it's held up way better than any treated stuff I've used. Sometimes the right product for the job just works.

Green treated is fine for ground contact but expecting it to stay dead straight is asking too much, that stuff moves like crazy. Synthetic sill plates are a different beast altogether, I swapped mine on a garden shed two years ago and they haven't budged a millimeter. That stable fit during install is a good sign it'll last, does your shed have any weird load points that might test it?
