It is going to be interesting, and I hope no one gets hurt, to find out what the long term issues are going to be with the new corrosive PT.
I had a conversation with my HILTI rep the other day and he told me that the PT manufacturers recommend nothing less than 1/2″ lags or bolts. Iguess the theory being that it will take longer for the wood to corrode them.
I wonder how many framers, after they put down a new PT sill or anything else PT are using the correct resistant nails when nailing the subsequent pieces of framing or sheathing on to them.
Has anyone seen or used this paper thin copper that is laminated onto some sort of coated paper. It’s so thin it reminds me of the stuff people use to gold leaf picture frames. And it’s code compliant?
You can fill volumes with what inspectors or code writers don’t think about.
Time will tell.

I'm not a big fan of this new treated wood. I too suspect a major disaster with this stuff. As for me, I'm only using it on my mud sills [thanks for the reminder to watch out for other nails (sheathing, siding ...)]. I'm planning on building my deck with rough sawn white oak 2x8's for the framing; 6x6's or 8x8's for the posts; and 1x6 t&g for the decking. I can get the logs for $500/1000 bd ft (international scale) + a little sweat equity and I'm good to go. This will all get a natural finish. No more treated lumber for me [if I can help it]!
