Default Pressure treated wood for interior framing?

Made the mistake of flipping channels at the first commercial break of Jeopardy last night.

Landed on one of the DIY channels with a show called "Renovation Realities". I've watched the show alot in the past and it had novices doing renovation projects. Hilarity ensued.

Last night's shows had Dale Earnhardt Jr. and his wife redoing a house in Key West. Like 4 episodes worth.

It appeared they were using pressure treated wood for interior framing. They didn't say it was that it was PT, just the color of it gave that impression. The whole show wasn't very technical, just glossing over start, midway and end product for different parts of the house.

Is that a Florida thing?

No. Not that I've ever heard of. That crap twists up like noodles and smells. Exterior use only as far I I'm concerned. Maybe a bathroom shower.

Sill plates that sit on slabs or foundations are often pressure treated lumber due to the contact with cement, which can wick moisture. Studs and top plates are not commonly PT, and as noted above, are prone to significant warping and twisting.

I think all new construction in Hawaii has to be pressure treated

Pressure treated anywhere in contact with masonry. Inside PT would be a terrible idea with all the chemicals in the wood off gassing inside the house.

It is very common in Florida. Most CBS houses use pt furring on the block walls and pt bottom plates on the interior walls (on slabs). I was from the northeast where no pt was allowed inside so this was a drastic change for me.

I would think PT for a shower or bathtub would be a fairly bad idea as tile/grout is not forgiving if there is any twist./warp,

Sounds kind of strange, pressure treated timber here is the same as "normal" construction timber, just a bit more expensive, no more twisting than any other material, you can buy a landscape quality which is much cheaper and can twist a bit out in the weather.

I would not have liked to live in a house with very old PT lumber as a lot of it was arsenic. Nowadays, the worst is just copper compounds, not quite that bad.

I'll try and get you a picture tomorrow of the stucco shed in the back yard of a house I just bought. Every piece of framing in it is PT, except for the 2x4's on the side of the door jam....well, what's left of them. Termites have eaten them down to nothing and no evidence of termites anywhere except the 2 non PT 2x4's.....they are being replaced with PT 2x4's. Termites in FL are a real issue. As stated above, PT furring strips as well on the concrete block. Alot of houses down here use PT trusses and structural framing, non PT on the inner walls....there are many inner walls studs that I've replaced due to being eaten by termites.

What is the problem with arsenic (CCA) as long as it is buried inside the wall? This whole thing came up with them making playground equipment from CCA and kids getting it on their hands and then in their mouth. I am not sure they ever proved anyone was hurt but the idea is pretty scary to parents. Unfortunately then they started thinking this stuff was plutonium and it was going to leap out and get you through the wall.The main problem with the newer replacements is you need special fasteners, hot dipped (not electro plate) galvanized or stainless to keep the copper from eating the steel.
Using a little common sense, there is nothing wrong with CCA. Just don't use it for your cutting board in the kitchen.

Not a problem outside, The topic is about using it inside. You do know hat the second C in CCA is also copper? And you do know that the first C is chromium, one of the deadliest metals. I don't want it but you can have it if you like...good luck with that.

I suppose you don't drink any water that travels through copper pipe.

and if you are eating food cooked in stainless steel -
guess you shouldn't look up what element constitutes >10% of it
(starts with a C)

And the third letter A in CCA is Arsenate. Yeah, I'd want my house full of a dangerous fungicide and pesticide. Sure, what could possibly go wrong?

The only interior wood that needs PT is wood that touches concrete. And those that say my house is built with PT....How about your roof trusses? That's over 50% of the wood in an average house.
