Is all sill paper/sill insulation compatible with pressure-treated sill?

[Klicka]

If I am to use a pressure-treated sill, can I freely choose sill paper/sill insulation or is there any that doesn't go well with pressure-treated wood?

 

[Åsa Lund]

Really hope you're not going to build a house to live in with such wood?! For storage, etc., it might be okay, otherwise not.

Not yet decided if I should use treated wood or not. Saw both a Norwegian and a Finnish video on YouTube where they built garages and the sill was treated (on top of concrete blocks, not near the ground).

Why not? There seems to be a prevailing misconception on this forum that treated wood causes odors and discomfort if used as a sill, etc.
Until the late 70s, pentachlorophenol was used in the impregnation, causing a nasty smell in houses with treated wood sills and crawl spaces. Pentachlorophenol is now banned.

You can use regular sill paper

If you feel the need to use pressure-treated sills, then you already have a risky construction from the start. It's better to address the root problem than to try to patch it with pressure-treated wood. It is suitable for terrace floors and stairs, not more.

If you feel the need to have pressure-treated timber, then you already have a risk structure from the start. It's better to address the root problem than to try to makeshift it with pressure-treated wood. It's suitable for deck floors and stairs, nothing more.

Do you have to have a risk structure just because you choose pressure-treated wood? If Klicka wants to use pressure-treated wood, I think he can do it without a problem even if it were a dwelling house.

There you are wrong, öringen...
You should avoid embedding materials with a lot of chemicals unnecessarily.
If you need wood to build a wooden wall, you should use as pure wood/building material as possible and ensure that it is given the right conditions to function properly without risk of decay, etc.

I would argue that pressure-treated wood poses a greater risk on a deck/patio where we and our children place our feet and hands every day during the summer than as a sill in a house wall.

On the terrace, you don't spend two-thirds of your life, and additionally, you have good ventilation that airs out any potential emissions.

and you also don't spend two-thirds of your life inside the wall in most cases, there is building plastic inside the sill that probably protects against any possible emissions.
but I would also never use treated wood in the sill!

 

[Åsa Lund]

and so thanks to the exhaust fan, there is negative pressure in the house. The fan draws the emissions from inside the outer wall into the house before they go out through the chimney

I said if you feel the need for pressure-treated wood, then you have a risk structure. I have to say that I'm a little surprised, I never thought I would ever have this discussion.

I agree with you there. But that there would be any problem or risks with using today's pressure-treated wood in the sill, I have yet to see any good explanations for here on the forum.
