Thickness of foamboard for bottom plate?


Hi,

I was wondering what thickness of foamboard should I put under the bottom plate in my basement? I was thinking 1" attached to the floor with foamboard adhesive.

If you use pressure treated wood there is no need for anything.
If your going with untreated wood use this.

There is no need for anything thicker under a bottom plate.
