RE: RH in Concrete for Wood Floor with Vapor Membrane
Welcome Jim, nice to see you here.

I'm quite curious about setting RH% limits on the timber flooring itself for warranty specs, rather than just the adhesives or moisture barriers etc. Our peak industry body in AU is currently mulling over this issue now- what to stipulate as an acceptable lower level of RH for our timbers. Plus I'm assisting on spec sheets for some engineered boards.

So you are saying that you can warranty a solid hardwood against cupping and other moisture-related maladies below 75% ? What would you say about engineered boards and the slab RH- is it overly optimistic to say they are extremely stable on moisture uptake than solid or is that like asking "how long is a piece of string"?
