What type of flooring
I’m building a new construction home in east Texas with concrete pier foundation. My subfloor on the main level is 1-1/8 t/g. I am beginning to decide on finishes and trying to pick out the best type of flooring. I originally planned to do a conditioned crawl space but do to budget constraints I ended up spraying ~3” of closed cell spray foam under the subfloor. Floor joist were not encapsulated. I plan to use an engineered wood for most of the house allowing the subfloor to still “breathe” a little. I feel like the floors needs to be something with higher permeability so moisture does not get trapped in subfloor. I want to put tile in the bathrooms and laundry room and considering a cement backer board then unsealed tile. Again my main concern is avoiding moisture becoming trapped. If I did a non-permeable flooring and moisture got between it and the closed cell foam somehow it could eventually destroy the subfloor. Any suggestions on best type of flooring for this design and best type of underlayment for tile in this scenario would be greatly appreciated.
