Hardwood floors on above slab insulated basement floor?
I have read a lot of documentation from this awesome website and used some of the info to insulate my basement gluing directly over the concrete a first layer of 0.75″ of XPS followed by another layer of 0.5″ of XPS in the other direction. I then tapcon’ed a layer of OSB 23/32″ above it. I do not know what’s under my slab besides a dimple mat that goes to a sump pump.
I’ve been in that house in Upstate NY for almost 3 years now and the sump pump container has always been dry. Likewise for the walls, everything dry.
I have added 2″ of XPS on the walls and then framed 2×4 with R15 Rockwool but my question is not for the walls 🙂
It is now time to add floors and would love hardwood ones, but everywhere I go they tell me, no hardwood for below grade.
I haven’t checked the relative humidity in my basement but would a high humidity be the only reason why folks don’t install hardwood floors in basements (they only buy engineered hardwood)?
Based on my explanation, can anyone see an issue putting hardwood floors?
