Andy,

Solid hardwood on the basement floor is a no-no, not that I want it there anyway. What they call engineered hardwood flooring, 1/4" hardwood glued to 3/8" or 1/2" plywood backing is supposed to be OK, but I don't want to put any wood on the concrete. Any flooring with much insulating value would undermine the effect my radiant heating system. I could just lay vinyl flooring all over the basement, but I thought the pergo imatator looks nicer and would provide some footfall cushioning. Hadn't thought about it being noisy tho.
