Hi...

We're thinking of putting one of those engineered wood floor systems
down in our basement (Easy-Lock at Lowes). In that area of the store,
they had samples of the flooring, and then they had 2 grades of vapor
barrier. The low end was basically just a sheet of plastic; the high
end was a sheet of plastic with some felt attached to make the floor
spongier. The latter bit puzzled me a little - if you really expect a
moisture problem, wouldn't the felt just trap it and become a mold
factory?

I used Mannington engineered wood. They had tow types of barrier, one for
above grade, one for on or below. The below grade was a poly sheet but had a
poly foam, not felt backing. My guess is that the stuff you saw had
specific uses. Try a real flooring store and you may have better guidance
and better materials. You can see what I used at www.mannigton.com
