One of the floating HDF/Laminates with the recommended underlayment will

That is thinner than I have seen as a total height.
Do you know which one? Brand??

You could _probably_ get by with simply a layer of heavy paper if this
is above grade with finished floor underneath rather than bare crawl
space so there's really no moisture issue but as Leon says,
"manufacturer rulez" is the real answer.

Underneath of house is a heavy Polyethylene underbelly secured to
steel girders, above which is heavy insulation. It has a space to
crawl underneath the house but you can't reach much without removing
all of that poly and insulation. There are only secured spots where
pipes and wires come through for water, electric, etc.

I am still searching for a product, preferably DiY.

The above was the spec's from one of the multitude of lower-priced
products from Lumber Liquidators web site....I'd be pretty certain there
must be hundreds of very similar dimensions available. Which one it
was, specifically, I don't recall, but was one of the "clickable"
floating (not glued/stapled) styles.

Sounds as though should work just find for the application altho you'd
still want to double-check manufacturer's info for installation
guidelines and especially proscribed uses. Most are ok above grade;
it's below grade and/or directly on concrete that is the primary
moisture issue.

You don't give a location so can't judge what the climatology might be
as far as wetness factor...out here SW KS High Plains I'd have no
concern; back in coastal VA, say, well, would guess would want to not
skip the moisture barrier underlay...


Click Laminate flooring is available from 6mm to 15mm thick, with
quality from abyssmal to pretty darn good in pretty well any
thickness. Price is all over the map, and sadly just because you pay
more doesn't make one better than another. The european and north
american broduct are GENERALLY better than the Chinese product (as in
just about anything) There again, just because it has a european name,
and the head office is in Sweden or wherever, does't mean the product
isn't from China!!!
