I am looking for user experience with a sub floor material made from
recycled foam. I found it available from the following two sources:
in Canada at:
http://www.3rfoam.com/allinone_hf/index.html
In USA at:
http://www.3rdfoam.com/product.html
I'm not sure if they are connected or simply one company is a copy-cat
of the other. Anyhow, it seems like a good product and the sample
piece I have seems OK. But I can not find any recommended methods for
use as a basement sub floor. I.e. should I apply plywood over top?
How thick? Can I install laminate without the plywood? Should I
include a separate vapor barrier under or over top?
My house was built in '67 and the basement floor currently has a glued
carpet over top (which is getting ripped out).
Anyone with experience or recommendations would be appreciated.

IMHO, unless I misunderstand what they are selling, it is not
appropriate for a floor. You don't mention what you are putting on the
floor (carpet, hardwood, softwood, or one of the laminates) but that
will also make a difference.
What I do with basement floors is to lay a grid of 2x4 (flat side
down, so height is 2" (1.5 really). Then fill in the grid with rigid
building foam insulation. If the floor is wet, then all bets are off
of corse, and as well, I usually put in a couple of 'monitoring' holes
(in closets, or other out of the way areas) to allow checking for
moisture on the slab as time goes on.
On top of the gridwork, I lay sub-flooring and usually carpet. A
*really dry* basement could be done with hardwood or other material,
but most are not dry enough. I'd be happy to try to get a picture of a
neighbor's basement floor which looks dry, but when they laied
laminate on it, the laminate failed in about 4 years.

I have done this method in garage floors to convert to family rooms...
I put down first a good water based concrete seal.........
Then I use a roll of weather guard roofing material....overlap.
On that if there is enough room , I put in sleepers 2x4 p.t.lumber....flat
or upright......then fill with hard foam insulation.....I do leave an air
space if possible for ventilation between subfloor ply and insulation.....If
no space.....I just do a tight fit....
never have had a problem with moisture or mold.....

Sounds almost exactly like what I do, except I use 8 mil plastic
(never thought about using weather guard roofing material, and will
give that some serious thought the next time around!) I have always
done the sleepers flat because there never seems to be enough head
room in basements! I guess a garage conversion may have better
headroom, however.

Hi
In this one case there was room to put the sleepers upright. I like the
weatherguard since it is tough, and one side has silica on it and the other
sticks to anything....the overlap works well.
I like the vent idea.....and put some "bird holes" inbetween the
weatherguard and ply.....keeps things airy....
never any troubles with this........and it is in a moist enviornment
