HD and Lowe’s sell this product which I have pondered using for insulating the walls of our basement. It claims an R-12 rating and is supposed to be a blue styrofoam backed OSB board (2′ x 8′ x 2.475″ panels) price $7.19 ea. Directions call for attaching directly to concrete wall no studs required as there is a shiplap joint for supporting one panel to the next using a minumum of concrete screws. Sheetrock, beadboard or what ever siding is attached directly to the OSB. Claims not to cause sweating i.e. thermal blocking via the foam.
My question is, has anyone used this and what are your impressions. Favorable or unfavorable.

Actually, its OVRX Barricade using Dow foam.
That is correct. The web site is OVRX.com. Have you or do you know of anyone that has used the product and does it live up to their claims?
Thanks

If cuss has email notification checked in the profile, he will not know you made it. He'll just have to stumble upon the thread.
I ask because many new posters seem to be showing the same reply to themselves-curious if it's another glitch in this antiquated software.
thanks.
Well, I think most of us on this site are really just talking to ourselves anyway.
styrofoam
I would not use for this reason: it reintroduces lot of organic material for the mold, that is the osb sheathing. My basement's problem was not sweating but more the musty smell created by the mold that was living in the fiber insulation and sheetrock. Everything was removed and replaced with blue insulation sheets and paperless sheetrock. I still use dehumidifier in summers because there are other things that mold can grow on, just not so well.
I glued the foam sheets to the wall to hold them. Then 1x3 furring strips every 24" with tapcon screws over the sheets then finish with paperless sheetrock. I put one switch and 2 outlets on that wall with wiremold.
The tops of the foundation were also covered with foam sheets and every joint sealed with expanding foam from the can, so that the concrete foundation was encased. There is nothing you can do about the sill plates, joists, etc.
Support for this kind of panel may come from people who put wood floor over concrete using foam boards and plywood. I have no experience there. I think the way I finished my foundation wall is working because I had some cardboard boxes leaning on that wall for 2 summers without musty smell coming from the boxes. Dehumidifier was used, with about 1 gal to be emptied about every 4 days. The foam boards were 1" blue boards from Lowes. Hope it helps.
I think that's the point of the foam - to be a barrier to moisture infiltration. You would have to seal the floor up too.
