   I asked a question regarding this issue in another topic "applying dryway to block and brick". I asked if you could use contruction adhesive to glue polystyrene foam to the wall and then glue the drywall to the foam. With a good adhesive I think this is possible but have no experiance with this technique. I hate furring strips because you need to use mechanical fasteners and they are definately not speedy. I suppose you could even carve out channels for electrical using shallow wall boxes for the outlets and switches.

   I did get a reply that said this technique is approved at Johns Hopkins U.

   I would also be very interested in seeing different techniques for insulating a similar basement on my house. Any comments about the glue and go technique.

   *I've had some experience with glueing polystyrene foam to concrete. Not alot, but there was some variety (dirt formed 1908 foundation wall and a new fish pond wall). I never had much luck with the bond. Even where I had a good smooth wall free of the usual bumps and niggles (rare for any concrete work) the glue never held well enough for vertical use without support. I Followed the glueing instructions to the letter, as well as any variation I could think. The glue stuck to the concrete and it stuck to the foam, but it just didn't have enough grab to keep the foam from falling off. I agree, I don't think this should be a problem with a good adhesive, but seems like the only adhesives compatible with foam just don't have the right stuff.Bracing the foam to hold it while the glue cures is no picnic and no more time saving than furring. Ultimately I ended up furring with PTW 2x lumber. Powder nailing in one case (I seem to be the only one who enjoys a chance to powder nail) and drilled lag bolts in the other. I don't think I'd trust adhesive alone.
