   Morning Scott,

   Yours is an easy one.

   First, do put a 1" Styrofoam SM between the concrete and the stone veneer.

   Second, use SM baseclad, applied directly to the concrete, strap and finish in the conventional method. No VB required.

   Scott, I agree with Gabe that Styrofoam on the inside of the basement is the way to go. In my opinion, this is the ONLY way to insulate a concrete wall in a cold climate. If it is applied directly on the wall, I have never had a problem with any kind of condensation and I have done this at least a hundred times. Wood frame walls with insulation next to a concrete wall are asking for trouble.

   Something else to consider...4" is the bare minimum for a stoneledge unless you are using very small stone. I like 6" ledges myself when applying fieldstone. Make sure you leave yourself enough ledge for the type of stone you are using. You can set the brickties (stone ties) into the foundation as you pour it to save yourself some work later.

   Dear Gabe,

   I understand that VB means vapor barrier, but what is SM?

   *My understanding of Gabe's suggestion seems to be different than your understanding of it. Gabe said that the Styrofoam should be placed between the concrete and the stone veneer, not on the inside of the wall as you suggested. But as for your suggestion, do you think that insulating on the interior of a cold-climate foundation is preferable to insulating on the exterior side, regardless of whether there is a stone veneer?Scott

   Scott,

   Sorry I was on assignment, so I'm a little late getting back to you all.

   SM is blue coloured Styrofoam that is rigid and of higher density than the white beaded insulation.

   The insulation should be placed behind the stone veneer and the shelf should reflect this. (4" for the veneer, 1" air, 1" SM, remainder concrete.

   Now the Baseclad is also this same styrofoam and is installed on the inside of the foundation. Top to bottom.

   This particular SM has indentations to receive the strapping that is attached mechanically to the concrete. Then the Drywall is simply screwed to it.

   The reason for the double insulation is cost effectiveness. The upper exposed section requires more protection than the lower area that is already protected with ground cover.By having the 1" material on the outside, it helps to prevent the concrete from freeze thaw cycling during the winter. When installed it extends up the wall pass the floor rim board or joists and helps greatly with keeping this area protected from the cold.

   Hopes this clears up your questions.

   Scott: When I did mine I used 2" "Blue Board" on the outside of the foundation and standard 2x4 wall on the isside. I did stand the wall out from the concrete ~1" for an air space. Lived there for 10 years and never had a problem. Also a cold climate, Montana.

   I would like to make a full basement foundation that has an exterior stone veneer on the top 18". The stone would rest atop a 4" inset ledge that is cast into the foundation wall and would be visible above grade. Since I obviously wouldn't insulate this veneer section of the foundation from the exterior, I'm wondering what the best way to insulate the foundation as a whole would be. I know that some people insulate basements from the interior side, but I have concerns about an interior-insulated basement for here in Maine. Even if the exterior were perfectly waterproofed, I would be concerned about the potential for moisture from condensation getting trapped behind the insulation. Does anyone have a solution for this dilemma? My indirect question is about the soundness of insulating a cold-climate foundation from the interior side.
