as some of you know, I've been piece-mealing the work needed in my basement where the exposed portion of the foundation tended to get frosty in cold weather. I've been putting up 1.5" and 2" XPS on these surfaces, and framing for walls interior of that. So far, it's going well, but a few choices I made may come back to haunt me...we'll see.
This question deals with the EXTERIOR of the same exposed foundation (poured concrete) on the N/NW side of the house. In the winter, this corner of the house is the coldest, and is a big reason my basement is colder than it should be. So I'm taking steps to insulate from the inside, but I want to do something on the outside as well. Options?
Would a 1" layer of XPS or other "foamboard" product work here? Just glue it to the exposed concrete? Would that actually do anything? What about an adhesive "wrap" of some sort that would at least act as a water/wind barrier? This side of the house takes most of the weather as well, and there are signs that the concrete is taking a beating (water mostly)...so some sort of barrier might help. This is the street-side of the house, so the solution would have to be something that could be made pretty.
I'm not looking to tackle this problem now, rather wait until this spring/summer.
