We have a brand new home in the midwest and I want to start finishing the basement. It is a ranch with a walkout basement. Most of the area to be finished is above grade. The builder installed this blanket insulation on all the perimeter walls. Its basically fiberglass right on the poured concrete foundation with a vinyl face and its nailed right into the foundation every few feet.
My question is can I frame right up against that? I've read the building science article and I know the "ideal" solution is to tear it all out, put up XPS, frame, then insulate, but I'd hate to waste all this insulation. Another thing is our neighbor had the same situation, hired a contractor, and he just framed right up against it.
