Existing basement framing against concrete
We are looking to insulate our concrete basement foundation walls and the 18″ wood framed area between the foundation top and the bottom of the floor above it that includes the sill plate. We are settling on closed cell spray foam.
When the house was built the framing for the exterior basement walls were set up against the concrete foundation. There is anywhere between 0 to 1/4″ between the studs and the concrete depending on the studs and the texture of the concrete forms.
I understand that ideally there should be a 1-2″ gap between the concrete and studs, but it just isn’t there. In order to do so we would have to cut out what exists and reframe it. Some of it is either load bearing or will interfere with load bearing interior walls.
If we sprayfoam it as it is, are we asking for trouble?
