How to insulate an above-grade interior foundation wall and curb?
We have a concrete slab foundation. Plan to lay Delta-FL down on the floor with plywood and hardwood flooring on top. Problem is that there is an above grade concrete curb surrounding the floor that protrudes five inches above and about 2 to 3 inches out from the drywall on the walls.
There is also one wall where the concrete foundation wall is about 3 feet above the floor (above grade with a crawl space on the other side), Exterior moisture intrusion is not a problem.
We need to insulate the curb and wall but don't want to create a mold problem due to thermal differential. Also don't want the curb protruding any further into the room than necessary. Thought about rigid foam, but that requires fire proofing outer finish. Dry wall over the foam would be a bit delicate for a curb. Not sure if putting the Delta Fl over the curb and wall would be a good idea or not.
