Insulating lower level...??
I have a lower level that is half in ground/half above. The framing has newer R-13 batt insulation. I have a bunch of 2" pink board insulation(polysomething??). I have a few options what to do to make best use of it..
1. Move the metal framing(see pic) to allow insulation between framing and concrete foundation. This will give me a good vapor barrier.
2. Cut the insulation to fit between metal studs.
3. Use the boards over the framing and batt insulation to give better R value?
4. Buy more boards and install insulation over metal studs and drywall over that?
5. Return the boards to HD and use the money elsewhere?
Couple things.. I'm on a tight budget. I've been told conflicting info on installing pink boards over kraft faced batt insulation? Covering concrete foundation... does it really help? Since it's insulated by the ground around the outside, do you gain much insulating inside?
Thank you all...
