In regard to my new built garage with 2X4 walls. Can I use that ½" pink Foamular insulation on the INSIDE of my walls if it's covered with sheetrock? I see it's for use on exterior walls, usually on the outside but how about the inside. Seems I could add some more R value, plus it would be a vapor barrier. (You'd think you would NOT want a vapor barrier on the outside of the wall) A guy down the block has some. Really bargain priced. Hate to pass it up if I can use it. Thanks.
