I had an opportunity to purchase a couple of pallets of rigid foam insulation; tapered from .5 to 1" and with a fiberglass embedded facing on both sides. I believe it is polyiso.?
I realize this is for roofing applications but am wondering if I could reverse the tapers to each other to achieve a consistent 1.5", or more, and use it below grade to insulate the interior of a cement block basement.
