Polyiso HD cover board to insulate a basement floor

I need every inch of height on my basement ceiling, so I was wondering if either 1 or 2 layers of roofing type polyiso HD cover board would work as both the insulation and sub-tile floor? A couple of companies make such cover board and both claim an R value of 2.5 for only 1/2" thickness. All input is appreciated.
