This high-density Iso product incorporates several next generation features that result in a lightweight, yet extremely strong roof insulation.
HD Iso combines a specially coated inorganic fiberglass facer and a high-density foam core to create a cover board that has all of the characteristics you want in an insulation. No other single cover boards can match HD Iso's impact resistance, energy savings, flame resistance, moisture resistance and ease of handling and installation.
