2" Poly ISO Roof Insulation Board Flat 20 PSI R-Value 11.4 4X8
Polyiso Insulation is made of glass fiber-reinforced cellulosic felt facers bonded to a core of polyisocyanurate foam. When properly installed, it is suitable for use under built-up, modified bitumen, and most single-ply roofing systems. Studies have shown that insulation is one of the quickest and easiest ways to improve the energy efficiency of a building. Polyiso Insulation provides one of the highest insulation R-values, compared to any other type of insulation of equal thickness, which makes them the best solution.

Benefits of Polyiso Foam Insulation include:
- Lighter than most insulating products offering comparable thermal resistance; up to 5x lighter in weight than other materials with the same R-value.
- High moisture resistance and no capillarity; is stable and maintains its physical and insulating characteristics
- Easier cutting in the field provides the installer with simplified fabricating on the roof deck, which minimizes on-the-job damage
Polyiso Insulation is designed for use over structural roof decks where R-values of 5.7 or higher are required, along with comprehensive UL and FM approvals
