When choosing rigid foam insulation, you have three main options: Polyisocyanurate: Known as polyiso for short, polyisocyanurate foam has the highest R-value per inch (R-6.5 to R-6.8) of any rigid insulation. This type of rigid foam usually comes with a reflective foil facing on both sides, so it can also serve as a radiant barrier.

Rigid Polyisocyanurate Thermal Insulation Board). As part of that standard, the products must meet R-value requirements presented as Long-Term Thermal Resistance (LTTR). As foam ages over time, air and blowing agents diffuse in and out of the foam structure, resulting in reduced R-value.

Polyiso has a high R-value per inch compared to other insulation products. Polyiso is unique in that the R-value increases with the thickness of the foam, so three inches of polyiso has a higher R-value per inch than two inches.
