Why Polyiso?

What is Polyiso INSULATION

Polyisocyanurate (polyiso) is a closed-cell, rigid foam board insulation consisting of a foam core sandwiched between two facers. The facers are composed of various organic and inorganic materials. It is used in over 70% of commercial and residential markets for both wall and roof applications.

How it Compares

POLYISO VS. XPS

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.

POLYISO VS. Mineral wool

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.
