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. 

 

  • Quality Mark™ certified LTTR-values
  • High R-value per inch of thickness
  • Thinner walls and roofs with shorter fasteners
  • Excellent fire test performance
  • Extensive building code approvals
  • Preferred insurance ratings
  • Compatible with most roof and wall systems
  • Moisture resistance
  • Dimensional stability
  • Compressive strength

BENEFITS OF USING POLYISO

  • Low environmental impact
  • CFC, HCFC, HFC free blowing agent
    • Virtually no global warming potential
    • Zero ozone depletion potential
  • Cost effective, optimized energy performance
  • Long service life
  • Recyclable through reuse
  • Recycled content (amount varies by product)
  • Regional materials (nationwide production network)
  • Meets new continuous insulation (ci) standards

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.
