High 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.

Continuous Insulation
  • By blocking thermal bridging, a polyiso continuous insulation system increases the overall thermal performance of a wall assembly and a building.
  • A polyiso continuous insulation system keeps energy and heat loss to a minimum, increasing the building’s energy efficiency and leading to lower monthly operating costs.

Fire Performance
  • Polyiso possesses a high level of inherent fire resistance when compared to other foam plastic insulations due to its unique structure of strong isocyanurate chemical bonds.
  • In 3 key fire tests - ASTM E84, NFPA 285 and NFPA 286/UL 1715 - polyiso performs exceptionally well.
