31 maj 2023 · Easy to install, polyisocyanurate (polyiso) exterior wall insulation provides cost-effective, high-performing closed-cell, rigid foam continuous insulation in various types, sizes, and thicknesses to accommodate the specific needs of your project.
Polyiso insulation, a thermoset material, stays intact during the fire exposure and successfully performs by forming a protective char layer and remaining in place during the tunnel test, meeting the necessary ratings prescribed by building codes.
In summary, polyisocyanurate (PIR) is a high-performance insulating material that has seen widespread adoption in various industries, from construction to aerospace. Its superior thermal performance, fire resistance, and moisture resistance make it a versatile choice for an array of applications.
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.
Polyiso is a rigid foam insulation used in over 70% of commercial roof construction, in commercial sidewall construction and in residential construction. The Benefits of using Polyiso include: • Low environmental impact • Virtually no global warming potential • Zero ozone depletion potential • Cost effective, optimized energy performance
Polyiso insulation is an ideal choice for LEED building designs because it offers these advantages: • Highest Thermal Efficiency Polyiso is one of the most thermally efficient rigid foam insulations available in the marketplace, as determined using the LTTR testing
Polyisocyanurate (polyiso) is a cellular closed-cell rigid foam plastic insulation. The polyiso wall insulation boards consist of a foam core sandwiched between two facers (top and bottom). The foam core is comprised of a thermoset polymer that hardens by curing from a viscous liquid prepolymer.
