Commercial Roofing Insulation with Maximum R-Values and More

Polyiso roofing insulation is a rigid foam board insulation made of continuous closed cells that resist air and moisture penetration. This material is sandwiched between two facers for superior insulating and weather resistance. Polyiso roofing insulation offers the following benefits:

  • Highest R-Value per inch of commonly used insulations
  • Moisture-resistant foam core
  • Compatible with most solvents used in construction
  • CFC-Free
  • HCFC Free
  • Zero ozone-depletion potential
  • Excellent stability

Polyiso roofing insulation also has the added benefit of superior fire resistance in testing, including FM Class 1 Approvals (FM 4450/4470), UL 1256, CAN/ULC S126M and NFPA 285 testing. Polyiso is a thermoset material that forms a protective char layer instead of melting in fire or intense heat. This helps with thermal protection and reduces the potential for spreading damage from dripping.
