Polyiso Commercial Roofing Insulation with Maximum R-Values and More

Polyiso roofing insulation is a rigid foam insulation board made with continuous closed-cell construction that resists penetration by both air and moisture. When sandwiched between two facers, Polyiso insulation provides superior thermal protection and weather resistance. Polyiso roofing insulation is known for:

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

Polyiso roofing insulation possesses superior fire resistance: FM Class 1 Approvals (FM 4450/4470), UL 1256, CAN/ULC S126M and NFPA 285. Polyiso forms a protective char layer instead of melting in fire or intense heat, which reduces the risk of fires spreading from dripping material.

Contact the Carolina Atlantic distribution center near you across the South, and ask a team member for more information about Polyiso roofing insulation. We offer product help, financing options and can work with you on delivery timelines to keep you well-supplied for local roofing and building clients.
