Polyiso Roof Insulation Payback

As climate-control costs skyrocket, facility managers are constantly on the lookout for ways to reduce utility bills without sacrificing the comfort of their workers or tenants. Polyisocyanurate, or polyiso, insulation is versatile, durable and offers a high level of thermal performance. A study conducted by the trade association of the Polyiso industry (PIMA), indicated that by installing new Polyiso, or increasing the thickness of the existing roof insulation, managers could significantly reduce energy costs. Polyiso pays for itself over time.

Polyiso Performance

When compared to other types of building insulation, Polyiso has the greatest R-value per inch, which translates into greater energy efficiency in a smaller space. Its high compressive strength allows Polyiso to maintain its shape when subjected to the weight of the roofing system. Additional Polyiso benefits include:

  • Superior performance in fire-rated tests
  • Increased moisture resistance
  • Long-term thermal resistance
  • Compatible with many types of chemicals and compounds
  • Lightweight
  • Faster installation

Polyiso remains stable over a wide range of temperature fluctuations. It maintains its integrity from a low of minus-100°F to a high of 250°F, making it a favorable choice no matter where the facility is located.

Environmental Payback

Polyiso contains EPA-approved blowing agents. When installed correctly, it provides decades of superior performance, reducing cradle-to-grave extraction and manufacturing needs. Because it features high energy savings and low carbon emissions, Polyiso has earned a positive Life Cycle Assessment (LCA) analysis. It can often be reused, and when it reaches the end of its lifecycle, it can be recycled, further reducing its carbon footprint.


Polyiso is compatible with single-ply roof systems and metal roofs. When properly installed, it is also appropriate for modified bitumen and built-up roofs. For the best results, choose a professional roofing company with a proven track record of installing Polyiso. While extremely resistant, Polyiso is not structural and additional design components are necessary if the roof will experience foot traffic. Special care must be taken to protect the insulation from the elements before and during installation. Like the installation of most commercial roofing systems, components and accessories, installing Polyiso is not a do-it-yourself project.
