Polyiso continues to be one of the most cost-effective, energy efficient and environmentally responsible insulation products available, delivering dependable year after year benefits.

All polyiso insulation uses an hydrocarbon-based blowing agent which has zero Ozone Depletion Potential (ODP) and virtually no Global Warming Potential (GWP). This blowing agent complies with the U.S. Environmental Protection Agency (U.S. EPA) and Canadian Environmental Protection Act (CEPA). Polyiso insulation is the answer to CFC and HCFC free specification requirements.

Inch for inch, polyiso has superior energy efficiency performance compared to other building insulation products. In fact, independent testing of polyiso’s thermal performance has proven its R-value exceeds that of other common insulating materials.

Because of its high R-value per inch—which is the measure of thermal resistance used to describe an insulating material’s effectiveness—less polyiso is needed to maintain the same R-value. This results in:

• Thinner walls and roofs with shorter fasteners.
• Less change in building dimensions to meet a determined R-value.
• Immediate cost savings through a reduction in materials and labor.
