Green Building Design.

Insulation is the product found to provide the greatest return on investment and offer the most carbon abatement. Polyiso - which Forbes considers a “green” insulation, is an ideal choice for green building design.

What are the Environmental benefits of Polyiso insulation?

Reduced fossil fuel consumption

Well-insulated buildings reduce the need for energy, thereby reducing air pollution and greenhouse gas (GHG) emissions. BOMA currently represents roughly 9 billion square feet of roofing area. Reducing energy consumption by just 10 percent in these roofs is equal to planting 344,922,103 trees - a huge reduction in atmospheric CO2.

The planting of these trees would also :


Generate 10.7 Trillion Dollars of Oxygen


Provide 21.4 Trillion Dollars
Worth of Air Pollution Control


Recycle 12.9 Trillion Dollars

Worth of Water


Control 10.8 Trillion Dollars
Worth of Soil Erosion


The Equivalent of Removing 42.7 Million Cars off the Road for One Year

Highest thermal efficiency

Polyiso is the most thermally efficient insulation available in the marketplace, as determined using Long Term Thermal Resistance (LTTR) values, a 15 year time-weighted R-value. In addition, Rmax participates in a third party certification program - QualityMark - to validate these predicted thermal values. QualityMark is a voluntary program administered by FM Global, one of the nation’s most dependable testing organizations.

Zero Ozone Depletion Potential

Rmax manufactures rigid foam board with third-generation, zero ozone-depleting blowing agents. All Rmax Polyiso products are HCFC-free and CFC-free.

Zero global warming Potential

Rmax manufactures rigid foam board with third-generation, zero global warming potential blowing agents. This quality is critical as the impact of climate change is acknowledged as a worldwide environmental concern.

Recycled content

Virtually all Rmax Polyiso insulation is manufactured using recycled material and many facers contain up to 100% recycled materials.
