*  The thermal performance of ISOGARD polyiso insulation is up to 40% better than major competitors when tested by an independent third party in cold temperature 40°F (4°C) applications according to ASTM C1289 standards. The increased R-value per inch means better thermal performance from the same roofing systems using the same amount of insulation compared to leading competitive products on the market today.

**  Potential savings are only estimates; actual performance attributes vary based on many factors, including specific building features like skylights, wall insulation, and HVAC performance. Energy savings were estimated using an industry-recognized tool adjusting insulation thermal performance at 40°F (4°C) and applying it to the number of heating days. Consult with a competent mechanical engineer and/or roofing professional for more tailored savings estimates.
