*  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. L’augmentation de la valeur R par pouce signifie une meilleure performance thermique par les mêmes systèmes de toiture utilisant la même quantité d’isolation que les produits concurrents les plus populaires sur le marché actuel.

**  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.
