ThermalStar® E delivers everyday performance and exceptional value. Ideal for below-grade applications, it offers stable long-term R-value, reliable compressive strength, and excellent moisture resistance. Manufactured with up to 15% internal recycled content.
ThermalStar® X is engineered for extra strength and high thermal performance in demanding applications. Manufactured with 100% virgin EPS, it is ideal for use in below-grade assemblies where higher compressive strength is required. ThermalStar® X offers stable long-term R-value, excellent moisture resistance.
ThermalStar® X+ is engineered for extra strength and top-tier thermal performance in demanding applications. Its dual durable film facers enhance surface toughness and enable use as an air and water-resistive barrier (WRB). Made with 100% virgin EPS, it's ideal for below-grade assemblies requiring high compressive strength.
ThermalStar® G is a graphite-enhanced expanded polystyrene engineered for improved thermal performance. Its graphite-infused core increases R-value per inch, making it ideal for use in below-grade assemblies where energy efficiency and space optimization are key.
ThermalStar® G+ is engineered with enhanced thermal performance from its graphite-infused core for high R-value applications. Dual durable film facers increase surface toughness and enable use as an air and water-resistive barrier (WRB). It is ideal for below-grade assemblies where space is limited and thermal efficiency is critical.
