DuraLyte® Graphite EPS Insulation
Advanced insulation engineered for long-term performance and energy efficiency
DuraLyte® is Epsilyte’s graphite-enhanced polystyrene (GPS) insulation, purpose-built for demanding environments. By incorporating graphite particles that reflect and absorb radiant heat, DuraLyte® achieves a higher R-value than standard EPS—delivering consistent energy savings, enhanced occupant comfort, and reliable performance for more than 50 years.
Its durable formulation provides superior thermal resistance, minimizes thermal bridging, and supports long-term building integrity across residential, commercial, industrial, and agricultural applications. With its gray coloration to reduce visible dirt and staining during handling, DuraLyte® also improves jobsite efficiency and minimizes waste.
