Graphite EPS for High-R-Value Insulation

Enhanced EPS with superior R-value and thermal resistance

Epsilyte’s Graphite EPS from Duralyte® incorporates advanced graphite particles to enhance thermal performance, delivering higher R-values in thinner profiles without sacrificing structural integrity or moldability. By reflecting and absorbing radiant heat, this material improves energy efficiency while maintaining durability and versatility. Lightweight and reliable, Graphite EPS is ideal for insulation in residential, commercial, and industrial projects where superior thermal resistance and long-term performance are required.

What is Graphite EPS?

Epsilyte’s Graphite EPS from Duralyte® is engineered with finely dispersed graphite particles that reflect and absorb radiant heat, significantly increasing thermal insulation compared to standard EPS. This high-performance material is used in insulated panels, structural insulated panels (SIPs), and specialty thermal applications where maximizing R-value in thinner material is critical. Graphite EPS maintains dimensional stability, structural integrity, and moldability, providing a dependable solution for energy-efficient designs across construction and specialty applications.
