GPS Insulation – Advanced Thermal Performance with Graphite Technology

Graphite Polystyrene (GPS) insulation boards offer next-generation thermal protection, combining the lightweight benefits of EPS with the advanced insulating power of graphite particles. Engineered for high-performance construction, GPS boards reduce heat transfer more effectively than standard EPS — making them ideal for energy-efficient and passive house builds.

Whether you're insulating walls, roofs, or below-grade areas, GPS insulation delivers:

Up to 20% better thermal performance than standard EPS (lower lambda value)
Lightweight, rigid panels for easy installation
Excellent moisture resistance for long-term durability
Ideal for EIFS, cavity walls, under-slab, and exterior insulation systems
Compatible with modern building codes, including NZEB and Passive House

Explore our range of GPS insulation boards in various thicknesses and compressive strengths — perfect for projects where performance, efficiency, and cost matter.
