Product Description

ProBoard Ultra GPS (Graphite Polystyrene) foam board insulation delivers superior thermal performance in a thinner profile compared to standard EPS. The graphite infusion increases R-value per inch, making it ideal for space-constrained applications. Suitable for above-grade walls, below-grade foundations, and under-slab installations.
