Sto GPS Board is a graphite-enhanced, 100% closed-cell expanded polystyrene insulation board that can be used in a variety of applications. It’s cut in thicknesses that align with ASHRAE 90.1 prescriptive continuous insulation requirements, optimizing economy while minimizing wall thickness.
It has an R-value per inch of 4.7 at 75 degrees F., which means it’s comparable to extruded polystyrene products and more thermally efficient than expanded polystyrene. It does not contain fluorocarbon-blowing agents and features low global warming potential (GWP) and zero ozone depletion potential (ODP).
