Sto GPS Board is a graphite-enhanced, 100% closed-cell expanded polystyrene insulation board that can be used in many applications, including the StoTherm ci GPS wall system. The board is cut in thicknesses that align with ASHRAE 90.1 prescriptive continuous insulation requirements to optimize economy and minimize wall thickness.
Featuring an R-value of 4.7 per inch at 75 degrees F., Sto GPS Board is comparable to extruded polystyrene products and more thermally efficient than expanded polystyrene. It does not contain fluorocarbon-blowing agents, so it has low global warming potential (GWP) and zero ozone depletion potential (ODP).
