This graphite-enhanced, 100% closed-cell expanded polystyrene insulation board can be used in a variety of wall systems.
Compared with other rigid insulation products, Sto GPS Board provides several advantages. It is cut in thicknesses that align with ASHRAE 90.1 prescriptive continuous insulation requirements, optimizing economy while minimizing wall thickness. With an R-value per inch of 4.7 at 75°F, Sto GPS Board is comparable to extruded polystyrene products and much more thermally efficient than expanded polystyrene. Sto GPS Board does not contain fluorocarbon-blowing agents. As a result, it features low global warming potential (GWP) and zero ozone depletion potential (ODP) and is available in all 50 states.
“Sto GPS Board provides substantial benefits over other rigid insulation products,” explains Richard Martens, Sto Corp.’s Director of Business Development. “We are eager to get it in the hands of contractors and architects so they can see just how great it really is.”
