EPS Blocks - GPS Blocks

NeoStar GPS Blocks are made with Neopor® GPS. Graphite Polystyrene insulation has strong R-values and the ability to slow movement of heat energy like never before. Neopor® GPS Blocks contain graphite which reflects radiant heat energy and increases insulation resistance to the flow of heat. Keeping cool air in or hot air, NeoStar is the ideal product and is perfect for moisture management. This unique graphite foam is the future of EPS.
