Neopor Plus is a construction grade, graphite enhanced polystyrene (GPS) rigid foam insulation. This next-generation product builds upon the Neopor
brand, and delivers the highest R-value performance with no LTTR loss. Neopor GPS is comprised of many small pockets of air within a polymer matrix containing graphite. The graphite reflects radiant heat energy like a mirror, increasing the material’s resistance to the flow of heat, or R-value.
