100mm Grey Polystyrene (Graphite) is a high quality expanded polystyrene (EPS) board enhanced with integrated graphite within its bead structure and of grey colour. The high-purity graphite particles integrated within the insulation beads reflects radiant heat and significantly improves insulation capability, providing up to 20% greater r-value than traditional white EPS of the same thickness. The rigid EPS closed-cell insulation traps air in pockets within each bead when formed. Air trapped in these pockets is a poor conductor of heat, and therefore slows down its transfer towards cooler air.
Grey Polystyrene (Graphite) boards have high-purity graphite particles infused into its cell structure that give it a reflective property and a distinctive dark grey colour. As radiant heat moves through graphite insulation, it reflects it hundreds of times, significantly slowing down the transfer of heat and making it more energy efficient.
Warm air always moves towards cold air, but in Grey Polystyrene (Graphite) boards. that path takes many twists and turns along the way, slowing down the heat transfer, keeping the premises warmer. This improves its thermal conductivity to 0.031 W/mK, an improvement over standard expanded polystyrene boards.
