The outstanding insulating efficiency of materials made of Neopor® Plus GPS (Graphite Polystyrene) foam gives engineers and processors decisive advantages in construction projects. Compared with conventional EPS, Neopor® Plus materials help streamline structures through improved insulating results. Infrared absorbers and reflectors greatly reduce thermal conductivity, lowering permeability of radiant heat and providing up to 20% higher insulating effect than conventional EPS panels. Insulating materials made of Neopor® Plus offer a higher insulating capacity using less material. They are easy on the environment and on the wallet.

Neopor® Plus increases its R-value in lower temperatures
