With a huge selection of polystyrene foam in the building materials market, the ideal choice is the products of the German company BASF — polystyrene Neoporol, which provides effective sound — and thermal insulation due to the addition of graphite particles. Graphite reflects thermal radiation, reducing thermal conductivity. The inclusion of graphite particles reduces the volumetric density of the material, as a result of polystyrene, Neoporol is twice as easier and 20% thinner. Thanks to innovative technologies for the manufacture of polystyrene, the Neoporol has a low moisture absorption coefficient and is not subject to mold and fungus. It has increased sound — and thermal insulation properties with a lower stove thickness, while maintaining the strength and shape.
