The TECHNONICOL CARBON SOLID extruded foamed polystyrene is a thermal insulation material with uniformly distributed closed cells, which does not absorb water, does not swell and shrink, is chemical–resistant and is not subject to digestion. High resistibility allows to receive equal and simultaneously rigid base, and it essentially increases term of operation of the whole heat–insulating system. TECHNONICOL CARBON SOLID contains Nano particles graphite that reflect heat radiation.
