Dual Density

Dual Density

Double-density moulded sintered expanded polystyrene (EPS) insulation panel, available in white and grey (graphite) EPS, to which a high impact laminated polystyrene film (HIPS) is coupled, obtained through a thermoforming process. The double density EPS moulding gives the panel impact sound absorption qualities. The thermoformed film makes it possible to create retaining knobs that guarantee rapid installation and safe locking of the piping; while improving the mechanical resistance of the system and consequently the walkability during construction phases, and acts as a vapour barrier in the operating phase. The film is also shaped on the perimeter edges in such a way as to allow adequate overlap and a solid connection between adjacent panels, ensuring optimal sealing during the installation of the panels and the casting of the screed.
