Insulated and ventilated multi-layered Deck Panel consisting of:

(1) Covering element in metal sheets, CE marked according to UNI EN 14782, consisting of a structural galvanized steel sheet (EN 10346) with a thickness of 0.50 mm (or 0.40 mm) protected in the upper face by an anticorrosive and soundproofing thermoplastic coating (about 1.5 mm thick) and a natural aluminum foil (or pre-painted aluminum), and in the lower face by a bituminous primer and a natural aluminum foil. To ensure the stability of the performance characteristics over time, the protection with an anticorrosive and soundproofing function, of a thickness of about 1.5 mm, must be positioned on the extrados of the sheet.

(2) Shaped insulating element in sintered expanded polystyrene with improved lambda closed cells containing graphite (reaction to fire Euroclass E, EPS 100);

3) Internal coating with centesimal foil in Embossed Aluminum (centesimal foil in Aluminum-Polyester).

The covering element (1) and the inner lining (3) have a continuous transversal marking. The covering element (1) must project at least 5 cm into the eaves in order to protect the head of the insulating panel (2); between the covering element (1) and the insulating layer (2) there are ventilation channels that allow free air circulation. The micro-ventilation of the panel reduces the thermal load to the extrados of the insulation, improving the internal environmental comfort, moreover it avoids the excessive overheating of the covering determining for the insulation and for the upper slab some more favorable working conditions for one of them reliability over time.

The panel is able to be bent on site on curved structures
