Insulated and ventilated sound-absorbing panel with multilayer protection 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 closed cell sintered expanded polystyrene with improved lambda containing graphite (reaction to fire Euroclass E, EPS 100) with continuous longitudinal inserts in rock wool with non-oriented fibers density 70 kg / m3;


(3) micro-ribbed lower sheet in structural steel, galvanized and prepainted with RAL 9002 (EN 10169) color, microperforated band longitudinal, alternating with solid bands, thickness 0.40 mm (or 0.50).

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 ventilation of the panel reduces the thermal load to the extrados of the insulator, improving the internal environmental comfort, moreover it avoids the excessive overheating of the cover, determining for the insulation and for the upper slab operating conditions more favorable to their reliability over time.


The roofing system ensures the following performances:
