Civil and industrial roof system slope p ≥ 7% insulated with PUR and rockwool The FIREMET® ROOF panel is a self-supporting metal N ME T EC panel manufactured using a patented production system Metecno and designed for fire graded ROOFS of industrial and commercial buildings. It is made of a corrugated outside sheet and an inside micro ribbed sheet, insulated with foamed PUR and with a layer of rockwool with oriented fibers on the inside facing of the panel. The FIREMET® ROOF panel contains heat and fumes in case of fire within the building, thanks to a 20 mm-thick rockwool layer. The FIREMET® ROOF is rated B S1 DO according to the new European regulation where class S indicates fumes containment. FIREMET® ROOF panels, tested at the Instituto ZAG according to the EN 1365-2, and obtained the following results: FIREMET® ROOF 50 mm: REI 15 - RE 120 FIREMET® ROOF 80 mm: REI 30 - RE 120 and at the LAPI workshop, in compliance with Circular n° 81 dated 14/09/1961 obtaining the following results: FIREMET® ROOF 80 mm: REI 30 (roof) FIREMET® ROOF 80 mm: REI 30 - RE 60 (wall) Specifications SELF-SUPPORTING INSULATION METAL PANEL FOR ROOFING Composed of: Inside facing: Steel sheet according to UNI-EN 10326 standard Thickness: 0.4 mm Surface: microribbed, pre-painted standard MT133 METCOLOR® System Thermal insulation: Class 2 foamed PUR pursuant to Ministerial Decree of 26/06/1984 Class 0 rockwool pursuant to Ministerial Decree of 26/06/1984 PUR thickness: 30 / 40 / 60 / 80 mm Layer thickness: 20 mm Nominal thickness: 50 / 60 / 80 / 100 mm Standard size The standard width of the panels is 1000 mm but they can be custom-made upon request up to a maximum width of 15,500 mm. Outside facing: Steel sheet according to UNI-EN 10326 standard Thickness: 0.5 mm Surface: corrugated pre-painted standard METCOLOR® System. Outside steel sheet Rockwall layer Inside steel sheet Table of safe spans Values guaranteed with external face in steel, 0.5 mm thick, and internal face in steel, 0.4 mm thick. The spans l (m) as a function of a uniformly distributed overload p (daN/m2), have been obtained from load tests carried out in Metecno laboratories, and provide a deflection f ≤ l/200 with a safety coefficient that complies with the UEAtc standards for insulated panels, which have been established and are implemented by primary European Certifying Organizations. steel - steel
