The roof panels are produced by ISOLPACK with a bitumen felt membrane. On which can be applied others waterproofing membranes and different layers for the protection of the roof. Advanced ISOLPACK's DECK solutions are totally designed by ISOLPACK Research and Development Division. Kappa 5 Deck - Dimension: width mm 1000; length upon request from continuous production process. Thicknesses (S): mm 30-35-40-50-60-80-100-120 panels of non standard thicknesses can be supplied upon request previous agreement on minimum quantities. Supports: galvanized steel, galvanized prepainted or plastified steel; stainless steel. Flexible support: bitumen felt membrane (KAPPA 3 e KAPPA 5) - brown color. For its characteristic (waterproof) the bitumen is widely used in roofing. Insulation through continuous foaming process of polyurethane resins (PUR), density 39 ±2 Kg/m³. Declared value of thermal transmittance for a panel after 25 years of its installation, (Appendix C - EN 13165). Initial value of thermal conductivity: λ = 0.020. Protective treatments for external support available on request for external: polyester coating, atoxic pre-painted for food contact, silicone polyester, PVDF, thermoplastic Class A application of PVC plastic films or other films.
