Alfa 1 - Dimensions: width 1000 mm, length as requested in continuous production. Standard thickness of polyurethane out of ridge (S): Panels with non-standard thickness (mm max. 200) are available on request, subject to agreement on minimum quantities. Foam insulation in continuous ofpolyurethane resins (PUR) or (PIR to request, non-standard) . Density at the heart PUR: 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 availableon 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. Alfa1, upon simple request is available in PIR foam (polyisocyanurate rigid foam), a special polymer structure that provides excellent fire behavior. The entire range of panels ISOLPACK, was certified Class B-s2, d0 at the CSTB (France) and at the KIT (Germany) in accordance with UNI EN 13823 (SBI)*, where "B" expresses the amount of heat produced during the first 600 seconds of the test <7.5 MJ (best value obtainable for foamed products); "s2" represents a very low development of smoke and "d0" indicates complete absence of drops and / or particles inflamed. In recent years, the SBI test has become a standard requirement in Europe for the fire behavior of building materials.
