PROTECTIVE TREATMENTS FOR EXTERNAL SUPPORT AVAILABLE 

On request for external polyester coating, atoxic prepainted for food contact, silicone polyester, PVDF, thermoplastic Class A application of PVC plastic films or other films.

INSULATION THROUGH CONTINUOUS FOAMING PROCESS 

Polyurethane resins (PUR) and (not standard) polyisocianurate foams (PIR), 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 W/(mK)

INSIGHTS PIR FOAM 

On request is available in PIR foam version (polyisocyanurate), a particular polymeric structure that guarantees excellent characteristics of fire behavior. The entire range of ISOTECNICA panels has been certified in Class B-s2, d0 in compliance with UNI EN 13823 (SBI) * where, "B" expresses the quantity 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 the fumes and "d0" indicates the absolute absence of drops and/or inflamed particles. In last years, the SBI test has become a standard requirement in Europe for fire behavior of building materials. The new European standard for sandwich panels - UNI EN 14509 - uses the SBI system for fire classification purposes. ISOTECNICA is the only one in Italy to design light, highly insulating applications with unequaled fire reaction requirements. In many cases it can replace the rock wool panel considering its fire reaction characteristics combined with the very high thermal insulation power.
