Values guaranteed with steel sheets as thick as indicated. Spans l in metres, as a function of a uniformly distributed load P (kgf/m2 ), have been obtained from experimental data and calculated to provide a deflection limit: f< l /200 of the span and a minimum safety coefficient that complies with the UEAtc standards for insulated panels, which have been established and are implemented by primary European Certifying Organizations.

U value is Thermal Transmittance Coefficient expressed in Watt/m20C and Kcal/m2 h0 C
