All panels from our offer are made of sheet steel, continuously hot-dip galvanized [95% zinc, 5% aluminum]. The technical characteristics of the panel are harmonized with the standard SRPS EN 13241-1: 2011 which is identical to the European standard EN 13241-1: 2003.
Under normal conditions, the panels are resistant to biological influences – mold, fungi and mold. Formaldehyde is not used in their production and the panels are not considered harmful.
The acoustic characteristic of all types of panels is reflected in the sound insulation [Rw] of 25 dB. The panels have a thermal conductivity, or so-called U value, of 0.51 W / m²K.
The filling of all types of panels is made of Polyurethane [PUR] which does not contain HFC, CFC and HCFC compounds and as such has zero impact on the ozone layer, which makes it fully compliant with the protocols from Montreal and Kyoto. It is environmentally sustainable and has little impact on global warming [GWP].
Solid urethane foam has a density of about 38 kg / m2. According to tests performed in compliance with European standards, the panels are classified in Class 5 [1300 Pa] under wind load, air permeability is in Class 2 without windows, and with 3 windows in Class 1.
Resistance to water penetration is in Class 3 without windows, and in Class 2 with 3 windows. Thermal resistance U = 1.2 without windows, and with 3 windows U = 1.3 [with C profile at the bottom and sealing rubber at the top].
