On the external side is applied the finishing varnish with a thickness of 20 Micron. The surface thus obtained is completely smooth. This pre-painting offers, without any alteration, the resistance of 400 hours in a salt spray chamber. Finally, we prevent scratches by applying adhesive film to be removed after installation. The insulation is guaranteed by the injection of self-extinguishing polyurethane foam according to DIN 4102 class B2, with a density of not less than 43/45 kg/m³, obtained through an under-press expansion process that ensures a high degree of thermal insulation. The hinges are made of black painted aluminium alloy, with anti-slip pin and anti-unscrewing frontal stripes. They allow the door leaf to be adjusted even after installation.
