Equipped with manual or motorised opening, they adapt to all needs. Moreschi insulated folding doors ensure maximum practicality and resistance for all activities, even those that require frequent passage. Moreschi's excellence is achieved through design carried out by professional technicians, the use of high quality materials for every detail, production carried out with innovative techniques and installation followed directly by specialised technicians. The BIFOLD DOORS is made up of 52 mm thick leaves with respective internal perimeter frames in 20/10 thick galvanised steel profile; the leaves are entirely covered with smooth or peeled sheets obtained through a continuous rolling process, in SENDZIMIR galvanised steel, followed by phosphating and the application of 5 Micron thick primer on both sides. On the external side is applied the finishing varnish with a thickness of 20 Micron. The surface thus obtained is completely smooth. The pre-painting offers, without any alteration, the resistance of 400 hours in a salt spray chamber; finally we prevent any scratches with the application of 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 by means of a press expansion process that ensures a high degree of thermal insulation.
