The advantages of metal Buildings are their economical, fast, stylish and counter earthquake construction and the possibility of future expansion The metallic frame is covered with polyurethane panels that ensure effective thermal insulation, roof lighting, side windows, industrial doors, gutters, special fittings, etc. The panels are composed of two steel plates, between which the polyurethane insulation is inserted. Their interconnection is simple with guaranteed waterproofing. In addition, they have a built-in foam plastic sponge, which ensures tightness against air and dust. Ecological polyurethane (freon-free), self-extinguishing, class B2 according to DIN 4102 and hygroscopic (95% closed cells, water absorption less than 3% by volume). Density: 40 kg/ cubic meters Thermal conductivity coefficient: λ=0,0l7 kcal/mh ° C
