SANDWICH - Изолированная металлическая панель для крыши

Insulated metal panel for roof.‎ The SANDWICH roofing system is ideal for lightweight, well-insulated roofs, consisting of curved panels (6 metre radius), which can be walked on, composed of double pre-painted galvanised steel sheet (corrugated on the outside and micro-ribbed on the inside) with self-extinguishing rigid polyurethane foam in between (with a density of 40 kg/m3 and a minimum thickness of 40 mm).‎The result is excellent in terms of lightness, thermal and acoustic insulation, fire reaction, and ease of assembly, all of which translate into considerable savings in the overall economy of the prefabricated building.‎
