A wall cassette is a perfect material for quick wall development, mainly for industrial buildings and warehouses. Their biggest advantage is an easy assembly, multifunctional use and high durability of elements. A building can be easily insulated which allows for the use of comprehensive solutions for light building development. The whole construction is characterized by high rigidity, leak-tightness and low specific gravity of sheets. High aesthetic value of elevation and resistance to mechanical damages is an additional asset. Blachy Pruszyński produces cassettes from 500 mm to 600 mm wide. There are also cassettes with perforation, which are not only perfect for elevation, but also serve as sound absorbing elements used indoors. Perforated cassettes are often used in buildings, where there is high moisture level, like swimming pools. The product is accepted within the European Union and marked with CE symbol.
