At correct technology of installation of polycarbonate it is necessary to focus without fail a protective layer outside. Non-observance of this rule can lead to polycarbonate damage by ultra-violet beams and decrease its toughness and durability. The protective layer is determined by the packaging - labels and office icons are plotted on the part of the protective layer of polycarbonate panels on the package. After installation the original packing should be removed.Sheets should be mounted only vertically, otherwise it is possible amassment of a condensate in internal channels. It is possible to subject plates to a bend in a cold condition in a cross-section direction (i.e. when the arrow of a deflection is parallel to a direction of edges of rigidity). To bend polycarbonate sheets along edges of rigidity is inadmissible.
