Dry-construction Jincheng polyurethane sandwich panels, reducing waste on the environment caused by pollution, color-coated steel material can be 100% recycled, other supporting materials may be most of the recovered polyurethane sandwich prices, in line with current environmental awareness; all green building materials to meet ecological requirements composite polyurethane sandwich panels, conducive to health. Comfort Color wall using energy-efficient system, with respiratory function, can regulate indoor air humidity; the roof of a ventilation function, can be formed between the internal air flow over the house of polyurethane sandwich panels, roof ensure internal ventilation and cooling requirements . Quickness all dry-construction, without environmental impact season. A 300 square meters around the building, only five workers 30 days to be completed from the foundation to the renovation of the entire process. On the panel to be divided into two types: metal and nonmetal two panel panel. Metal panels easy processing, can be made into a variety of shapes, but some cases of non-metallic panels with metal panels that fall effects, such as corrosion resistance, impact resistance and other aspects.
