With the coming of winter, the sales volume of rock wool color steel plate used for building thermal insulation housing has increased dramatically in such a season. With the appearance of new technology coating, sandwich board once used in winter has the effect of heat insulation and UV protection.Although Xiamen color steel plate has excellent fire-proof performance, in the early days of color steel plate popularity, the earliest sandwich plate is mainly used in winter, as one of the building materials for outer wall protection in the extremely cold places in the north, but in the south, the single-layer color steel plate is generally used to build the roof shed, but at that time, the building materials did not have the current anti-corrosion and heat insulation function, and in recent years, continuous experiments have been created. The thermal insulation coating, which is coated on the surface of the metal panel, can effectively heat and heat preservation. But in the south, the sandwich panel foam board is prone to fire under the high temperature sunlight, so the sandwich layer of the board will try to use natural rock to foam the ripening. Its heat insulation performance is outstanding, and its fire resistance is higher than that of the general sandwich panel. Because the pure natural core material is made of rock, and the natural stone material is incombustible, so that the fire resistance of the rock wool color steel plate reaches 100%. More and more people use it to build summer shelters in midsummer, which can ensure that the outdoor heat can not be invaded, and the indoor temperature Maintain a certain degree of comfort, so that indoor residents can not feel the heat of summer.
