Insulation: rock wool sandwich panel for noise reduction deliver significant role Caigangyanmian board prices, especially for a place designated by the flight. After the addition of roof Caigangyanmian board with rock wool roof, rain, hail on the roof of the building steel interior noise caused by the impact, but also significantly reduced. Through testing, according to UNI 8270/7 and ISO 717/82 standards, the choice of a density of 120kg / m & sup3; sandwich core material for rock wool, sound insulation RW = 29-30 dB can be achieved industrial plants, warehouses: Sandwich plates are mainly used in industrial plants, warehouses roof and facade. Past industrial plants to use more precast concrete roofing or asbestos. With the rapid spread of light steel construction Caigangyanmian plate, sandwich also known for its many significant advantages to replace the above-mentioned two kinds of material. At the same time providing better insulation effect, sandwich panels with the mature development of light steel Caigangyanmian board, light steel system can truly reflect the light, fast and efficient, flexible layout and a series of advantages, which in the current single-storey factory building has become the preferred solution. As for the multi-industrial plants, in addition to the roof top of houses can be sandwich panels, the exterior wall sandwich panels can also be used as a flexible arrangement, by caitu varied colors and shapes to beautify the exterior of the building purposes. For constant temperature and humidity requirements of industrial buildings, using thermal performance is superior to brick sandwich as the envelope material can be significant savings in operating costs after completion.
