　　◆ Product use

　　The products are widely used in roof of large workshop, power plant, commercial supermarket, hangar, exhibition hall, gymnasium, mobile communication room, cold storage, purification workshop, clean workshop system, warehouse and other buildings.

● The fireproof rock wool roof panel is connected with concealed nails, and the board surface is closely overlapped.

● The unique waterproof groove design can effectively prevent rainwater leakage and avoid cold bridge phenomenon.

● The 42mm wave crest height greatly improves the bearing capacity of roof slab. At the same time, it can effectively reduce the customer's construction cost, and the roof slope can reach 3%.

　　The product has low thermal conductivity, high use temperature, fireproof and non combustible, convenient construction

       ▲ Sealing performance: the assembly line production process is adopted for polyurethane side sealing glass wool sandwich panel, which makes use of the excellent waterproof property of polyurethane products, overcomes the shortcomings of glass fiber cotton easy to absorb water and deliquescence, and effectively prolongs the service life of the product in terms of physical properties.

　　▲ Aesthetic performance: the interface is designed according to European standards, with smooth and smooth appearance, flat and beautiful board surface, tight joints and reliable strength, which can effectively prevent the generation of cold and hot bridges.

　　▲ Good stiffness: the polyurethane side sealing glass wool roof panel sandwich material and two layers of steel plate are bonded to form a whole and work together. In addition, the upper surface of the roof panel is corrugated and molded. Its overall stiffness is far better than that of the field composite plate with profiled plate and rock wool (glass wool). After the sandwich panel is fixed with purlin through connectors, the overall stiffness of the roof is greatly improved, and the overall working performance of the roof is strengthened. When rock wool sandwich board is selected, the purlin distance can be larger, so the purlin amount can be saved by 1 / 3 ~ 2 / 3.

　　▲ Reasonable connection mode: the polyurethane side sealing glass wool roof panel adopts the concealed connection mode, which avoids the hidden danger of water leakage in the roof panel joint and saves the amount of accessories.

　　▲ The fixing method is firm and reasonable: Polyurethane side sealing glass wool roof panel is fixed with special M6 self tapping screw and purlin, which can effectively resist typhoon and other external forces. The self tapping screw is set at the wave crest position between the two board joints of the roof panel, and special waterproof structure is adopted to avoid the occurrence of thin waterproof weakness.

　　▲ Short installation period: Polyurethane side sealing glass wool roof panel can not only keep the surrounding environment clean and tidy without affecting the normal operation of other processes, but also greatly shorten the installation cycle of the board. The daily average installation area of rock wool sandwich panel is 600-800m2.

　　▲ Anti scratch protection: during the production of polyurethane side seal rock wool sandwich panel, polyethylene adhesive protective film can be pasted on the surface to avoid scratch or abrasion of steel plate surface coating during transportation and installation. The energy-saving effect is remarkable and the performance price ratio is very high. Glass wool insulation board has excellent fire protection, heat preservation and sound absorption performance. It is mainly used for thermal insulation and sound insulation of building walls and roofs, fire prevention and cooling of building partition walls, fire walls, fire doors and elevator shafts
