The rock wool composite board is made of high-quality glass wool and fiber cement board. Rock wool sandwich panels fully utilize the unique properties of rock wool core materials, and have good effects in fire prevention, insulation, sound insulation, and other aspects.
Rock wool composite board is suitable for fields with high fire resistance requirements. According to the "Fire Protection Code for Interior Decoration Design of Buildings", rock wool composite board is of Class A, with a service life of over 15 years and a temperature of up to 700 ° C. It can largely resist fire for 6 hours. Moreover, rock wool composite board is an environmentally friendly material and a good choice in the construction industry.
Rock wool composite board is mainly used for building insulation, including wall insulation, roof insulation, door insulation, ground insulation, etc. Among them, wall insulation is the main form, and on-site composite walls and factory prefabricated composite walls can be used.
One of the former is the internal insulation of the exterior wall. The outer layer of rock wool composite board is a brick wall, reinforced concrete wall, glass curtain wall or metal plate, with an air layer and rock wool layer in the middle, and a paper gypsum board on the inner side. Another method is external insulation of the exterior wall, which involves pasting a rock wool layer on the outer layer of the building and adding an external decorative layer. Its advantage is that it does not affect the usable area of the building. The external insulation layer is completely sealed, basically eliminating the phenomenon of cold and hot bridges, and the insulation performance is better than the internal insulation of the external wall.
The promotion of rock wool composite walls is of great significance for the construction of rock wool composite panels in China, especially in the cold regions of the north. Because rock wool has excellent thermal insulation performance, compared with rock wool, EPS foam also has good fire protection function, which is very suitable for thermal insulation of buildings and industrial equipment, pipelines, containers and various kilns. Building insulation, which prevents winter heat loss and summer heat gain, is a major application field of rock wool.
In addition, rock wool insulation boards are also widely used in equipment such as tanks, boilers, heat exchangers, and buildings with larger planar curvature radii, typically at a temperature of 600 ℃; It can also be used for insulation and fire protection of ship bulkheads and ceilings.
