Rock wool board is mainly used for building insulation, including wall insulation, roof insulation, door insulation and ground insulation. Among them, wall insulation is the most important, which can be used in two forms: on-site composite wall and factory prefabricated composite wall.
One of the former is insulation inside the external wall, that is, the outer layer uses brick wall, reinforced concrete wall, glass curtain wall or metal plate, the middle is the air layer and rock wool layer, the inner side uses paper plasterboard. Another is external wall insulation, that is, in the outer layer of the building affixed with rock wool layer, and then add the outer decoration layer, its advantage is not to affect the use of the building area.
The external insulation layer is completely closed, basically eliminating the phenomenon of hot and cold bridge, thermal insulation performance is better than the external insulation. The factory prefabricated composite wall is a variety of rock wool sandwich composite board. The popularization of rock wool composite wall is of great significance to the building energy saving in cold areas of north China.
Because rock wool board has excellent thermal insulation, compared with EPS foam, it also has better fire protection function, which is very suitable for the thermal insulation of construction and industrial equipment, pipes, containers and various kilns. Building insulation, namely to prevent heat loss in winter and heat gain in summer, is the biggest application field of rock wool board
