External wall insulation rock wool board, also known as rock wool thermal insulation decorative board, is an inorganic fiber board made of basalt as the main raw material by high temperature melting. In June 1981, it was successfully tested as a new type of thermal insulation, flame retardant and sound-absorbing material.

     The external wall insulation rock wool board has the characteristics of light weight, low thermal conductivity, heat absorption and non-combustibility.
     Below is the introduction of key technical points of the installation and construction of the external wall insulation rock wool board
     1. Treatment of special parts such as outer wall thermal insulation rock wool board, doors and windows, corners and so on.
     In the process of laying the external wall insulation rock wool board, it should be laid from bottom to top and staggered in the horizontal direction. The inner and outer corners of the external wall insulation rock wool board cannot be straight and should be interlocked. For the treatment of the rock wool board on the outer wall of the window, it should not splice, but the entire outer rock wool board is cut into a cut perpendicular to the surface of the board.
     2. Correctly handle the connection between the insulation layer and the wall structure layer.
     In most cases, the insulation layer and the wall structure layer are fixed by expansion bolts. It should be noted that the anchoring depth of the expansion bolts into the wall must be greater than 25mm to ensure the strength of the outer external wall rock wool board. At least 6 expansion bolts are required for each external wall rock wool board.
     Above is the introduction of key technical points of the installation and construction of the external wall insulation rock wool board. Hope this ban bring you some help.
