External insulation rock wool board is a rock wool board for external wall thermal insulation. It is class A non-combustible fireproof thermal insulation material. It has high compressive and tensile strength, low water and moisture absorption, good dimensional stability, good aging resistance and doesn’t have thermal expansion or contraction. It is compatible with the external wall system, and provides effective heat preservation and energy saving, fire prevention and extreme weather protection for the building.

     Construction process of external insulation rock wool board
     1.1. External wall primary treatment
     First, use a shovel to clean the floating dust and weathering on the surface of the external wall. The surface should be solid and flat. If the external wall is aerated concrete block wall, it is necessary to spray interface agent on the surface of the wall first, level it with cement mortar, and sweep the surface. The joints between the wall and the concrete beams and columns should be smoothed with polymer mortar first, and galvanized steel wire mesh or alkali-resistant fiber mesh should be added to enhance it.
     Next issue we will continue to introduce construction process of external insulation rock wool board.
