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
     2. Spray interface agent on the surface of rock wool board
     Choose rock wool board for external wall insulation, prepare a special interface agent, and spray both sides of the rock wool board to enhance the adhesion between the rock wool board and the polymer mortar.
     3. Hanging vertical line, pop-up window control line
     According to the requirements of the building facade, pop up the horizontal and vertical control lines of windows on the outer wall. Hang a vertical reference steel wire on the corner of the building's outer wall, and use theodolite to re-measure the verticality and flatness of the steel wire.
     4. Prepare bonding mortar
     Mix water and dry mortar powder according to the required ratio.
     5. Bonding alkali-resistant glass fiber mesh cloth
     The rock wool board on the side of the wall and the opening of the hole should be pre-applied with a narrow strip of mesh cloth.
