First, fix the glass wool to the wall with insulation supporting pins to prevent falling. A vapor barrier must be built on the surface of glass wool in order to prevent moisture condensation in the air within the glass wool, which may lead to the decrease of thermal insulation performance. (1) base treatment 1) the vertical control line of the entire surface must be correct, and the verticality of corners must be strictly controlled. 2) clean the floating dust, greasy dirt of release agents of concrete wall surface, masonry wall projections must be removed with a small shovel. 3) clean up the concrete blocks, slags in the joint part of shear walls, then repair again, according to the thickness of ash cake with the proportion of 1:3, and paster with cement mortar.
Construction method: First, fix the glass wool to the wall with insulation supporting pins to prevent falling. A vapor barrier must be built on the surface of glass wool in order to prevent moisture condensation in the air within the glass wool, which may lead to the decrease of thermal insulation performance.
Rock wool board should be pasted from the bottom up, in the horizontal direction it should be pasted from corners to windows to the sides; during pasting, it should be squeezed paste softly and evenly, internal and external corners should be rubbed and lapped; after finishing pasting, then check the flatness and perpendicularity with a 2 m ruler; rock wool board should be re-pasted if the tolerance is too large(the error is greater than 2 mm); when pasting around door and window openings, complete rock wool board should used, and the patchwork of rock wool board can not just be in the corners of window and door openings. Rock wool board pasted to corners should exceed the minimum size of 200 mm. I hope my answer help you.
