1. Project Overview: The integrated insulation and decoration board is made of rock wool board for wall insulation.

2. Construction process flow: 1. Base interface treatment: The wall should be cleaned, oil stains should be removed, and floating dust should be cleaned. Loose and weathered parts of the wall should be removed clean. When the protrusion on the wall surface is greater than 10mm, it should be removed. In order to achieve uniform and homogeneous adhesion at the grassroots interface, the wall needs to be treated with interface mortar, which can be evenly coated with a spray gun or roller brush to ensure that all walls are treated with interface. Brick walls and aerated concrete walls should be moistened with water before interface treatment. When blocking pedestrian holes and abandoned holes, the debris, dust, and other objects inside the holes should be cleaned up, moistened with water, and then filled with 1:3 cement mortar to build them tightly.

3. Hanging vertical and bouncing control lines: The method of laying out is determined based on the height of the building. Using the corners of walls and both sides of doors and windows, use a theodolite to draw straight lines to find verticality, stretch low-carbon steel wires to find regularity, and control the intersection of horizontal lines based on the 500mm line above the floor elevation as the horizontal reference line. According to the vertical adjustment line and insulation thickness, snap control lines on both sides of the large angle at each step, and then pull horizontal lines as marker blocks.

4. Install insulation and decoration integrated slate cotton board: (frame bonding method+expansion bolt anchoring)

6. Good fire and flame retardant safety, users can rest assured that the insulation system of the integrated insulation and decoration board material will not burn in the first stage. Widely used in intensive residential areas, public buildings, large public places, flammable and explosive places, as well as places with strict fire prevention requirements. It can also be used as a fire isolation zone to improve building fire safety standards.

7. Good insulation performance: The insulation performance of the integrated insulation and decoration board is much better than that of organic insulation materials, and can be used for summer insulation in southern regions. At the same time, its thermal conductivity can be less than 0.050W/(mk), which can be adjusted according to the needs of mechanical strength and actual functional use, and can be used for ceilings in different occasions such as floors.

8. Good anti mold effect: It can prevent the conduction of cold and hot bridges, and prevent mold spots after condensation.

9. Good economy: The construction is simple and fast, the construction process is superior to ordinary plastering mortar, the construction cost is about 10 yuan/square meter, the construction period is shortened by more than half, and the service life is the same as that of a wall.
