How to do rock wool board exterior wall insulation

2018-04-28 19:12:50

First tell you the characteristics of the rock wool board with A grade fire prevention, thermal insulation and other characteristics, is designed for the building external insulation thin plastering system, rock wool, slag wool at room temperature conditions (about 25 ° C) thermal conductivity is usually between 0.036 ~ 0.041W/(m·K), its own inorganic silicate fiber, non-combustible. External wall insulation should be building science, material science, fire science and environmental protection science organic combination of the four disciplines. Fire is something that no one wants to see, and in the external wall insulation system, you must not pay attention to one or the other. When using rock wool insulation board, it is necessary to ensure the insulation effect and pay attention to whether the fire performance meets the standard, in addition, it is also necessary to help save energy while preventing fire, not because of the fear of fire, but pay great attention to fire prevention, but ignore the important principle of energy saving. The inorganic thermal insulation material is represented by rock wool. It is suitable for external wall insulation or energy-saving transformation of existing buildings with dense structure such as concrete or brick walls, and can also be used as external wall insulation and fire isolation belt, which can be used with thermal insulation materials with combustion performance less than A level to improve the fire prevention function of external walls of buildings. Any research that deviates from the four disciplines has relative one-sidedness and limitations. The fire prevention of external wall insulation needs to do the following: 1. Choose good insulation materials; 2. Strictly implement various fire laws and regulations and fire control systems; 3. Monitor the construction process in the intermediate stage of the use of thermal insulation materials to prevent the possibility of various fires; 4. Take fire prevention measures in the primary stage of the use of thermal insulation materials; 5. After the insulation material is made into the external wall insulation system, the correct use of the insulation system and the prevention of fire.
