First, the advantages of external wall rock wool board
1. The external wall rock wool board is a kind of rock wool composite board used for building external walls, also called horizontal integrated board. This building material is convenient to install and construct and has good durability. It is a composite board with heat preservation and decoration functions. Among them, the use of rock wool interlayer can play a good role in fire prevention and heat preservation, and also has a good role in modeling and decoration in building decoration.
2. Rock wool composite board adopts CFC-free foaming technology, which has the characteristics of fiber or not. Low-temperature and high-temperature fire smoke does not produce toxic substances overflow, and phenolic foam waste can also be treated and reused, reducing environmental pollution and material waste. Rock wool composite board will have greater development and application in the future with its excellent product functions.
Nowadays, this material is widely used for decoration. For example, it will be used in schools, commercial buildings and villas. It is characterized by good heat insulation and good combustion performance, because rock wool belongs to inorganic mineral fibers and will not burn. Adding organic binders and many additives will affect some combustion functions.
4. The polymer-modified cement mortar and the continuous and uniform aluminum silicate board external wall system make the system have good toughness and water resistance, and solve the waterproof and airtight problems of aerated concrete and concrete hollow brick walls.
Second, the exterior wall rock wool board use points
1. If the finished rock wool board is vulnerable to mechanical wear under outdoor thermal insulation conditions, it should be wrapped with metal or plastic, and then pay attention to the joints and joint sealing, and seal with glue if necessary. The wrapping layer should be stacked locally not less than100 mm.
2. When the thermal insulation object is placed at 90 degrees and has a certain height, the thermal insulation layer of rock wool board must be provided with locating pins or support rings, and the spacing shall not be greater than 3m to prevent the thermal insulation data from slipping when there is vibration.
3. In order to achieve the purpose of minimum heat loss, the joints between rock wool board and felt must be closely butted. If there are multiple layers of insulation, cross joints need to be interwoven to avoid forming hot bridges, and cold bridges must be eliminated when keeping cold.
There are many plates in the decoration of the house, but there are many kinds of plates. So what are the advantages and precautions of the external wall rock wool board? Everyone who wants to see the introduction of the above small series knows.
