外墙保温层如果安装不当，遇到温差变化或受外界日晒、雨林的影响其饰面层就会出现开裂，不仅影响外观，岩棉板保温效果也大打折扣。因此在施工时要做好基层处理工作，基层平整洁净才能保证保温层附着良好。而铺好的保温层要经过验收后才能开始抹面施工，应该选择有防开裂效果的材料来施工，并且要粘贴一层网纱，这样才能保证整个保温系统的可靠和稳定。

If the external wall insulation layer is installed improperly, it will crack in the decorative layer when encountering changes in temperature difference or being affected by external sunlight or rainforest, which not only affects the appearance but also greatly reduces the insulation effect of rock wool board. Therefore, during construction, the first step is to do a good job in grassroots treatment. Only when the grassroots is flat and clean can the insulation layer adhere well. The insulation layer that has been laid must undergo acceptance before the plastering construction can begin. Materials with anti cracking effects should be selected for construction, and a layer of mesh should be pasted to ensure the reliability and stability of the entire insulation system.

岩棉板虽说对于我们普通家庭来说还有点陌生，但在国外，特别是欧洲建筑市场中就存在大量岩棉板制品，据不完统计 ，北欧人均消耗量在20 kg以上，前苏联人均消耗量也在5 kg以上美国人均消耗量为5～10 kg。由于防火问题，在美国岩棉、矿渣棉的使用量就高达70%。

Although rock wool board is a bit unfamiliar to our ordinary families, there are a large number of rock wool board products in foreign countries, especially in the European construction market. According to incomplete statistics, the per capita consumption in Nordic countries is over 20 kg, and the per capita consumption in the former Soviet Union is also over 5 kg. The per capita consumption in the United States is 5-10 kg. Due to fire prevention issues, the usage of rock wool and slag wool in the United States is as high as 70%.

而在国内，岩棉的使用普遍较低，由于它有良好的保温、隔热、隔声及吸音性能，所以被主要应用于能源、石油化工、船舶工业和建筑轻板的绝热、防火、隔音等方面。其实它也是可以运到普通民宅上的。

In China, the use of rock wool is generally low. Because of its good thermal insulation, heat insulation, sound insulation and sound absorption performance, rock wool is mainly used in energy, petrochemical industry, shipbuilding industry and thermal insulation, fire prevention and sound insulation of light building boards. In fact, it can also be transported to ordinary residential buildings.
