外墻保溫層如果安裝不當，遇到溫差變化或受外界日曬、雨林的影響其飾面層就會出現開裂，不僅影響外觀，巖棉板保溫效果也大打折扣。因此在施工時要做好基層處理工作，基層平整潔凈才能保證保溫層附著良好。而鋪好的保溫層要經過驗收后才能開始抹面施工，應該選擇有防開裂效果的材料來施工，并且要粘貼一層網紗，這樣才能保證整個保溫系統的可靠和穩定。

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.

巖棉板雖說對于我們普通家庭來說還有點陌生，但在國外，特別是歐洲建筑市場中就存在大量巖棉板制品，據不完統計 ，北歐人均消耗量在20 kg以上，前蘇聯人均消耗量也在5 kg以上美國人均消耗量為5～10 kg。由于防火問題，在美國巖棉、礦渣棉的使用量就高達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%.

而在國內，巖棉的使用普遍較低，由于它有良好的保溫、隔熱、隔聲及吸音性能，所以被主要應用于能源、石油化工、船舶工業和建筑輕板的絕熱、防火、隔音等方面。其實它也是可以運到普通民宅上的。

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.
