Glass wool and rock wool are widely used in the construction industry, but there are still some customers who are not familiar with the difference between glass wool and rock wool. They often think that glass wool and rock wool are the same product, but in fact, glass wool and rock wool are different. So how can we distinguish them? Below, let's elaborate on 5 different points by the editor of Shengyuan.

一、原材料和生产工艺不同

1、 Different raw materials and production processes

玻璃棉原材料是玻璃为主，再按照适合的比例配加其它各种辅料混合后送入玻璃熔炉中充分融化再经多道工序，完成固化过程、产品定型、定型后经切割便成了预定产品，再进行包装。

The raw material of glass wool is mainly glass, which is then mixed with various other auxiliary materials in a suitable proportion and sent to a glass furnace for full melting. After multiple processes, the curing process, product shaping, and cutting are completed to form the predetermined product, which is then packaged.

岩棉是由玄武石为主要原料，经高温熔融，由离心设备制成无机纤维后再加入特质粘结剂和防尘油经摆动带铺毡并通过一些设备改变纤维排列结构，后经固化定型而制成的新型轻质保温材料。

Rock wool is a new type of lightweight insulation material made from basalt as the main raw material, which is melted at high temperature and made into inorganic fibers by centrifugal equipment. It is then added with special binders and dustproof oil, laid on a swing belt, and the fiber arrangement structure is changed through some equipment. Finally, it is solidified and shaped.

二、产品性能不同

2、 Different product performance

玻璃棉比岩棉容量低、渣球含量少、导热系数低、使用年限长、纤维韧性大。

Glass wool has lower capacity, less slag ball content, lower thermal conductivity, longer service life, and greater fiber toughness than rock wool.

二、产品用途不同

2、 Different product uses

玻璃棉一般用于低于200℃的保温部位，多用于一般建筑物货低温管道的保温，岩棉一般用于温度在500℃的保温部位，多用于高温热力管道和电力设备的保温。

Glass wool is generally used for insulation parts below 200 ℃, and is mostly used for insulation of general buildings and low-temperature pipelines. Rock wool is generally used for insulation parts at a temperature of 500 ℃, and is often used for insulation of high-temperature thermal pipelines and power equipment.

三、产品容量不同

3、 Different product capacities

玻璃棉容重为10kg/m3-64kg/m3，岩棉容重为40kg/m3-200kg/m3，因此岩棉的机械强度大于玻璃棉，所以岩棉成为了现代外墙壁挂保温防火的先选材料。

The unit weight of glass wool is 10kg/m3-64kg/m3, and the unit weight of rock wool is 40kg/m3-200kg/m3. Therefore, the mechanical strength of rock wool is greater than that of glass wool, making rock wool the first choice material for modern exterior wall insulation and fire prevention.

二、憎水性能不同

2、 Different hydrophobic properties

憎水性能也就是耐水渗透的一个性能指标。玻璃棉不会因为浸水和淋雨而破裂，被水浸泡后易行干燥，性能稳定。岩棉被水浸泡后即会软塌，性能丧失很多。

Hydrophobicity is also a performance indicator of water permeability resistance. Glass wool will not break due to immersion in water or rain, and it is easy to dry after being soaked in water, with stable performance. Rock wool will collapse and lose a lot of performance after being soaked in water.
