Production process: the production process of rock wool board is three-dimensional interwoven with the internationally advanced pendulum method, while Glass wool cannot use this construction process, and can only be produced by plain weaving. Its strength illegally meets the requirements for climbing on the wall.

酸度系数：岩棉板的酸度系数≥1.6，玻璃棉的酸度系数≤1.6。而酸度系数越高对板的强度，耐高温，耐久性等性能有显著的提高。

Acid dissociation constant: Acid dissociation constant of rock wool board ≥ 1.6, Acid dissociation constant of Glass wool ≤ 1.6. The higher the Acid dissociation constant is, the better the strength, high temperature resistance and durability of the board will be.

强度要求：作为可以用于上墙的A级材料（棉制品），所要满足两方面强度的要求，1）是压缩强度需≥40Kpa，2）垂直于板面的拉伸强度需≥7.5Kpa。玻璃棉的这两个指标为0。

Strength requirements: As an A-grade material (cotton product) that can be used for wall mounting, it must meet two strength requirements: 1) the compressive strength must be ≥ 40Kpa, and 2) the tensile strength perpendicular to the board surface must be ≥ 7.5Kpa. These two indicators of Glass wool are 0.

尺寸稳定：岩棉板的尺寸稳定性相对比较稳定为≤1%，而玻璃棉的尺寸稳定性在≥8%。尺寸稳定性对保温系统有着至关重要的影响，尺寸稳定性差，容易使保温板膨胀或收缩，导致饰面层破坏，影响保温系统。

5. 施工方面：岩棉板所采用的是粘钉结合的方式，此方式大大保证的岩棉板的安全性，而玻璃棉由于其特性不能进行抹灰，故只能进行锚固形式固定，而玻璃棉没有压缩强度，所以板子本身相对较软，在锚固施工时很难施工。其安全性也相对降低。岩棉板施工容易，平整度能有效控制，玻璃棉无法保证其平整度。

Dimensional stability: the dimensional stability of rock wool board is relatively stable at ≤ 1%, while the dimensional stability of Glass wool is ≥ 8%. Dimensional stability has a crucial impact on the insulation system. Poor dimensional stability can easily cause expansion or contraction of the insulation board, leading to damage to the decorative layer and affecting the insulation system

5 Construction: The rock wool board adopts the method of bonding nails, which greatly ensures the safety of the rock wool board. Because Glass wool cannot be plastered, it can only be fixed by anchoring. Glass wool has no compressive strength, so the board itself is relatively soft, and it is difficult to construct during anchoring construction. Its safety is also relatively reduced. The construction of rock wool board is easy, the flatness can be effectively controlled, and Glass wool cannot guarantee its flatness.

工作温度：岩棉板的工作温度在≥650℃；玻璃棉的工作温度在≥250℃，虽然同为A1级防火材料，但两者在工作温度上的差别还是相当明显的。

Working temperature: The working temperature of rock wool board is ≥ 650 ℃; The working temperature of Glass wool is ≥ 250 ℃. Although both are A1 grade fireproof materials, the difference in working temperature between them is quite obvious.

耐火时间：岩棉板耐火时间为4h；玻璃棉的耐火时间为0.5h。

Fire resistance time: The fire resistance time of rock wool board is 4 hours; The fire resistance time of Glass wool is 0.5h.

导热系数：岩棉板的导热系数为≤0.040(W/m·k)（政府规定），目前实际导热系数能做到0.036（W/m·k）~0.037（W/m·k）。与玻璃棉的0.035（W/m·k）的导热系数基本差不多。

Thermal conductivity: The thermal conductivity of rock wool board is ≤ 0.040 (W/m · k) (government regulations), and currently the actual thermal conductivity can reach 0.036 (W/m · k) to 0.037 (W/m · k). The thermal conductivity is basically the same as 0.035 (W/m · k) of Glass wool

9. 干密度：相对于岩棉板140~160kg/m?的干密度，玻璃棉的10~16kg/m?就轻了很多，这是玻璃棉的一大优势。

9. Dry density: relative to rock wool board 140-160kg/m? Dry density of Glass wool, 10~16kg/m? It is much lighter, which is a major advantage of Glass wool.
