The thermal insulation rockwool board has excellent thermal insulation performance. And many houses need to install insulation materials during the construction process. Thermal insulation rockwool board is a good choice, but many people can not choose the right rock wool composite board.This issue we will introduce the method of choosing insulation rock wool board.

     1. Hygroscopicity: Hygroscopicity refers to the properties of materials that absorb moisture in the air. This property of thermal insulation rockwool board is related to the chemical composition and structure of the material. In addition to the chemical properties of the material surface, the properties of inorganic non-metallic materials are also related to the microstructure formed by the material.
     2. Appearance quality: the surface should be flat, and there should be no scratches or stains that affect actual use.
     3. Thermal load shrinkage temperature: The thermal load shrinkage temperature is used to characterize the moisture and thermal stability of the thermal insulation rock wool board. The wet rock wool composite board sample was immersed in the gradually heated water, and the thermal insulation rockwool board reached 643°C. When the thermal insulation rockwool board begins to shrink, the load shrinkage temperature of the thermal insulation rock wool board is 643 degrees, that is, when the external temperature reaches 643 degrees, the thermal insulation rockwool board will deform.
     4. Combustion performance: Combustion performance refers to all physical and chemical changes that occur when building materials burn or catch fire. This property is caused by the flammability of the material surface and flame spread, heat, smoke, charring, weight loss and toxicity. The production of a product is measured by characteristics. Thermal insulation rockwool board is noncombustible. Rock wool composite board is non-flammable.
     5. Organic content: Organic matter is mainly composed of oxygen, hydrogen and carbon. Organic matter is the material basis of life. Fat, amino acid, protein, sugar, heme, chlorophyll, enzyme, hormone, etc.
     Above is the introduction of choosing thermal insulation rockwool board. Hope this can bring you some help.
