Requirements of thermal insulation rock wool board

1. Thermal insulation performance

The thermal insulation performance of rock wool board directly affects the energy efficiency of buildings. When designing the curtain wall, it is necessary to ensure that the thermal conductivity (λ value) of the rock wool board used is as low as possible, and the rock wool board with λ value below 0.035 W/m·K is usually the best choice. At the same time, it is necessary to ensure that the thermal insulation performance of the material will not be affected by the external environment, such as humidity and temperature fluctuation.

2. Fire resistance

Curtain wall thermal insulation rock wool board should have excellent fire resistance. According to the relevant building fire protection code, the rock wool board should meet the requirements of incombustible materials, and will not release harmful gases in case of fire. Specifically, the fire protection rating of rock wool board should reach A1 level, which can resist the invasion of flame for a long time to ensure the safety of buildings.

3. Mechanical properties

In the construction process, the rock wool board needs to bear certain pressure and wind load. Therefore, rock wool board is required to have good compressive strength and tensile strength. At the same time, in order to ensure its stability during construction, the rock wool board should also have certain impact resistance during transportation and installation.

4. Sound absorption performance

In urban environment, noise pollution is becoming more and more serious, and the sound absorption performance of curtain wall thermal insulation rock wool board has become an important consideration. Choosing rock wool board with excellent sound absorption performance can effectively reduce the noise inside and outside the building and help improve the comfort of living and working environment.

5. Construction performance

The construction performance of rock wool board can not be ignored either. Rock wool boards that are easy to cut and shape and can be firmly attached to other building materials should be selected. This can reduce the construction difficulties, improve the construction efficiency and ensure the construction quality.
