2025-09-28
Purchase suggestion:
Choose rock wool products produced by legitimate manufacturers to ensure compliance with national standards (such as GB/T 25975-2018).
Select rock wool with different densities and thicknesses according to specific applications. For example, low-density rock wool (60-80kg/m ³) is suitable for sound absorption and noise reduction, while medium to high-density rock wool (100-150kg/m ³) is suitable for thermal insulation.
Check the fire rating, thermal conductivity, compressive strength and other performance indicators of rock wool to ensure that the product meets the requirements for use.
Usage suggestions:
In the construction of wall insulation, it is necessary to carry out base treatment, clean the wall surface, and ensure that it is flat, dry, and free of debris.
During the installation process of rock wool products, attention should be paid to docking and mutual squeezing of staggered joints to avoid the occurrence of seams.
When constructing the exterior wall decorative layer, it is necessary to ensure that the plaster layer reaches the design strength and the grid strip joint treatment before proceeding with the coating construction.
