Bulk density is one of the parameters of many performance indicators of rock wool board, and this parameter is very important. The size of the volume weight is directly related to the physical properties and thermal insulation effect of the rock wool board.

Bulk density, in short, refers to the mass per unit volume of a substance. For the rock wool board, the bulk weight refers to the weight of the rock wool material per unit volume.

The high bulk weight of the rockwool board means that more material is compressed into a unit volume, and the internal fiber content is usually higher, with relatively small gaps between the fibers. This helps to improve the structural strength and durability of the rockwool board. In some cases that need to withstand heavy pressure or long-term use, rock wool boards that meet the bulk weight standards can provide better support and protection.

In addition, the thermal insulation effect of different bulk weight rock wool board is not the same. Too large or too small rock wool board volume weight its thermal conductivity will be larger, therefore, select the appropriate rock wool board volume weight can achieve good thermal insulation effect, can effectively block heat conduction, improve the building's energy saving performance.

Bulk density is also an important index to measure the quality of rock wool board. Qualified rock wool board should have a stable volume weight, so as to ensure that it can maintain stable performance under various environmental conditions. If the volume weight is too low or too high, it may cause the rock wool board to perform poorly in thermal insulation, and may even cause other quality problems.

Therefore, in order to ensure that the rock wool board has good thermal insulation performance and quality stability, it is very necessary to develop a volume weight standard. This can not only regulate the production and sales of rock wool board, but also provide consumers with a clear reference index to help them choose rock wool board products that suit their needs.
