There are many types and specifications of rock wool composite boards, but the main difference lies in their bulk density, which mainly depends on the performance and mechanical strength of the insulation material. Consumers should choose different materials according to different usage conditions to achieve the desired effect.

High quality decorative materials are very important. Only green materials with good sound insulation can create a high-quality living environment. Installation is very simple because the product uses a fixed bolt drilling method, so no foundation treatment is required, and direct installation does not require keel hanging plates, thus shortening the construction period.

Rock wool composite board can indeed ensure our initial use effect, and it is not so troublesome during use. It can bring you more convenience, pay attention to the features correctly, and then use it better.

When choosing rock wool insulation materials, the first step is to select the insulation level of the material, that is, whether there are many environmental constraints. If there are many restrictions, the natural use effect will be affected.

The pore structure of rock wool composite board is stable and basically closed. It not only has good thermal insulation performance, but also has good frost resistance and sound absorption performance. Under normal use and maintenance conditions, the average service life of rock wool composite board structure can reach more than 30 years.
