Characteristics of rock wool sandwich panels: Good fire performance: The raw materials, production process, and formula used in rock wool boards give them good fire performance. Tests show that it has fire resistance exceeding 1000°C.
Good thermal insulation. Significant sound absorption and insulation effect, sound insulation. Rock wool sandwich panels have a significant reduction effect on noise transmission, especially suitable for places where designated flights pass. In addition, after using rock wool roof panels, the indoor noise caused by the impact of rain and hail on the building roof steel plate is also significantly reduced.
Sound absorption: Rock wool sandwich panels also have excellent sound absorption effects, they can absorb sound in a wide frequency range.
Sealing performance: Polyurethane double-sided sealed rock wool sandwich panels adopt assembly line technology, utilizing the excellent waterproof property of polyurethane products, overcoming the disadvantage of rock wool being easy to absorb water and deliquesce, effectively extending product service life in terms of physical properties.
Aesthetic performance: The interface is designed according to relevant standards. The appearance is round and smooth, the surface is smooth and beautiful, the joints are tight, the strength is reliable, effectively preventing the generation of cold and hot bridges.
Good rigidity: Polyurethane double-sided sealed rock wool core material and two layers of steel plate are bonded to form a whole and work together. Coupled with the corrugated pressure profile on the top surface of the roof panel, the overall rigidity is much better than rock wool (glass fiber) on-site composite panels. After the sandwich panel is fixed on the purlin through connectors, the overall rigidity of the roof is greatly improved, and the overall working performance of the roof is strengthened. Using rock wool sandwich panels, larger purlin spacing can be adopted, saving 1/3 to 2/3 of purlin quantity.
Reasonable fastening method: Polyurethane rock wool roof panels on both sides adopt concealed buckle connection, avoiding hidden leakage at roof panel joints and saving the number of accessories.
Firm and reasonable fixing method: Polyurethane double-sided sealed rock wool roof panels use special M6 self-tapping screws and purlin fixing, which can effectively resist external forces such as typhoons. Self-tapping screws are set at the apex of the joint between two roof panels, adopting a special waterproof structure, avoiding weak links in waterproofing.
Short installation cycle: Since no secondary on-site processing is required, polyurethane double-sided sealed rock wool sandwich panels can not only keep the surrounding environment clean and not affect the normal operation of other processes, but also greatly shorten the installation cycle of single panels. The daily installation area of rock wool sandwich panels is 600-800㎡
Scratch protection: In the production of polyurethane double-sided sealed rock wool sandwich panels, polyethylene self-adhesive protective film can be pasted on the surface to avoid scratches or wear on the steel plate surface coating during transportation and installation.
Application of rock wool sandwich panels:
Widely used in roofs and walls of steel structure factories, simple mobile houses, ceilings and partitions of air clean rooms.
How to make soundproof panels?
A fireproof and soundproof rock wool insulation board, including upper rock wool board and lower rock wool board, also includes a middle fireproof and soundproof layer. The middle fireproof and soundproof layer is formed by splicing several soundproof boards, and the joints between adjacent two soundproof boards are filled with vitrified microbeads.
Rock wool boards can be used as roofs. General buildings using rock wool boards have excellent fireproof and thermal insulation properties. Therefore, it is widely used in various buildings. It is a cost-effective and excellent performance insulation material that can meet the design requirements of building roofs.
Does rock wool cause cancer?
Rock wool has been used for decades and has been widely applied, but many people suspect that the fibers it releases will be inhaled and used, with a risk of cancer. To this end, international cancer institutions have conducted corresponding investigations and research. Therefore, there is no evidence that rock wool increases the risk of lung cancer or mesothelioma. The following studies also show that the same is true for other cancers. Moreover, rock wool as an insulation material has a long history and its decomposition speed is also very slow, deepening people's misunderstanding. Many tests have been done and found that most are non-carcinogenic.
