Product Description
The rock wool wall sandwich panel with an insulating rock wool core is a sandwich panel with high fire resistance. Its interior is filled with natural rock wool fibers perpendicular to the panel surface, which increases its mechanical strength and fire resistance. For the two sides of the panel, polyurethane edge sealing can be selected to increase the strength of the panel's insertion port. Or full rock wool can be used, which has a longer fire resistance time. Colored coated metal plates (PPGI/PPAI/PPAL) are used on both sides, and a variety of colors and thicknesses are available for selection. The integrated hidden screw installation will not cause damage to the panel due to screw corrosion, making the facade more beautiful.
The rock wool wall sandwich panel can withstand fire for up to 180 minutes in the thickest case. Therefore, we are facing a sandwich panel with the best fire resistance performance. This quality is highly demanded by professionals and individuals to protect their homes, premises, and businesses. We know that every customer is unique. Therefore, we not only provide you with fireproof rock wool sandwich panels of standard thickness, but you can also choose from various rock wool core thicknesses ranging from 50 mm to even 150 mm to meet more demanding construction requirements.
At the same time, we provide complete drawing technical support, installation guidance, and provide auxiliary materials required for sandwich panel installation.
Product Advantage
Excellent thermal insulation performance: The fiber structure of rock wool endows it with good thermal insulation properties. It can effectively reduce the energy consumption of buildings and maintain stable indoor temperature. In cold winters, it can block the cold outdoor air and reduce the use of heating. In hot summers, it can also block the incoming heat from outside and lower the load on air conditioners.
Outstanding fire resistance: Rock wool is a non-combustible material with a fire rating up to Class A. In the event of a fire, the rock wool exterior wall sandwich panel can effectively prevent the spread of fire. It can withstand fire for up to 180 minutes, winning precious time for personnel evacuation and fire rescue and ensuring the safety of buildings and people.
Good sound absorption and noise reduction performance: The porous structure of rock wool can absorb and reduce noise, providing a quiet and comfortable environment for buildings. It is especially suitable for buildings near noise sources such as traffic arteries and factories.
High strength and stability: The metal panel of the sandwich panel has high strength and stiffness. Combined with the rock wool core material, the overall structure is stable and can withstand certain wind loads, snow loads and seismic actions.
Waterproof and moisture-proof performance: The specially treated metal panel and sealing strip make the rock wool exterior wall sandwich panel have good waterproof and moisture-proof properties, avoiding the decline in thermal insulation performance and structural damage caused by moisture intrusion.
Beautiful and durable: The surface of the rock wool exterior wall sandwich panel can be processed with various colors and textures to meet the needs of different architectural styles. At the same time, with a hidden nail structure, it is corrosion-resistant and has a long service life.
