Color steel rock wool sandwich panel

Although rock wool sandwich panels contain the word "cotton," they are vastly different from the everyday "cotton" or "sponge" we commonly encounter. Rock wool emphasizes the "rock" aspect—indeed, this rock is basalt, which is typically black. Its main component is the same as sand: silicon dioxide. Through artificial processing, a non-combustible inorganic fiber is extracted, which is what we refer to as rock wool. The new type of rock wool insulation panel, made using basalt as the raw material, has greater development potential compared to traditional rock wool products.

Rock wool sandwich panels serve different functions depending on the field and location of use. When used for external wall insulation, they are commonly known as external wall rock wool sandwich panels. Broadly speaking, these panels are primarily used for wall insulation, roof insulation, door insulation, and floor insulation, with the main application being wall insulation. Wall insulation can be implemented in two forms: on-site sandwich walls and factory-precast sandwich walls. The former uses rock wool sandwich panels along with air as an interlayer, while the latter involves directly attaching the rock wool sandwich panel to the building's exterior and then adding a decorative layer on its surface.

The installation of external wall rock wool sandwich panels is convenient, requiring only laying on the external wall. During use, maintaining the ambient temperature below 300 degrees Celsius ensures effective insulation. Generally, the likelihood of damage to rock wool sandwich panels is relatively low, and once installed, they can last for at least ten years.

External wall rock wool sandwich panels are relatively lightweight compared to other insulation materials, reducing many unnecessary hassles during transportation and lowering transportation costs. Previously, many materials were used for external wall insulation, but each had its own drawbacks. External wall rock wool sandwich panels have market prospects due to their comprehensive performance, and they are currently widely used and have broad coverage in the market.

The excellent insulation performance of external wall rock wool sandwich panels has made them popular among many consumers. Today, the market for this product remains highly active, largely because its characteristics align with current environmental protection requirements.

Color Steel Sandwich Panel Structure:

Inner/outer panel surfaces: Made of aluminized, galvanized, or aluminized-zinc color steel plates, with a thickness of 0.3-1.2mm, customized according to customer requirements.

Rock wool density: 60-120kg per square meter, oriented perpendicular to the color steel plate, with a flat contact surface and no obvious gaps. The rock wool is sandwiched inside, and the inner and outer surfaces, as well as the sides, are bonded with polyurethane foam adhesive.
