Product Details
Rock wool sandwich panel is a type of sandwich panel made from rock wool as raw material, which fully utilizes the unique properties of rock wool core material and has significant effects in fire prevention, thermal insulation, sound absorption and insulation.
Structure of rock wool sandwich panel
Rock wool sandwich panels mainly consists of the following three parts:
- Surface material: The surface of rock wool panels usually uses various metal sheets as panels, such as color coated steel plates (also known as color coated steel plates), galvanized steel plates, stainless steel plates, or aluminum plates. These surface materials not only have a beautiful appearance, but also have good corrosion resistance and wind pressure resistance, which can protect the rock wool core material from external environmental erosion.
- Core material: The core layer of rock wool sandwich panel is rock wool, which is an inorganic fiber material with excellent fire resistance, insulation, heat insulation and sound absorption properties. Rock wool core material is processed into boards with a certain thickness and density through specific processes, and filled between surface materials to provide insulation, heat preservation, and enhance structural strength.
- Adhesive layer: In the manufacturing process of rockwool sandwich panels, a special adhesive is usually used to firmly bond the surface material and core material together. This adhesive needs to have good bonding performance and weather resistance to ensure that the rock wool sandwich panel will not experience delamination or cracking during long-term use.

Characteristics of rock wool sandwich panel
- Excellent fire resistance: The raw material of rockwool sandwich panel is natural rock, which has excellent fire resistance. According to relevant tests, the fire resistance limit of rock wool sandwich panels can reach more than 4 hours, effectively preventing the spread of fires.
- Good insulation performance: Rock wool sandwich panels have low thermal conductivity, which can effectively reduce heat transfer and maintain stable indoor temperature.
- Significant sound absorption and insulation effect: Rock wool sandwich panels have good sound insulation effect, which can reduce the impact of noise on work and life.
- Good stiffness: Rock wool sandwich panels have high compressive, tensile, and bending strength, suitable for the structural requirements of various buildings.
- Reasonable fastening method: The polyurethane double-sided rock wool roof panel adopts a fastening interface to save the use of parts.
- The fixing method is firm and reasonable: The polyurethane double-sided rock wool roof panel is fixed with specially made M6 self tapping screws and steel purlins, which can resist strong external forces such as typhoons.

Application of rock wool sandwich panel
Rock wool sandwich panels are widely used in various fields due to their excellent performance:
- In the field of public buildings, rock wool panels are widely used in office buildings, hotels, hospitals and other public buildings. Their superior fire resistance and thermal insulation properties provide a safe and comfortable working environment for personnel.
- In the field of industrial construction, rock wool sandwich panels can be used for the exterior walls and roofs of industrial plants, warehouses, and other buildings, effectively reducing energy consumption and lowering operating costs.
- In the field of scientific research architecture, buildings such as research office buildings have high requirements for fire performance, and rock wool sandwich boards precisely meet this demand. In addition, its sound insulation and absorption performance also helps improve the work efficiency of researchers.
- In the field of environmental protection and energy conservation, rock wool sandwich panel is a green and environmentally friendly building material that does not contain harmful substances and does not pollute the environment. At the same time, its thermal insulation performance helps to reduce the energy consumption of buildings, which is in line with the policy orientation of energy conservation and emission reduction.
Advantages of rock wool sandwich panel
- Short installation cycle: The rock wool sandwich panel adopts prefabricated components, making on-site installation simple and fast, greatly shortening the project cycle and reducing construction costs.
- Scratch protection: During the production of rock wool sandwich board, polyethylene adhesive protective film can be pasted on the surface to avoid scratches or wear on the surface coating of the steel plate during transportation and installation.
- Beautiful and generous: The interface of the rock wool sandwich panel is designed according to European standards, with a smooth and smooth appearance, a flat and beautiful surface, tight joints, reliable strength, and effective prevention of cold and hot bridges.
