Advantages of Wall Sandwich Panels
Outstanding thermal insulation
One of the most significant attributes of sandwich panels is their exceptional thermal insulation. The insulating core material effectively reduces heat transfer, helping maintain stable interior temperatures.
Enhanced fire safety
Many sandwich panels are designed with fire safety in mind. Materials like rockwool and pir offer increased fire resistance, slowing the spread of flames and providing additional time for evacuation and firefighting efforts.
Excellent acoustic properties
Sandwich panels also excel in sound insulation. The density and composition of the core material can significantly reduce noise transmission, making these panels ideal for environments where soundproofing is essential, such as recording studios, industrial facilities, and office buildings.
Structural strength and durability
Despite their lightweight nature, sandwich panels provide considerable structural strength. This strength is attributed to the composite action between the outer skins and the core, allowing the panels to withstand various loads and impacts.
Aesthetic flexibility
The versatility of sandwich panels extends to their aesthetic appeal. With a variety of finishes and colors available, they can be tailored to meet specific design requirements, enhancing the visual appeal of buildings.
Eco-friendly and sustainable
Sandwich panels support sustainable construction practices. Their energy efficiency and durability contribute to reduced environmental impact over the building’s lifecycle.

Fireproof performance: Rock wool core material is a non combustible material with a fusion temperature of over 1000 ℃, which can effectively block flames and minimize fire losses in a fire.
Thermal insulation and energy saving: Rock wool has a low thermal conductivity (0.043w/m · k) and good insulation performance. Excellent node design ensures sealing performance and insulation effect.
Good sound insulation: The sound insulation volume is ≥ 30DB, effectively reducing the interference of external noise.
Water tightness/air tightness: Polyurethane edge sealing is used, and a smooth tongue can effectively prevent water from entering; The connection between the building parts of the board is sealed internally to maintain good airtightness.
Durable and sturdy: Made of high-quality rock wool or glass wool, with high hydrophobicity and long-lasting stability.
Facade aesthetics: Hidden screw node design, high flatness of the board surface, rich color of the paint coating, and long-lasting color.

Application of Wall Sandwich Panels
Cold storage facilities
Sandwich panels are a popular choice in building cold storages and refrigerated warehouses due to their excellent thermal insulation properties.
Commercial and industrial buildings
Many commercial and industrial buildings utilize sandwich panels for external and internal walls, roofs, and partitions.
Prefabricated structures
Prefabricated homes, offices, and modular buildings often incorporate sandwich panels due to their ease of assembly.
Clean rooms and controlled environments
In settings requiring controlled environments, such as laboratories, hospitals, and manufacturing units, sandwich panels are used due to their airtight nature.
Installation Requirements of Wall Sandwich Panels
After the wall frame is installed, place the first sandwich wall panel on the predetermined position on the steel frame. Fastened with bolts to ensure a strong connection between the wall panels and the steel frame. It ensures the stability and structural integrity of the sandwich wall panels.
Continue to install other sandwich panels, these panels are designed to interlock or overlap and can be tightly connected together to ensure a seamless appearance. While maintaining the thermal, acoustic and structural properties of the walls. To ensure proper weather protection, use a method of sealing the corners and edges.
