Advantages of Wall Sandwich Panel
Lightweight
Wall sandwich panel are lightweight, which makes them easy to handle, transport, and install. They can be used to construct buildings, walls, roofs, and floors, and they reduce the overall weight of the structure, which can save on material costs .
Wall sandwich panel are often made of fire-resistant materials, which makes them suitable for use inbuildings that require high levels of fire safety. They have low flammability and are designed to slow down the spread of fire.
Acoustic insulation
Wall sandwich panel are effective at reducing noise and can be used to create soundproof rooms or buildings. They absorb sound waves, preventing them from bouncing around and creating echoes.
Durability
Wall sandwich panel are durable and can withstand harsh weather conditions, such as wind, rain, and hail.They are also resistant to corrosion and do not require much maintenance.
Types of Wall Sandwich Panel
Glass Wool Sandwich Panel For Wall
To further improve the panel's performance, such as metal skins' tear strength, no cold bridge and no dewing, 50mm polyurethane edge sealing is added to both sides in the production process.
Insulated Metal PIR PU Foam Sandwich Panel
Insulated metal PIR PU foam sandwich panel is widely used in wall enclosure systems. PIR, with the full name Polyisocyanurate, has excellent thermal insulation performance. It is superior to PUR in terms of fire resistance, stability, mechanical strength, and production efficiency.
Fire Resistance Rock Wool Mineral Wool Sandwich Panel
It features a non-combustible, high-density rock wool core paired with high-quality color-coated steel sheets, offering Class A fire resistance, excellent thermal insulation, and outstanding soundproofing. Easy to install and cost-effective, it provides a finish comparable to aluminum curtain walls at a fraction of the cost.
Fire Rated Rock Wool Sandwich Panel Mineral Wool With PIR Side Sealing
Duowei Fire rated rock wool sandwich panel rock wool with PIR side sealing uses a unique togue and groove design to prevent the panel from falling off to the greatest extent. The rock wool core material with PIR side sealing not only ensures excellent fire resistance, but also has the function of anti-cold bridge.

Various Applications of Wall Sandwich Panel
Cold Storage Facilities
Application: Sandwich panels are a popular choice in building cold storages and refrigerated warehouses due to their excellent thermal insulation properties.
Benefit: They help maintain consistent low temperatures essential for food preservation, pharmaceuticals, and other perishable items, while also reducing energy consumption.
Commercial and Industrial Buildings
Application: Many commercial and industrial buildings utilize sandwich panels for external and internal walls, roofs, and partitions.
Benefit: Their lightweight yet strong structure makes them suitable for large-scale facilities, contributing to faster construction and energy efficiency.
Prefabricated Structures
Application: Prefabricated homes, offices, and modular buildings often incorporate sandwich panels due to their ease of assembly.
Benefit: They allow for quick construction while maintaining high standards of thermal insulation and durability.
Clean Rooms and Controlled Environments
Application: In settings requiring controlled environments, such as laboratories, hospitals, and manufacturing units, sandwich panels are used due to their airtight nature.
Benefit: They help in maintaining clean and controlled atmospheres, which is critical in these environments.
Wall Sandwich Panel Insulation Materials
Polyurethane (PUR)
Polyurethane is the rigid foam formed by mixture of main components ‘polyol and isocyanate’ with catalyst materials under high pressure and special production conditions.
Ensuring superior thermal insulation by its closed cell structure, polyurethane has high dimensional stability, and does not absorb water. It does not create bacteria. Its mechanical performance is very high thanks to its high compressive strength.
Polyisocyanurate (PIR)
A new macromolecular structure called polyisocyanurate is formed when the main components of the polyurethane foam chemically react at different mixture quantities. Polyisocyanurate rigid foam is the version of polyurethane with higher, enhanced fire resistance performance due to the difference in its structure. In case of a fire, the formation of smoke is very low when compared to polyurethane.
Mineral Wool
Mineral wool is the general name given to the fibers obtained by melting the inorganic rocks and other inorganic oxides at a high temperature. With its fibrous and open cell structure, mineral wool is the perfect choice for your building with regards to sound insulation and fire resistance. When it comes to thermal insulation, it has a lower insulation value compared to PUR and PIR.
Mineral wool in sandwich panels is sliced in our fully automatic production facilities, and their fibers are used in a position perpendicular to the panel surface. Therefore, the resistance of the panel against pressure is increased and its mechanical value is improved.
You may prefer to use the mineral wool insulation material especially for buildings that require high sound insulation or those under fire risk or for any building, where flammable/explosive materials are stored.
Expanded Polystyrene (EPS)
Expanded polystyrene is a thermoplastic material, a derivative of petroleum. The raw material of polystyrene, which has a micro-granular structure, is firstly heated and expanded with water vapor. Pentane gas, an organic component, is used to inflate the granules. After inflation process, the polystyrene granules stick firmly to one another and take the shape of the mold they are in. Finally, after having been shaped into blocks, expanded polystyrene is ready to use by cutting into sheets.
