A sandwich panel is a building material made of three layers. It has two outer layers and a core in the middle. This design offers many benefits, making it popular in construction.
- About 28% of sandwich panels are used for building walls.
- Around 22% are used for roofs.
- Cold storage uses about 18% of these panels.
Sandwich panels are often used for walls because they insulate well, are easy to install, and are strong. They are light but tough, making them great for outside walls in homes, offices, and factories.
These panels are strong, insulate well, and are lightweight. For example, PUR Bs2 Sandwich Panels are known for keeping heat in and being light, taking up 10% of the market. EPS Sandwich Panels, used 14% of the time, are cheaper and also insulate well.
Key Takeaways

Composition of a Sandwich Panel
Outer Layers
Materials used (e.g., steel, aluminum)
The outer layers are made from strong materials like steel, aluminum, or fiberglass-reinforced plastic (FRP). Each has its own advantages. For example:
- Steel: Coated steel resists rust and handles tough weather well.
- Aluminum: It is light, doesn’t rust, and works in all climates.
- FRP: It is strong, light, and great for wet areas.
These materials keep the panel sturdy and dependable in many conditions.
Functions of the outer layers (e.g., protection, durability)
The outer layers protect the core and make the panel last longer. They block damage from impacts, sunlight, rain, and snow. This design helps the panel stay strong and in good shape.
Tip: Use stainless steel outer layers in food factories. They are easy to clean and hygienic.
Core Material
Common core materials (e.g., PIR, PUR, EPS, mineral wool)
The core is key to how the panel works. Common cores include:
- Polyurethane (PUR): Great for keeping heat in and saving energy.
- Polystyrene (EPS): A cheaper option for basic insulation needs.
- Mineral Wool: Resists fire and blocks noise, perfect for factories.
The core material depends on what the project needs.
Functions of the core (e.g., thermal and acoustic insulation)
The core keeps heat in and blocks noise. It helps save energy by keeping rooms warm or cool. For instance, polyurethane cores can lower energy use by 70%. Mineral wool cores also reduce sound, making spaces quieter.
Adhesive Layer
Role of adhesives in bonding layers
The adhesive layer sticks the outer layers to the core. It spreads stress evenly, making the panel stronger and more stable.
Types of adhesives used
Special adhesives like polyurethane or epoxy are used. These adhesives create a strong bond, even in tough conditions, helping the panel last longer.
Note: The adhesive layer is very important for keeping the panel strong over time.
Types of Sandwich Panels
