Product Details
Insulated aluminum panels are widely used in construction, cold storage, and industrial buildings due to their thermal insulation, lightweight, and corrosion resistance. These panels consist of aluminum sheets bonded to insulation material such as polyurethane, polystyrene, or mineral wool.
Common Aluminum Alloy Grades for Insulated Panels
| Series | Typical Grades | Key Features |
|---|---|---|
| 1000 Series | 1050, 1100 | Excellent corrosion resistance, high ductility, good for forming and coating |
| 3000 Series | 3003, 3105 | Good corrosion resistance, medium strength, often used for architectural panels |
| 5000 Series | 5052 | Excellent corrosion resistance, marine and humid environments, moderate strength |
Why These Grades Are Chosen
Corrosion Resistance: Prevents panel degradation in outdoor or humid environments
Formability: Easy to roll, bend, and shape during manufacturing
Surface Finish: Smooth surface suitable for painting, coating, or anodizing
Differences Between Insulated Panels and Regular Aluminum Sheets
| Feature | Insulated Aluminum Panels | Regular Aluminum Sheet |
|---|---|---|
| Structure | Composite with insulation core (PU, PS, mineral wool) | Solid aluminum sheet |
| Thermal Performance | Provides thermal insulation (R-value) | No insulation |
| Weight | Lightweight due to core | Heavier per thickness |
| Strength | Structural rigidity enhanced by core | Depends only on aluminum thickness |
| Application | Walls, roofs, cold storage, clean rooms | General construction, machinery, decorative panels |
| Cost | Higher due to composite structure | Lower, standard aluminum material |
Typical Applications of Insulated Aluminum Panels
Cold storage rooms and freezers
Prefabricated buildings and warehouses
Clean rooms and laboratories
Roof and wall cladding for industrial or commercial buildings
