Aluminum Skin XPS Foam Sandwich Panels
Home » Materials » Foam Sandwich Panels » XPS Foam Sandwich Panels
- Lightweight
- Thermal Insulation
- Weather-resistant
- Flame Retardant
The sandwich panel features an extruded polystyrene (XPS) foam core sandwiched between two aluminum sheets. It combines the excellent thermal insulation and compressive strength of the XPS core with the lightweight and weather-resistant properties of aluminum. Using aluminum as the outer layer of a sandwich panel, instead of fiberglass reinforced plastic (FRP) sheets, steel sheets, or wood, can address many unique applications, particularly those requiring high standards of durability and structural strength.

Aluminum sheet grades and properties
Different grades of aluminum alloy sheets are used as the skin of sandwich panels. Some of them are softer and suitable for buffering and energy absorption, while others are harder and suitable for high-strength structural requirements.
| Series | Typical Alloy | Main Alloying Elements | Tensile Strength (MPa) | Corrosion Resistance | Workability | Heat-treatable |
|---|---|---|---|---|---|---|
| 1000 | 1060 | Pure aluminum | 95-125 | Excellent | Excellent | No |
| 3000 | 3003 | Manganese | 140-180 | Good | Good | No |
| 5000 | 5052 | Magnesium | 230-280 | Good | Good | No |
| 6000 | 6061 | Silicon, Magnesium | 240-290 | Good | Excellent | Yes |
| 7000 | 7075 | Zinc, Magnesium, Copper | 540-580 | Poor | Moderate | Yes |
Aluminum surface treatments
Because aluminum is easy to process, the surface of aluminum plates can be processed into a variety of rich textures and colors while maintaining long-lasting physical and chemical stability, and applied in different scenarios. For example, the smooth polished surface is suitable for wall panels, ceilings, partitions, etc., while the diamond-shaped plates are suitable for floors.
100% virgin XPS foam
XPS foam is a lightweight closed-cell foam with excellent thermal insulation, waterproofness, moisture resistance, and compression resistance. It is an ideal choice for manufacturing high-performance composite panels.
- The cells are densely packed, uniform, and of uniform size.
- The color is uniform and bright.
- The surface is smooth and resistant to breakage.
Applications
Aluminum skin XPS foam sandwich panels are suitable for facilities that require both thermal insulation and stable structure, such as:
Modular buildings
- Barracks, experimental rooms, equipment shelters, etc. that can be quickly installed and disassembled.
Insulated containers
- Cold storage and industrial equipment casings that maintain low internal temperatures, etc.
Vehicle bodies
- Reduce vehicle weight and enhance protection performance such as RVs, box trucks, fire trucks, tool trucks, etc.
