XPS sandwich panels are a type of composite panel consisting of an extruded polystyrene (XPS) foam core sandwiched between two layers of facing materials. These panels are known for their excellent thermal insulation, lightweight properties, high compressive strength, moisture resistance, and durability.
- Thermal Insulation
XPS foam cores offer excellent heat resistance, making them ideal for energy efficiency applications. - Lightweight
XPS foam has a low density and is lightweight, making XPS foam sandwich panels easy to handle, transport, and install. - High Compressive Strength
XPS foam has strong compressive resistance, making the panels suitable for load-bearing applications. - Waterproofing
XPS foam has a closed-cell structure that prevents water absorption, making the panels highly moisture-proof and waterproof. - Durability
XPS foam is not prone to rot or deformation, and has a long service life and stable performance.

Common XPS Sandwich Panels
How to Improve the Performance of XPS Sandwich Panels
In addition to the selection of high-quality materials and advanced composite technology, the scientific design of TOPOLOGROUP has greatly improved the performance of XPS foam sandwich panels.
- Pre-embed structural materials in XPS foam as a “skeleton” to enhance its structural strength. These materials include glass fiber profiles, waterproof wood, aluminum tubes, sheet metal, etc.
- Add energy-absorbing materials between the foam and the surface to enhance its impact resistance.
- XPS foam can be combined with other materials such as PET foam, PVC foam, plywood, etc. as a core material to improve the performance of sandwich panels.
Advanced Processing Technology
- Laser positioning ensures the accuracy of sandwich panels.
- Automatic glue spraying ensures uniform distribution of adhesive.
- Vacuum high-pressure composite ensures the bonding strength of sandwich panels.
- CNC machining completes the processing of complex shapes.
