FRP facing XPS sandwich panels combine the advantages of flat FRP (fiberglass reinforced) and XPS (extruded polystyrene), and is a composite material with balanced performance.
It has the following characteristics:
- Lightweight and high strength.
- Thermal insulation.
- Waterproof and moisture-proof.
- Smooth and flat surface.
- Fireproof, non-flammable.
- Durable, long service life.
FRP Facing & XPS Foam
Before understanding this composite panel, let’s first understand what is FRP sheet and XPS foam.
- FRP is the abbreviation of fiberglass reinforced plastic, which is a composite material of glass fiber and resin. The surface of TOPOLO FRP is treated with a unique gel coat, and the glass fiber type and arrangement are also diverse to meet different application requirements.
- XPS, the abbreviation of extruded polystyrene foam board, is a low-density thermal insulation material. TOPOLO XPS foam is a rigid closed-cell material with excellent compression resistance and waterproof properties.
Schematic Diagram of FRP Facing XPS Foam Sandwich Panels
The top and bottom layers of the composite board are gel-coated FRP sheets, and the middle layer is XPS (extruded polystyrene) foam board, which are composited into a panel using adhesive in a vacuum environment.

Applications of FRP Facing XPS Foam Sandwich Panels
FRP facing XPS composite panels are widely used in vehicles, buildings, public transportation, ocean and other fields. Such as RVs, refrigerated trucks, mobile homes, yachts, etc. It can be used as wall panels, floors, roof panels, partitions, door panels, etc.
TOPOLO – Expert in FRP Sandwich Panels
TOPOLO FRP facing XPS sandwich panels adopt a one-piece composite process and are highly automated in production. The product quality ranks among the best in China. We are the partner of many international companies in customizing high-end boxes or panels.
Optimization and Processing
Weathering Treatment
- Add flame retardants and anti-aging agents to increase the safety and service life of the composite panel.
Embedded Reinforced Structural Materials
- For some XPS sandwich panels that need to increase strength, reinforced structural materials such as timber, aluminum tubes, FRP tubes, high-strength plastic bars, etc. will be embedded inside.
CNC Machining
- Cutting, drilling and grinding of composite panels according to drawings.
Feature of FRP Facing XPS Sandwich Panels in TOPOLO
Flat and Smooth
- The surface of the FRP is flat and smooth, without dirty spots, and there are no obvious marks on the surface of the seams of the foam boards.
No Delamination
- FRP and XPS foams are closely bonded and extremely difficult to delaminate.
Stable Performance
- The FRP surface has been treated with UV protection to keep its original color for a long time outdoors. It can withstand high temperatures up to 80℃ without deformation and low temperatures as low as -40℃ without becoming brittle.
