XPS Core GRP Sandwich Panels

High-Performance FRP/XPS Composite Sandwich Panels

Fiber-Reinforced Plastic (FRP) sheets are advanced composites engineered from a resin matrix and embedded fiberglass reinforcement. This combination results in a material that is exceptionally strong, rigid, and lightweight, while also offering superior resistance to corrosion, moisture, and electrical conductivity.

When utilized as the outer skins in a sandwich panel with an Extruded Polystyrene (XPS) foam core, the resulting composite becomes the industry-standard material for the construction of high-quality campers, recreational vehicles (RVs), and box trucks. FRP/XPS panels provide a clearly superior alternative to traditional metal or wood-skinned panels, offering a comprehensive range of performance benefits.

Key Advantages:

• ☑ Lightweight: Significantly lower density than metal alternatives, improving fuel efficiency and payload capacity.

• ☑ High Strength-to-Weight Ratio: FRP possesses a far greater structural strength than plywood.

• ☑ Moisture and Rot Proof: Impervious to water, FRP will not rot or degrade like wood in wet conditions, nor will it corrode like steel.

• ☑ Thermal Insulation: The closed-cell structure of the XPS core provides excellent insulating properties, creating a more energy-efficient and comfortable interior environment.
