Insulated FRP composite panels engineered for thermal performance — five core options to match your application.
What Is FRP Sandwich Panel?
FRP Sandwich Panels combine a durable FRP gelcoat outer skin with an insulating core and an FRP inner skin, delivering a lightweight, structurally sound panel engineered for thermal insulation performance.
Five core options let you match insulation performance to your project's exact requirements, from maximum efficiency to cost-optimized solutions.
The sandwich structure delivers strength and rigidity at a fraction of the weight of solid materials, reducing transport and installation costs.
The FRP gelcoat outer skin resists moisture, corrosion, and UV degradation, protecting the insulating core over the panel's service life.
Panel thickness is made to order, and widths are sized to standard container dimensions to streamline shipping and logistics.
PU, XPS, PET, Honeycomb, and Plywood cores — each engineered for different performance, budget, and structural needs.
Backed by the same 10–15 year warranty as our FRP Gelcoat Panels, our sandwich panels are built for long-term performance with minimal maintenance.
