Solid thermal insulation performance at a cost-optimized price point — a practical choice for refrigerated transport and modular building projects.
Product Overview
SKD FRP Sandwich Panels with XPS Core combine a weather-resistant FRP gelcoat outer skin, an extruded polystyrene (XPS) foam core, and an FRP inner skin — a structure engineered to deliver solid insulation performance while keeping cost efficiency front of mind.
XPS Core offers a practical alternative for buyers balancing insulation performance with budget, making it a common choice for refrigerated transport and modular building projects where cost efficiency matters alongside thermal performance.

Note on width and shipping：
Panel width is determined by standard container dimensions for shipping purposes. Panels wider than standard container dimensions cannot be transported and are therefore not available. Contact our team to confirm the maximum width for your specific container type and shipping route.
Why XPS Core
XPS Core delivers solid thermal insulation performance while offering a more cost-optimized price point compared to higher-performance core options. This makes it a practical choice for projects that need reliable insulation without maximizing every degree of thermal efficiency — such as modular buildings and cost-sensitive refrigerated transport projects.
Beyond insulation, XPS Core panels retain all the advantages of SKD’s FRP gelcoat technology: excellent weather resistance, moisture resistance, and long-term durability, backed by the same 10–15 year warranty as our standard gelcoat panels.
Applications
The XPS Core Sandwich Panel is suited for cost-efficient, insulated applications, including: Refrigerated Truck Bodies, Refrigerated Trailers, Refrigerated Containers, Modular Building Walls & Roof Panels, Temporary Structures, Cold Storage Walls & Panels, Cleanrooms (cost-sensitive projects), Agricultural Insulation Facilities, and Marine & Vessel Insulation.
A: XPS Core offers solid insulation performance at a more cost-optimized price point, making it a practical alternative for buyers balancing performance with budget. PU Core offers the best thermal insulation performance among our core options, for projects where insulation efficiency is the top priority. Contact our team to discuss which fits your project’s performance and budget needs.
A: Yes. Panel thickness is made to order based on your project’s insulation and structural requirements. Contact our team to discuss the right thickness for your application.
A: Our XPS core uses a closed-cell structure, which provides low water absorption, stable insulation performance, and better resistance to moisture compared with open-cell materials. This makes it suitable for applications where long-term insulation reliability is required.
A: Yes. XPS Core Sandwich Panels can be processed according to project requirements, including cutting, drilling, and assembly. We recommend following suitable processing methods to maintain the panel’s structural integrity and performance.
A: XPS Core Sandwich Panels combined with FRP gelcoat skins provide resistance against moisture, weathering, and environmental exposure, making them suitable for demanding indoor and outdoor applications.
