XPS Foam Sandwich Panel

XPS Foam Sandwich Panels combine an extruded polystyrene (XPS) foam core with rigid skin layers—typically fiberglass reinforced plastic (FRP), aluminum, or plywood—bonded through vacuum compression molding. The closed-cell XPS core delivers thermal insulation with conductivity between 0.024 and 0.034 watts per meter-kelvin, compressive strength from 0.1 to 1 megapascal, and density of 30 to 50 kilograms per cubic meter. Water absorption remains below 1 percent, while the material performs reliably from -50 to +80 degrees Celsius.

FRP skins provide high strength, rigidity, and corrosion resistance along with waterproof and electrical insulation properties. Aluminum skins offer lightweight, recyclable construction with optional fluorocarbon coatings for enhanced durability. Both skin types bond to the core using high-quality adhesives, ensuring uniform adhesion and structural integrity.

These panels serve construction applications including wall systems, roofing, and partitions where thermal insulation is required. Transportation industries use them for refrigerated truck bodies, recreational vehicles, and marine vessels. Cold storage facilities rely on them for temperature-stable walls and roofs, while industrial settings benefit from their customizable dimensions—widths to 3.2 meters, lengths to 12 meters, and thicknesses from 10 to 120 millimeters—with CNC (Computer Numerical Control) machining available for precise fabrication.
