XPS extruded polystyrene board is a high-performance insulation material widely used in cold storage, building walls, roofing, and flooring systems. Manufactured through a continuous extrusion process, XPS boards feature a closed-cell structure, ensuring low thermal conductivity, excellent moisture resistance, and superior compressive strength. These properties make XPS insulation panels ideal for applications that require long-term thermal performance and durability.


Low Thermal Conductivity – Ensures excellent insulation performance, reducing energy loss.
Moisture Resistance – Closed-cell structure prevents water absorption and maintains thermal efficiency.
High Compressive Strength – Withstands heavy loads without deformation, suitable for flooring and roofing.
Lightweight and Easy to Install – Simple cutting and handling reduce labor costs.
Long Service Life – Resistant to decay, mold, and chemical corrosion.

XPS insulation boards are widely used for building insulation, cold room panels, underfloor heating systems, and roof insulation. Their excellent thermal performance and high compressive strength make them suitable for both residential and industrial projects.
Common thicknesses range from 20mm to 100mm, with 25mm, 50mm, and 75mm being popular choices. Custom thickness is available upon request.
Yes. Thanks to its closed-cell structure, XPS has extremely low water absorption, maintaining insulation performance even in humid or wet conditions.
Yes. XPS boards have high compressive strength, typically 200–700 kPa, making them suitable for applications under concrete floors, parking decks, and cold storage bases.
No. We support small orders and samples, but customers need to bear the sample shipping cost.
