Extruded Polystyrene (XPS) Insulation Board for wall prefab house moudlar

Extruded Polystyrene (XPS) insulation board is a high-performance, closed-cell rigid foam board made from polystyrene resin through a continuous extrusion process. Known for its excellent thermal insulation properties, moisture resistance, and compressive strength, XPS is widely used in modern construction and building envelope systems.

Key Features and Advantages：

🔒 Closed-cell Structure
XPS has a uniform, closed-cell structure that makes it nearly impermeable to water and vapor, ensuring long-term insulation performance.

❄️ Superior Thermal Insulation
With a low thermal conductivity (typically around 0.030–0.034 W/m·K), XPS helps reduce energy consumption by minimizing heat transfer.

💪 High Compressive Strength
Designed to withstand heavy loads, XPS is suitable for use in load-bearing applications such as floor slabs, green roofs, and below-grade installations.

🌧️ Waterproof and Moisture Resistant
Unlike other insulation materials, XPS does not absorb water, making it ideal for humid, damp, or below-grade environments.

🧱 Long-Term Durability
XPS resists aging, corrosion, mold, and deterioration, maintaining performance for decades with minimal maintenance.
