Introduction to XPS Extruded Polystyrene Insulation
XPS (Extruded Polystyrene) Board is a high-performance rigid foam insulation material engineered for superior thermal efficiency, moisture resistance, and structural durability. Manufactured through an advanced extrusion process, XPS insulation boards feature a closed-cell structure that delivers exceptional insulation properties, making them ideal for a wide range of construction and industrial applications.
Unlike traditional EPS (Expanded Polystyrene), XPS foam boards offer higher compressive strength, lower water absorption, and improved long-term thermal performance. These characteristics make XPS extruded polystyrene the preferred choice for architects, builders, and engineers seeking reliable insulation solutions for roofs, walls, floors, and below-grade applications.
Key Advantages of XPS Insulation Boards
1. Outstanding Thermal Insulation Performance
Low Thermal Conductivity (λ-value: 0.028 – 0.034 W/m·K) – Ensures maximum heat retention, reducing energy consumption in buildings.
High R-Value per Inch – Provides better insulation efficiency compared to other foam boards, lowering HVAC costs.
2. Superior Moisture & Water Resistance
Closed-Cell Structure – Prevents water absorption (<1% by volume), making it ideal for damp environments, basements, and exterior applications.
Mold & Rot Resistance – Unlike fiberglass or mineral wool, XPS boards do not degrade when exposed to moisture.
3. Exceptional Compressive Strength (150 – 700 kPa)
Supports heavy loads, making it suitable for roofing systems, under-slab insulation, and industrial flooring.
Maintains structural integrity even under constant pressure, preventing insulation breakdown over time.
4. Lightweight & Easy to Install
Reduces labor costs and installation time compared to bulky traditional insulation materials.
Can be easily cut and shaped for customized applications.
5. Long-Term Durability & Sustainability
Resistant to Freeze-Thaw Cycles – Performs reliably in extreme temperatures (-50°C to +75°C).
Eco-Friendly Options Available – Some XPS insulation products use recycled materials and are 100% recyclable.
6. Fire Safety Compliance
Available in Class B (Standard) and Class A (Fire-Retardant) grades to meet building safety regulations.

✔ Floor & Under-Slab Insulation
Prevents heat loss in radiant floor heating systems and cold storage facilities.
Used in basement insulation to block ground moisture.
✔ Foundation & Below-Grade Insulation
Protects against soil moisture and frost heave in foundation walls and crawl spaces.
✔ Refrigerated Warehouses & Cold Chain Logistics
Maintains stable temperatures in food storage, pharmaceutical warehouses, and industrial freezers.
✔ Passive House & Green Building Projects
