High-Strength Thermal Insulation Extruded Board – Superior Energy-Efficient Construction Material
High-strength thermal insulation extruded boards (XPS boards) are premium construction materials designed to deliver exceptional thermal insulation, structural strength, and long-term durability. These boards are manufactured from high-density extruded polystyrene, ensuring low water absorption, high compressive strength, and resistance to deformation under heavy loads.
Ideal for residential, commercial, and industrial construction, high-strength XPS boards effectively reduce heat transfer, improve energy efficiency, and protect buildings from moisture and mold. Their lightweight yet strong construction makes them suitable for walls, roofs, floors, and industrial insulation applications.
High-strength thermal insulation extruded boards provide multiple performance benefits for modern construction:
Low thermal conductivity ensures reduced energy loss.
Improves heating and cooling efficiency, lowering operational costs.
Capable of withstanding heavy loads without deformation.
Suitable for roof insulation, flooring, and industrial platforms.
Minimal water absorption prevents mold growth and structural damage.
Ideal for basements, exterior walls, and wet environments.
Reduces labor costs and installation time.
Simplifies transportation and on-site handling.
Resistant to shrinking, warping, or cracking.
Maintains consistent performance over the lifespan of the building.

High-strength thermal insulation extruded boards are available in a variety of thicknesses, densities, and sizes to meet diverse project needs.

| Thickness | 20 mm – 120 mm | Customizable for walls, roofs, and floors |
| Density | 35–45 kg/m³ | High compressive strength for load-bearing applications |
| Thermal Conductivity | 0.029–0.035 W/m·K | Efficient energy-saving performance |
| Water Absorption | ≤ 0.5% | Excellent moisture resistance |
| Board Size | 600 mm × 1200 mm standard | Easy handling and installation |
| Fire Rating | Class B1 (optional) | Provides safety in residential and commercial projects |
| Surface Finish | Smooth or textured | Enhances adhesion with coatings or concrete |
Proper handling and installation ensure optimal performance and longevity of XPS boards.
Site Preparation
Ensure the surface is clean, dry, and level.
Remove debris, dust, or sharp objects that could damage the board.
Board Cutting
Use a sharp utility knife, hot wire cutter, or saw to cut boards to size.
Ensure straight, accurate edges for tight-fitting joints.
Placement
Position boards directly on the surface (floor, wall, or roof).
For overlapping joints, stagger edges to prevent thermal bridging.
Fixing
Use mechanical fasteners, adhesive, or a combination for secure placement.
Ensure boards are flush and level to prevent gaps or uneven surfaces.
Sealing
Apply joint tape or sealant at board edges to improve waterproofing and thermal efficiency.
Check for tightness and uniformity across all boards.
Final Inspection
Verify alignment, adhesion, and surface integrity.
Correct any gaps or misaligned boards before proceeding with finishing layers.
Avoid direct exposure to sunlight for prolonged periods during storage.
Do not overload boards during installation, especially in vertical applications.
Always wear protective gloves and eyewear when cutting or handling boards.
Ensure proper ventilation when using adhesives or sealants for installation.
XPS boards require minimal maintenance, but regular checks ensure maximum durability and performance:
| Maintenance Task | Frequency | Method / Notes |
|---|---|---|
| Surface Cleaning | As needed | Wipe with damp cloth; avoid abrasive cleaners |
| Inspection | Every 6–12 months | Check for moisture infiltration, cracks, or displacement |
| Joint Sealing | As needed | Reapply sealant if gaps appear |
| Protective Coating | Optional | Apply coatings in high-wear or outdoor areas |
Reliable after-sales support ensures customer satisfaction and long-term product performance:
Technical Consultation: Guidance on board selection, installation methods, and performance optimization.

| Duration | Typically 10–20 years depending on project type and material grade |
| Claim Procedure | Contact sales or service team with proof of purchase and product issue for fast resolution |
Notes:
Warranty is valid when installation guidelines are followed.
Damage due to improper handling, external forces, or chemical exposure may void coverage.
High-strength thermal insulation extruded boards are widely used in residential, commercial, and industrial projects:
Reduces heat loss in winter and heat gain in summer.
Supports roof load without deformation.
Enhances energy efficiency and indoor comfort.
Acts as a moisture barrier in external walls and basements.
Provides structural support and reduces energy loss.
Protects heating systems in underfloor applications.
Thermal insulation for cold storage, refrigeration units, and process equipment.
Suitable for high-load platforms and machinery bases.
Compared to conventional insulation materials such as mineral wool or EPS boards, high-strength XPS boards offer:
Superior Compressive Strength: Handles higher loads without deformation.
Moisture Resistance: Minimal water absorption prevents mold or rot.
Long-Term Durability: Maintains thermal and structural performance over decades.
Ease of Installation: Lightweight and easy to cut, transport, and fit.
Energy Efficiency: Reduces heating and cooling costs significantly.
Proper packaging and transport ensure boards arrive undamaged and ready for installation:

| Bulk Carton | 50–200 pcs | Ideal for large construction projects |
| Protective Film | Optional | Prevents scratches or moisture damage during transport |
| Palletized Loads | Standardized | Facilitates safe shipping and storage |
Transport Recommendations:
Avoid stacking heavy objects on boards.
Keep boards dry and protected from direct sunlight or rain.
Handle gently to prevent chipping or edge damage.
