Product Advantage
Thermal Efficiency
1. Insulation Properties:
- XPS foam boards have excellent insulation properties, reducing heat loss and improving the efficiency of the underfloor heating system. This means that more heat is directed upwards into the room rather than being lost downwards into the ground or the structure below.
2. Energy Savings:
- Because XPS foam boards provide superior insulation, the heating system requires less energy to maintain the desired temperature. This results in lower energy bills and a more sustainable heating solution.
Structural Benefits
3. High Compressive Strength:
- XPS foam boards are known for their high compressive strength, which means they can withstand significant loads without deforming. This makes them suitable for use under various types of flooring, including tile, laminate, and hardwood.
4. Durability:
- XPS is resistant to moisture, mold, and decay, ensuring a long lifespan for the underfloor heating system. This durability makes it a reliable choice for both residential and commercial applications.
Installation Advantages
5. Ease of Installation:
- XPS foam boards are lightweight and easy to cut, making them simple to install. This can reduce installation time and labor costs.
6. Compatibility:
- These foam boards are compatible with various types of underfloor heating systems, including electric and hydronic (water-based) systems. This versatility allows for a wide range of applications.
Comfort and Safety
7. Uniform Heat Distribution:
- Underfloor heating systems with XPS foam boards provide a consistent and uniform heat distribution across the floor. This eliminates cold spots and enhances overall comfort.
8. Health Benefits:
- Radiant heat from underfloor systems reduces air movement, which can help minimize the distribution of dust and allergens. This can be beneficial for people with allergies or respiratory conditions.
Space Efficiency
9. More Usable Space:
- Unlike traditional radiators or heating units, underfloor heating systems do not take up wall or floor space. This allows for more flexible interior design and furniture placement.
Environmental Impact
10. Eco-Friendly:
- XPS foam boards can be manufactured with eco-friendly materials and processes. Additionally, the improved energy efficiency of the heating system contributes to a reduced carbon footprint.

Product Operate Guide
1. Materials:
- XPS foam boards
- Underfloor heating system (electric or hydronic)
- Vapor barrier or damp-proof membrane (if necessary)
- Staple gun (for securing heating pipes or cables, if needed)
- Roller (for smoothing out vapor barrier)
Step-by-Step Construction Guide
1. Preparation
1. Clean the Subfloor:
- Ensure the subfloor is clean, dry, and level. Remove any debris, dust, or protrusions.
2. Install Vapor Barrier:
- If required, lay down a vapor barrier or damp-proof membrane to prevent moisture from affecting the insulation. Overlap the edges and tape them down securely.
2. Install XPS Foam Boards
3. Measure and Cut XPS Boards:
- Measure the floor area and cut the XPS foam boards to fit using a utility knife or saw. Ensure the cuts are precise to avoid gaps.
4. Lay XPS Boards:
- Lay the XPS boards on the subfloor, ensuring they fit snugly together. Use adhesive or tape to secure the boards in place and prevent movement.
5. Seal Gaps:
- Ensure all gaps between the boards are sealed. You can use tape or additional adhesive to fill any minor gaps.
3. Install Underfloor Heating System
6. Layout Heating Pipes or Cables:
- For electric systems, lay out the heating cables according to the manufacturer’s instructions. For hydronic systems, lay out the heating pipes.
- Ensure the spacing is even to provide uniform heat distribution.
7. Secure Heating Elements:
- Secure the heating pipes or cables using clips, staples, or a fixing mat as recommended by the system manufacturer.
8. Connect to Manifold or Power Source:
- For hydronic systems, connect the pipes to the manifold. For electric systems, connect the cables to the thermostat and power source.
4. Apply Screed or Self-Leveling Compound
9. Mix Screed/Compound:
- Prepare the screed or self-leveling compound according to the manufacturer’s instructions.
10. Apply Screed/Compound:
- Pour the screed or self-leveling compound over the heating elements, ensuring an even distribution. Use a trowel to smooth it out and remove any air bubbles.
11. Allow to Cure:
- Allow the screed or compound to cure fully. This may take several days, depending on the product used. Follow the manufacturer's curing time recommendations.
5. Install Floor Covering
12. Prepare Floor Covering:
- Once the screed or self-leveling compound is fully cured, prepare your chosen floor covering (tiles, laminate, hardwood, etc.).
13. Lay Floor Covering:
- Install the floor covering as per the manufacturer's guidelines. Ensure the heating system is off during this process to prevent any movement or damage.
14. Final Connections and Testing:
- Connect any remaining electrical components and test the underfloor heating system to ensure it is working correctly. Follow the manufacturer's testing procedures.
Final Considerations
- Testing and Calibration:
- Ensure the system is tested and calibrated to the desired temperature settings before regular use.
- Maintenance:
- Regularly check the system for any signs of wear or issues and perform necessary maintenance as recommended.
By following these steps, you can ensure a successful installation of an underfloor heating system with XPS foam board construction, providing efficient and comfortable heating for your space.
