Product Advantage
1. Energy Efficiency
- Thermal Insulation: XPS foam boards have excellent thermal insulation properties, reducing heat loss through the floor. This helps maintain consistent indoor temperatures and reduces the energy required to heat the space.
- Uniform Heat Distribution: Underfloor heating provides even heat distribution, ensuring no cold spots in the room. This uniformity improves overall energy efficiency compared to traditional heating systems, which often create temperature gradients.
2. Comfort
- Even Heating: The even distribution of heat creates a comfortable living environment. Floors stay warm, making it pleasant to walk barefoot, especially in colder climates.
- Radiant Heat: Unlike forced air systems, underfloor heating provides radiant heat, which warms objects and people directly rather than just the air. This type of heating is often perceived as more comfortable.
3. Aesthetics and Space Saving
- Invisible System: Underfloor heating systems are hidden beneath the floor, eliminating the need for radiators or heating vents. This allows for more flexible interior design and furniture placement.
- Increased Usable Space: With no need for bulky radiators, more wall and floor space is available for use.
4. Improved Indoor Air Quality
- Reduced Air Movement: Underfloor heating reduces the circulation of dust and allergens compared to forced air systems, leading to improved indoor air quality.
- No Dust Traps: Without radiators or vents, there are fewer places for dust to accumulate.
5. Installation and Durability
- Ease of Installation: XPS foam boards are lightweight and easy to cut and shape, simplifying the installation process. They are often used as an insulating layer in underfloor heating systems.
- Durability: XPS foam boards are moisture-resistant and have high compressive strength, ensuring long-term performance and durability. This is particularly important in areas with high foot traffic or where floors may be exposed to moisture.
6. Cost-Effectiveness
- Lower Operating Costs: The energy efficiency of underfloor heating systems, combined with the insulating properties of XPS foam boards, leads to lower heating bills over time.
- Long-Term Savings: Although the initial installation cost can be higher than traditional heating systems, the long-term savings in energy costs and increased property value often outweigh the initial investment.
7. Environmental Benefits
- Reduced Energy Consumption: Efficient heating systems reduce energy consumption, which in turn lowers greenhouse gas emissions.
- Sustainable Materials: XPS foam boards are often made from recyclable materials, contributing to more sustainable construction practices.
Combining underfloor heating with XPS foam board construction leverages the strengths of both systems to create an efficient, comfortable, and durable heating solution suitable for various types of buildings and climates.

Product Operate Guide
1. Preparation:
- Clear the Area: Ensure the floor area is clean, dry, and free of debris. Remove any existing floor coverings and clean the surface thoroughly.
- Level the Subfloor: Check the subfloor for any uneven spots and level them out. This can be done using a leveling compound if necessary.
2. Install a Vapor Barrier:
- Lay a Vapor Barrier: If moisture protection is needed, lay a vapor barrier across the subfloor to prevent any dampness from affecting the insulation and heating system. Overlap the edges and tape them securely.
3. Install XPS Foam Boards:
- Cut the Boards: Measure the floor area and cut the XPS foam boards to fit. They should fit snugly without any gaps.
- Lay the Boards: Place the XPS foam boards on the subfloor. Ensure they are laid out evenly and cover the entire area where the underfloor heating will be installed.
- Fix the Boards: Secure the XPS foam boards to the subfloor using appropriate adhesive or mechanical fixings as recommended by the manufacturer.
4. Lay the Underfloor Heating System:
- Electric Heating Mats or Cables:
- Roll Out the Mats or Cables: Lay the electric heating mats or cables directly on top of the XPS foam boards according to the manufacturer's layout plan.
- Fix in Place: Secure the mats or cables to the boards using tape or clips provided by the heating system manufacturer.
- Hydronic (Water-Based) Heating Pipes:
- Install Pipe Fixing Systems: If using water-based heating, first install the pipe fixing systems (such as clip rails) on top of the XPS foam boards.
- Lay the Pipes: Lay the heating pipes according to the design plan, securing them in the clip rails. Ensure they are evenly spaced for uniform heat distribution.
5. Connect the Heating System:
- Electrical Connections: For electric systems, connect the heating mats or cables to the thermostat and power supply according to the manufacturer's instructions. Ensure all electrical work complies with local codes and regulations.
- Hydronic Connections: For water-based systems, connect the pipes to the manifold and ensure all connections are secure and leak-free. Pressure test the system to check for leaks before proceeding.
6. Install a Thermal Barrier:
- Thermal Barrier Layer: Depending on the system, you might need to install a thermal barrier layer, such as a thin layer of screed or self-leveling compound, on top of the heating elements to protect them and aid in heat distribution.
7. Lay the Flooring:
- Install Flooring: Once the heating system and any thermal barrier layers are in place and cured, install the final floor covering. This could be tile, laminate, hardwood, or carpet, depending on your preference and the compatibility with the heating system.
8. Test the System:
- Initial Test: After the flooring is installed, test the underfloor heating system to ensure it is functioning correctly. Follow the manufacturer’s instructions for the initial heating process to avoid thermal shock to the new flooring.
- Adjust Settings: Set the thermostat to the desired temperature and adjust settings as necessary for optimal comfort and efficiency.
