Product Advantage
1. Energy Efficiency
- Superior Insulation: XPS foam boards have excellent thermal insulation properties, reducing heat loss through the floor.
- Lower Operating Costs: Better insulation means the heating system uses less energy to maintain the desired temperature, leading to lower energy bills.
2. Enhanced Comfort
- Even Heat Distribution: Underfloor heating provides consistent and uniform heat distribution across the entire floor, eliminating cold spots.
- Comfortable Warmth: The system warms the room from the ground up, providing a more natural and comfortable heat compared to traditional radiators.
3. Space Saving
- No Radiators Needed: With underfloor heating, there's no need for wall-mounted radiators, freeing up wall and floor space for furniture and décor.
- Aesthetic Flexibility: This allows for more flexible interior design options.
4. Improved Air Quality
- Reduced Dust Circulation: Unlike forced air systems, UFH does not circulate dust and allergens, leading to better indoor air quality.
- Healthier Environment: This can be particularly beneficial for people with allergies or respiratory conditions.
5. Silent Operation
- No Noise: Underfloor heating systems operate silently, in contrast to the noise that can be generated by traditional radiators and HVAC systems.
6. Durability and Longevity
- Long-Lasting Materials: XPS foam boards are durable and moisture-resistant, contributing to the longevity of the underfloor heating system.
- Low Maintenance: The combination of XPS boards and UFH systems typically requires less maintenance compared to conventional heating systems.
7. Environmental Benefits
- Eco-Friendly: The energy efficiency of UFH systems, combined with the insulating properties of XPS foam boards, results in a lower carbon footprint.
- Sustainable Living: Reduced energy consumption aligns with sustainable living practices.
8. Compatibility
- Versatile Application: Underfloor heating with XPS foam boards is compatible with various types of flooring, including tile, stone, laminate, and even carpet.
- Adaptable Systems: These systems can be installed in new constructions as well as retrofitted in existing buildings.
9. Quick Installation
- Ease of Installation: XPS foam boards are lightweight and easy to handle, making the installation process quicker and more straightforward.
- Prevents Thermal Bridging: The insulation properties of XPS boards prevent thermal bridging, ensuring efficient heat retention.

Product Operate Guide
1. Preparation
Materials Needed:
- XPS foam boards
- Underfloor heating pipes or cables (for hydronic or electric systems)
- Clean the Subfloor: Ensure the subfloor is clean, dry, and free from any debris or sharp objects.
- Check Level: Verify that the subfloor is level. If necessary, use a self-leveling compound to even out the surface.
3. Install Edge Insulation
- Edge Strips: Install edge insulation strips around the perimeter of the room. This helps prevent heat loss through the walls and allows for expansion of the screed.
4. Lay the XPS Foam Boards
- Cut to Size: Cut the XPS foam boards to fit the room dimensions using a utility knife.
- Place Boards: Lay the XPS foam boards on the subfloor, ensuring they fit snugly together with no gaps. Use adhesive or tape to secure them in place if necessary.
5. Install the Heating System
For Hydronic (Water-Based) Systems:
- Pipe Layout: Plan the layout for the heating pipes. Common patterns include serpentine or spiral configurations.
- Fixing the Pipes: Attach the heating pipes to the XPS boards using pipe clips or a fixing system, ensuring even spacing (usually 100-200 mm apart). Make sure to avoid sharp bends to prevent pipe damage.
- Connect to Manifold: Connect the pipes to the manifold according to the manufacturer’s instructions.
For Electric Systems:
- Cable Layout: Lay out the heating cables or mats according to the planned layout. Follow the manufacturer's guidelines for spacing.
- Fixing the Cables: Secure the cables to the XPS boards using adhesive, tape, or a staple gun.
6. Install Heat Spreader Plates (If Required)
- Position Plates: Lay heat spreader plates over the pipes or cables. These plates help distribute heat more evenly across the floor surface.
- Secure Plates: Ensure the plates are securely in place and make good contact with the heating elements.
7. Test the System
- Pressure Test (Hydronic): Conduct a pressure test to check for any leaks in the pipework.
- Electrical Test (Electric): Perform an electrical resistance test to ensure there are no faults in the cables.
8. Apply Screed or Self-Leveling Compound
- Mix Screed: Prepare the screed or self-leveling compound according to the manufacturer’s instructions.
- Pour Screed: Pour the screed over the XPS boards and heating elements, ensuring an even coverage. The typical thickness is around 50-70 mm for screed.
- Level Surface: Use a trowel to level the surface and remove any air bubbles.
9. Cure the Screed
- Curing Time: Allow the screed to cure properly. This can take several days to a few weeks, depending on the type of screed used. Follow the manufacturer's guidelines for curing times.
10. Install Final Flooring
- Final Floor Covering: Once the screed is fully cured, you can install the final flooring (tiles, laminate, hardwood, etc.). Ensure the flooring material is suitable for use with underfloor heating.
11. System Commissioning
- Initial Heating: Gradually heat the system for the first time to avoid thermal shock to the screed. Increase the temperature incrementally over a few days.
- Thermostat Setup: Install and configure the thermostat to control the underfloor heating system effectively.
