Product Advantage
1. Outstanding Thermal Insulation Performance: Thanks to its closed-cell structure, the extruded plastic board exhibits remarkably low thermal conductivity. This feature effectively inhibits the downward transfer of heat, significantly enhancing the thermal efficiency of floor heating systems and reducing energy consumption.
2. Superior Strength and Stability: Extruded plastic boards boast high strength and excellent pressure resistance, rendering them resilient against external forces. They maintain stability over prolonged periods, ensuring a flat and sturdy ground foundation throughout the operation of the floor heating system.
3. Waterproof and Moisture-Resistant: With minimal water absorption properties, extruded plastic boards act as a barrier against moisture, safeguarding the floor heating system from water penetration. This feature prevents the loss of thermal insulation effectiveness and potential system failures caused by moisture.
4. Environmentally Friendly and Durable: Crafted from non-toxic, eco-friendly materials, extruded plastic boards are resistant to aging and possess stable chemical properties. They boast a long service life, remaining intact without decomposition or emitting hazardous substances, aligning with modern building standards for green energy efficiency.
5. Structural Support: Certain designs of extruded plastic boards serve as stable carriers for floor heating pipes, providing robust support and preventing pipe sinking or displacement.
6. Convenient Installation: Lightweight and easily cuttable, extruded panels can be tailored to specific sizes and effortlessly installed as the bottom layer of underfloor heating systems. This streamlined installation process saves both time and construction costs.

Product Operate Guide
Step 1: Preparation
1.Cleaning the Floor: Ensure the floor is level, dry, and free from debris. Remove all dust, stones, and other foreign objects that might affect the quality of the paving.
2.Measuring and Cutting: Measure the room and use specialized tools (such as an electric disc saw) to accurately cut the extruded plastic boards to fit the room's floor size.
Step 2: Laying Boundary Insulation Strips
Install boundary insulation strips around the walls and at specific locations like column footings and door frames. This prevents heat loss and ensures that the extruded panels fit seamlessly against the walls.
Step 3: Laying the Extruded Panels
1.Initial Laying: Following the design drawings, start laying the extruded panels from one corner of the room. Ensure each panel is tightly spliced with no gaps to maintain effective insulation.
2.Pipe Installation (if needed): If floor heating pipes are to be installed, use a special hole opener to create grooves in the extruded plastic board for the pipes. Determine the depth and spacing of these grooves according to the floor heating design scheme.
3.Lap Width Consideration: During the laying process, ensure there is sufficient lap width between the panels and between the insulation strips and the boundary to guarantee insulation effectiveness.
Step 4: Fixing and Protection
1.Reinforcement: If necessary, use special fixings or nylon ties to reinforce the extruded board, ensuring it remains in place during construction and use.
2.Securing Pipes: After laying the floor heating pipes, ensure they are correctly fixed in the grooves of the extruded sheets and are not squeezed or bent.
Step 5: Sealing and Checking
1.Sealing: After completing the floor heating pipe installation and passing the pressure test, seal all seams and openings in the extruded plastic board with special sealing tape or caulking to prevent moisture ingress.
2.Quality Check: Thoroughly check the installation quality of the extruded plastic board to ensure there are no omissions, damages, or loose areas.
Step 6: Subsequent Construction
1.Reflective Membrane: Lay a reflective membrane or covering over the extruded panels to reflect heat back into the room and provide a base for subsequent floor tiling or flooring.
2.Final Installation: Once all insulation and protection measures are complete, install concrete backfill or floor decoration materials.
