Product Advantage
1. Exceptional Thermal Insulation: Thanks to its closed-cell structure, the extruded plastic board boasts remarkably low thermal conductivity. This effectively impedes the downward transfer of heat, significantly enhancing the thermal efficiency of floor heating systems and reducing energy consumption.
2. Robust Strength and Stability: The extruded plastic board exhibits high strength and excellent pressure resistance, making it resilient against external forces. It maintains stability over time, ensuring the ground foundation remains flat and solid 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 infiltration into the floor heating system. This safeguards against heat preservation loss and system failures caused by moisture.
4. Environmentally Friendly and Durable: Crafted from non-toxic and eco-friendly materials, extruded plastic boards boast resistance to aging, stable chemical properties, and a long lifespan. They do not decompose or release hazardous substances, aligning with modern building standards for green, energy-efficient construction.
5. Structural Support: Certain designs of extruded plastic boards can serve as stable carriers for floor heating pipes. This feature provides reliable support, preventing pipe sinking or displacement and ensuring the system's longevity.
6. Convenient Installation: Lightweight and easily cuttable, extruded panels streamline installation processes. They can be tailored to specific sizes as needed and seamlessly integrated into the underfloor heating system's bottom layer, offering convenience while saving construction time and costs.

Product Operate Guide
Step 1: Preparation
1.Cleaning the Floor: Ensure the floor is flat, dry, and free of debris. Remove all dust, stones, and other foreign objects that could affect the paving quality.
2.Measuring and Cutting: Measure and use special tools (such as an electric disc saw) to accurately cut the extruded plastic board to fit the actual room size.
Step 2: Laying Boundary Insulation Strips
Install boundary insulation strips around the walls and at special locations like column footings and door frames. This prevents heat loss and ensures the extruded panels fit seamlessly against the walls.
Step 3: Laying the Extruded Panels
1. Following the design drawings, start laying the extruded panels from one corner of the room, ensuring each panel is tightly spliced with no gaps to maintain insulation effectiveness.
2. If floor heating pipes need to be installed, use a special hole opener to create grooves in the extruded plastic board. The depth and spacing of the grooves should be according to the floor heating design scheme.
3. During the laying process, ensure a proper overlap between the boards and the boundary insulation strips to maintain effective insulation.
Step 4: Fixing and Protection
1. If needed, use special fixings or nylon ties to reinforce the extruded board to prevent displacement during construction and use.
2. After laying the floor heating pipes, ensure they are correctly fixed in the extruded sheet grooves without being squeezed or bent.
Step 5: Sealing and Checking
1. Once the floor heating pipes are laid and pass the pressure test, seal all seams and openings of the extruded plastic board with special sealing tape or caulking to prevent moisture ingress.
2. Conduct a thorough check of the installation quality of the extruded plastic board to ensure there are no omissions, damage, or loose parts.
Step 6: Subsequent Construction
1. Lay a reflective membrane or covering above the extruded panels to reflect heat back into the room and provide a base for subsequent floor tiling or flooring.
2. After completing all insulation and protection measures, proceed with installing concrete backfill or floor decoration materials.
