High-Thermal XPS Board for Floor Heating

Product Overview

Whether you're constructing a new home, renovating a commercial space, or upgrading your heating system, this high-thermal XPS board ensures uniform heat distribution, reduced energy consumption, and long-term durability. Its unique combination of thermal properties and structural stability addresses the key challenges faced in floor heating applications, providing a reliable solution that meets the demands of modern construction standards.

Material Composition

The High-Thermal XPS Board for Floor Heating is crafted from premium-grade extruded polystyrene, produced using advanced CO₂ foaming technology that eliminates the use of harmful hydrochlorofluorocarbons (HCFCs), resulting in a product with zero ozone depletion potential . This eco-friendly manufacturing process creates a homogeneous closed-cell structure that forms the foundation of the board's exceptional thermal performance. What sets this material apart is the integration of a 0.22mm thick aluminum film soaking layer on its surface, a critical component that significantly enhances heat transfer efficiency . The aluminum layer acts as a superior heat reflector and distributor, ensuring that heat from the underfloor pipes is evenly spread across the entire floor surface rather than being lost downward. The core XPS material itself is engineered to maintain consistent thermal properties even under prolonged use, with a composition that includes recycled content averaging 20% , aligning with sustainable building practices.

Superior Thermal Conductivity

At the heart of this product's performance is its impressive thermal conductivity of ≤0.039 W/(m·K) , a key metric that determines how effectively the board retains and transfers heat. This low thermal conductivity means that heat generated by the underfloor heating system is efficiently directed upward into the living space rather than being wasted through downward dissipation into the subfloor. Compared to traditional insulation materials, this high-thermal XPS board reduces heat loss by up to 30%, resulting in significant energy savings and lower heating costs over time.

Enhanced Heat Distribution

The integrated aluminum film soaking layer plays a crucial role in achieving uniform heat distribution. This layer ensures that heat from the heating pipes is spread evenly across the entire board surface, eliminating cold spots and creating a comfortable living environment. The aluminum film also features infrared reflection properties, which help to retain heat within the room, further enhancing energy efficiency . This feature is particularly beneficial in large spaces where maintaining consistent temperatures can be challenging.

Moisture Resistance

With a closed-cell structure boasting a ≥95% closed area percentage and a water absorption rate of ≤1.0% after 96 hours of soaking , this XPS board offers exceptional moisture resistance. This is vital in floor heating applications where exposure to moisture can lead to mold growth, structural damage, and reduced insulation performance. The board's ability to resist water absorption ensures that its thermal properties remain consistent over time, even in humid environments such as bathrooms, kitchens, and basements.

Dimensional Stability

The High-Thermal XPS Board for Floor Heating maintains excellent dimensional stability under varying temperature and humidity conditions. This stability prevents warping, shrinking, or expansion that could disrupt the integrity of the floor heating system or the flooring itself. The board's resistance to linear thermal expansion, tested according to ASTM D696 standards , ensures that it remains structurally sound throughout its service life, even with the temperature fluctuations typical in floor heating applications.

Easy Installation

Designed with practicality in mind, the board features pre-cut grooves at standard intervals, specifically engineered to accommodate heating pipes of various sizes . This design simplifies the installation process, reduces labor time, and ensures precise placement of the heating elements. The lightweight nature of the XPS material also makes handling and maneuvering during installation easier, reducing worker fatigue and improving efficiency.

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.
