Parquet flooring is a timeless and elegant choice for interiors, but when combined with underfloor heating, it’s important to select the right type of parquet that works harmoniously with the heating system. Here’s what you need to know when choosing parquet for heated floors.
1. Opt for Engineered Wood Parquet
While solid wood parquet is beautiful, engineered wood is the better option for underfloor heating. Engineered wood consists of multiple layers of wood veneer and a solid wood top layer. This structure makes it more dimensionally stable and less prone to expanding or contracting due to temperature changes.
- Solid wood can warp or crack when exposed to fluctuations in heat and humidity.
- Engineered wood handles these variations better, providing long-term durability without compromising on the natural wood appearance.
2. Wood Species Selection
Not all wood species react the same to temperature changes. Some woods are more stable and better suited for heated floors. When choosing the top layer of engineered parquet, opt for dense, stable woods like:
- Oak: Known for its durability and stability.
- Walnut: A luxurious, stable hardwood that performs well with heating systems.
- Teak: Naturally resistant to moisture and temperature fluctuations.
Woods like maple or beech tend to expand and contract more, making them less ideal for underfloor heating.
3. Thickness Matters
The thickness of the parquet plays a crucial role in how well the heat transfers through the floor. For heated floors, the parquet should generally have a total thickness of 15 mm or less to allow efficient heat conduction. The top veneer layer (the real wood surface) should be between 2 to 4 mm, ensuring a balance between durability and thermal performance.
- Thicker parquet may insulate the heat, reducing the system’s efficiency.
- Thinner options allow faster and more even heat distribution.
4. Moisture and Heat Resistance
Parquet flooring must withstand the dual impact of heat and humidity fluctuations from underfloor heating systems. Look for parquet that has been treated or manufactured with moisture and heat resistance in mind. This will help prevent issues like warping, cracking, or shrinking over time.
- Ensure that the adhesive used during installation is compatible with heated floors and can withstand higher temperatures.
5. Installation Method
The floating installation method, where parquet planks are clicked together without being glued directly to the subfloor, can be problematic for underfloor heating because it leaves air gaps that reduce heat transfer efficiency. Instead, opt for a glue-down installation, which improves thermal conductivity by creating a solid bond between the parquet and the subfloor.
6. Thermal Conductivity
Parquet flooring has relatively low thermal conductivity compared to tiles or stone, but engineered wood is more heat-friendly than solid wood. To maximize heat efficiency, choose parquet flooring with a low thermal resistance value. This ensures better heat transfer from the underfloor system to your living space.
7. Compatible Underlays
If you’re using an underlay beneath your parquet, ensure it’s specifically designed for use with underfloor heating. The underlay should have good thermal conductivity and low thermal resistance to ensure the heat passes through effectively.
8. Maintenance and Care
Underfloor heating can cause slight drying of the wood, so it’s essential to maintain proper humidity levels (ideally between 40-60%) in your home. Regular care, like cleaning with products suited for wood, will ensure the parquet remains in excellent condition.
Conclusion
Engineered wood parquet is the ideal choice for underfloor heating due to its superior stability and compatibility with fluctuating temperatures. Opt for thinner planks with species like oak or walnut, and use glue-down installation for optimal heat transfer. By selecting the right materials and installation methods, you can enjoy the warmth and elegance of parquet flooring in a cozy, heated home.
