You need a parquet floor with low thermal resistance and good dimensional stability. Glued parquet, such as mosaic, industrial, or prefabricated plywood, usually performs better than floating or solid wood floors. Thermal resistance is typically around R = 0.06–0.09 m2K/W for glued parquet and R = 0.15–0.18 m2K/W for floating or solid wood parquet. Double-layered parquet with birch plywood backing is often a strong choice because it combines efficiency with stability.

When installing an engineered flooring, a water-free adhesive (two-component epoxy-polyurethane or polyurethane, single-component or two-component, directly spreading on the subfloor) must be used and able to maintain its elasticity characteristics over time.

We maintain engineered flooring by keeping the air temperature between 15-30°C and relative humidity within 45-65%. The parquet surface temperature should stay below 26-27°C. We avoid placing thick carpets to prevent heat concentration and gaps. For underfloor heating systems with cooling functions, we include anti-vapour and anti-condensation systems to prevent moisture-related issues.

We consider thermal resistance, dimensional stability, and compatibility with underfloor heating when selecting parquet flooring. Thermal resistance depends on the wood type and thickness. Glued parquet, such as mosaic, industrial, or prefabricated plywood, has lower resistance (R = 0.06 - 0.09 m2K/W), while floating or solid wood parquet has higher resistance (R = 0.15 - 0.18 m2K/W). For optimal energy efficiency and stability, double-layered parquet with birch plywood backing is an excellent choice.

For low-temperature heating installations (maximum liquid temperature of 40-45°C), pipes must be embedded in a cement or anhydrite-based conglomerate to ensure optimal heat transmission. Subfloor drying: After 28 days, start the heating system, increasing the water temperature by 2-4°C per day until it reaches 40-45°C. Maintain this for 1-2 weeks, then gradually lower the temperature by 5°C per day. Leave the system off for 5-10 days, then restart and gradually increase the temperature. Check residual humidity: less than 1.7% CM for cement screed and 0.2% CM for anhydrite screed.

We recommend using a water-free adhesive, such as two-component epoxy-polyurethane or polyurethane (single or two-component), for installing engineered flooring. These adhesives are designed to maintain their elasticity over time.

Usually, the engineered flooring has exceptional dimensional stability performance, even in adverse conditions. The wood, by its nature, is subject to dimensional variations depending on the humidity and the ambient temperature. In order for this natural behaviour not to generate an undesirable effects on the floor, the environmental climate must always be maintained within the recommended limits: The air temperature should be between 15 and 30 ° C and the relative humidity of the air (especially) should be maintained between 45% and 65%, this range of values ​​corresponding, among other things, to the conditions conducive to normal health and hygiene for humans. In order to guarantee the stability of the parquet and especially the human physiological demands, the temperature on the surface of the parquet should never exceed 26 - 27 ° C (it should be mentioned that modern installations, operating at low temperature, provide remarkable environmental comfort at floor level from about 24 to 25 ° C). In order to avoid heat concentrations and, consequently, the appearance of gaps or deformation of the parquet, in addition to a low thermal efficiency, it is recommended not to cover the wooden floors with thick carpets or other materials that have a high thermal resistance. Bear in mind that pre-laminated engineered flooring, subjected to a particular and intense heating period, may develop slight shrinkage and small joints between the elements, which will disappear once the underfloor heating installation is turned off. For underfloor heating installations that also have a cooling function, all necessary anti-vapour and anti-condensation systems must be incorporated in order to categorically avoid condensation at any level of the screed composition. The lack of such systems can cause the parquet to absorb moisture and, consequently, it suffers dimensional deformations.

You prepare the subfloor with a cement- or anhydrite-based layer so heat transfers efficiently. After about 28 days of drying, you commission the system gradually: increase the water temperature by 2–4°C per day until it reaches 40–45°C, hold it there for 1–2 weeks, then reduce it by 5°C per day. Leave the system off for 5–10 days before restarting it slowly.

Timing depends on the room size, the pattern you choose, and the condition of your subfloor. A simple installation can be completed quickly, while larger rooms or more detailed patterns take longer. We confirm the likely timescale after reviewing your project.

Yes. We sand and seal worn parquet floors to improve appearance and protect the wood. If needed, we also assess repairs and subfloor work before restoration begins.

Yes. We can supply the parquet, prepare the subfloor, install the floor, and carry out sanding and sealing when required. You get one service from start to finish.

We are based in London and work across Greater London and other UK locations depending on the size and scope of the project. We handle both domestic and commercial work.
