Radiant floor heating and thermal performance
Every type of parquet can be installed over radiant floor heating under some conditions.
We recommend for solid parquet thickness 13-17mm and for engineered parquet 10-15mm only.
Wood is a poor conductor is therefore has an insulating effect. As a result, floors with radiant heating are warm to the touch. Therefore, we suggest using bonding (install full glued ) for an optimal heat flow.
Radiant floor heating systems are offered by the producers as complete systems. They are also suitable for the installation of parquet. The system must be equipped with a dew point sensor and the minimum surface temperature in cooling mode mustn't fall below 19 °C and max. temp not exceed 26 °C (also to ensure the thermal comfort of the room).
Shrinking and swelling of wood floors / moisture
Moisture is harmful to every kind of wood floor.
The sub floor's moisture content must be checked before installing the parquet. Due to their open cell structure, certain types of wood have a higher capacity to absorb and release moisture than others.
It is important to keep this characteristic in mind when cleaning installed floors. It is generally recommended to apply polish to lacquered surfaces and maintenance oils on oiled floors maintenance to protect the floor.
Parquet and radiant Floor Heating Systems
Solid parquet is not suitable for installation over electric heated floors.
Only engineered parquet floor can be installed on electric floor heating under some strict rules.
However, the surface temperature must be controllable and must not exceed a temperature of 27°C (80°F) in any part for the entire life-span of the parquet.
Wood does not draw warmth away from the feet, as you may experience with tile floors, guaranteeing maximum comfort. This is what makes wooden floors so comfortable.
For types of wood highly susceptible to shrinkage and swelling (e.g. beech and maple), larger gaps and holes may appear during seasons when the heat is turned on. By maintaining a healthy room climate of 20-22°C (68-72°F) and a relative humidity level of approx. 45-60% these effects may be prevented or minimized . The use of an air humidifier when the heating system is in use is also recommended for the well-being of the occupants.
Choosing a wood floor
Multi-layer parquet floors are less liable to shrinkage and swelling than solid wood floors but both can be used. All bonded and floating parquet floors from Expert Parchet are suitable for installation with radiant floor heating systems. Without the use of special installation techniques, floors with a thermal resistance of R ≤ 0.15 m2 K/W are suitable.
Special considerations when laying parquet over radiant floor heating systems

Guidelines for installing parquet on new cement screeds
Test the recently installed radiant floor heating system to ensure it is functioning properly: the installation company must control and record the functioning of the heating system.
However, in this test only the proper functioning of the system is documented. Under no circumstances should the screed be dried for installation based on the required moisture levels (ready for installation).
The floor heating and CM measurements in large part follow specific national requirements (DIN standards, Ö standards, etc.). Therefore, they are imperative in every circumstance.
The following points must be followed in accordance with manufacturing standards and SIA norms:
