Finished multi-layered parquets are the only type of parquet that is recommended for laying on substrates with built-in underfloor heating, since, thanks to their multi-layered structure, they have the ability to conduct heat well. When installing parquet on underfloor heating, it is necessary to follow the rules of a special protocol, which are known to professional parquet installers. In order for parquet on underfloor heating to retain its original properties and appearance even after a long time, it is important not to exceed the maximum permitted temperature of the underfloor heating. The temperature on the surface of the parquet should never be more than 24 C, which corresponds to the usual room temperature of the air in the room.
The reaction of wood to improper use of underfloor heating can be manifested in the formation of larger joints between parquet boards and longitudinal and/or transverse cracking of the cover lamella.
