SUITABILITY OF WOODEN FLOORING WITH UNDERFLOOR HEATING
You must follow Rappgo's laying instructions carefully for every floor we supply. The instructions will say what types of wood are not suitable for underfloor heating. This applies particularly for Beech and Maple. These shrink and swell more than other types of wood, which can cause damage to the floor. This damage is not considered a manufacturing defect and will not be accepted as a complaint. We do not therefore recommend Beech and Maple in conjunction with underfloor heating. If you still decide to lay Beech or Maple flooring, Rappgo will disclaim liability for any damage that occurs.
It is important that the surface temperature of the floor does not exceed 27°C and that the relative air humidity lies between 30 and 60%.
