Yes. You need to take specific precautions:
Before you start work, check with your retailer that the flooring is compatible with your subfloor.
We do not recommend using jatoba, beech or maple species in such situations, and the heat resistance of floor coverings and any intermediate layers (such as acoustic underlayers) should not exceed 0.15 W/m²K.
Subject to these conditions, the surface temperature of finished floors should not exceed 28°C.
LAYING ON LOW-TEMPERATURE HEATED FLOORS
Hydronic radiant floor heating:
- The covering layer should use a suitable concrete with a minimum thermal conductivity of 1.2 W/m²K. It may be combined with a separate layer in the case of type C heated floors.
- The water temperature must not exceed 40°C.
- The system must be carefully regulated, particularly when it is switched on for the first time, but also throughout its working life, to ensure this temperature is not exceeded.
Electric radiant floor heating:
- The system also allows the floor to be floated with an underlayer.
- We advise against using carpets and low-lying furniture, as these can significantly affect system performance.
- The covering layer above the heating elements should be 5 to 6 cm thick.
- The temperature must be carefully regulated, particularly when the system is switched on for the first time, but also throughout its working life, to ensure that it does not rise too quickly.
LAYING ON A REVERSIBLE (HEATING/COOLING) FLOOR
- You MUST glue the full surface to the underfloor using an MS polymer adhesive (e.g. Presto PM) without an underlayer.
- The system must ensure that heat is evenly distributed across the surface.
- Fluid temperatures must be controlled by automatic probes to prevent underfloor condensation from forming.
- The circuit must limit the fluid output temperature to between 18 and 22°C. The system installer must comply with this requirement.
- Heat emissions must not exceed 100 W/m2.
- In summer, individual room thermostats should not be set below 22°C. The cooling system will not switch on until the ambient temperature is greater than or equal to 25°C.
