Floor heating

When laying KRONOTEX flooring, make sure that the subfloor is suitable. Suitable are, for example:

  1. Old flooring such as PVC (provided it is fully glued and not floating), wood floors, ceramic (dry), linoleum
  2. Cement screed (max. residual moisture of 2.0 CM%)
  3. Dry and floating anhydrite screed (max. residual moisture of 0.3 CM%)
  4. Magnesite screed (max. residual moisture of 3.0 CM%)
  5. Have a floor installer measure the residual moisture.

High-moisture areas (bathrooms, laundry rooms, saunas etc.), carpeting and xylolith are not suitable.

The subfloor must be absolutely dry, level, solid and clean. Small variations in flatness can be evened out by an underlayment (to attenuate footfall sound); spots higher than 3 mm per metre need to be ground down, and low spots must be filled in with a levelling compound.

It is no problem to lay KRONOTEX flooring over hydronic radiant floor heating as long as you follow the special instructions. The properties of our laminates – such as favourable thermal conductivity, natural underfoot warmth and uniform distribution of the surface temperature – actually help to reduce heating costs.

The preparations for laying laminate flooring over floor heating include:

  1. Make sure to warm mineral subfloors before laying to prevent unacceptable amounts of moisture from being released.
  2. Have a heating installer assess the effects of heating.
  3. It is very important to allow for warm-up and cool-down phases. When laying, the surface temperature of the floor should be at least 15°C.
  4. In order to keep moisture and water vapour out, lay a PE membrane underneath (0.2 mm thick).
  5. To attenuate footfall noise and provide thermal insulation, underlay with PE foam or another suitable material. Suitable as acoustic insulation is foamed PE, a KRONOTEX underlayment mat or KRONOTEX laminate flooring with Sound Design acoustic underlayment.
  6. When starting to heat each winter, gradually increase the floor heating by 5°C each day until it reaches the optimal flow temperature. The temperature of the floor surface should not exceed 26°C.
  7. If you are planning to install electric underfloor heating, please ask the manufacturer to confirm that it is compatible with laminate flooring. If this is the case, you can use our floors without any reservations.
