Suitability
Due to their high thermal conductivity and low thickness, ceramic tiles are one of the best floor finishes for use with underfloor heating. In all cases, a quality 2 part flexible adhesive such as BAL Fastflex should be used. When laid on screed floor heating, a de-coupling membrane such as Schluter Ditra should be used. This prevents contraction cracks in the screed being transmitted through the floor covering.

Stone can be fitted on to a floating floor that exhibits minimal deflection, so installing the floor heating over a flat level surface using insulation material with high compressive strength is essential. Special substrates such as Fermacell or Versapanel are beneficial for tiling on floating floors but manufacturer’s guidance should be followed.
