Tiling Over Cablewarm® Underfloor Heating

Once the Cablewarm® heating mats/cables are laid, suitable protection boards should be used to prevent any possible damage during the tiling phase.

A good quality rapid setting, flexible tile adhesive should be laid evenly and spread in the same direction as the cables are running, in order to fully encapsulate the heating cable, leaving no air spaces.
NOTE: To avoid any potential damage to the Cablewarm® heating cables that may be caused by using a steel notched trowel, Floor Heating Limited strongly recommend using a plastic notched trowel for this operation.

An alternative method of installation would be to pour a thin layer of flexible, self-levelling compound (sometimes referred to as latex) to cover the heating cable to give a level surface prior to laying the tile adhesive. Once the levelling compound has dried (12 – 24 hours) tiles can be laid as normal using a good quality flexible tile adhesive.

Wood Or Laminated Engineered Wood Flooring Over Cablewarm® Underfloor Heating Mats or Cables

A flexible, rapid setting, Levelling Compound suitable for under floor heating systems is required to completely encapsulate the heating cable; it is recommended that at least 5-6mm be applied to give adequate cover to the heating cables.

Follow manufacturer’s instructions for flooring installation: however for best results, if using an acoustic layer under the flooring, then it is recommended that a low tog rated insulation/acoustic layer be selected in order that heat from the Cablewarm® underfloor heating system is not thermally blocked.

Soft Flooring Like Carpet Or Vinyl Types Over Cablewarm® Floor Heating Mats or Cables

A flexible, rapid setting, Levelling Compound suitable for under floor heating systems is required to completely encapsulate the heating cable; it is recommended that at least 10mm be applied to give adequate cover to the heating cables.

For carpets: it is recommended that a low tog rated underlay be used in order that heat from the Cablewarm® underfloor heating system is not thermally blocked.
