All Pinnacle Underfloor Heating Mats can work with many floor finishes and coverings.

Vinyl – Fully encapsulate the Pinnacle Mat within a 10mm bed of flexible smoothing compound, to provide minimum of 5mm coverage above the top of the heating element, prior to the vinyl floor finish being laid.

Tile/Stone – Fully encapsulate the Pinnacle Mat within either a flexible smoothing compound or flexible tile adhesive, prior to the tile / floor finish being laid. Pinnacle recommends the use of a plastic trowel when laying tile adhesive, to protect the underfloor heating cable from accidental damage.

Carpet – Fully encapsulate the Pinnacle Mat within a 10mm bed of flexible smoothing compound, to provide a minimum of 5mm above the top of the heating element., prior to the carpet floor finish being laid. Avoid rubber or foam backed carpets. Please check with the carpet manufacturer to ensure the carpet is suitable for underfloor heating.

Timber – Fully encapsulate the Pinnacle Mat within a nominal 10mm bed of flexible smoothing compound layer, prior to the timber floor finish being laid. When installing natural wood floors it is recommended that soft wood floors should not exceed 20mm in thickness, hard wood floors should not exceed 30mm in thickness.
