Underfloor Heating Guidelines By Installation Format
Loose lay flooring is suitable for use over underfloor heating systems, but these must be controlled to keep the interface between the subfloor surface and the backing at no more than 85°F (USA) / 27°C (Canada).
The system must be switched off 48 hours before, during, and for 48 hours after the installation, then temperature gradually increased by no more than 4°F (2°C) per day to desired warmth.
The room temperature must be between 65-85°F (18-27°C) prior to and during installation.
Electrical underfloor heating: please consult manufacturer to ensure their system is compatible with this flooring. Mesh / wire systems must be bedded into a base coat of appropriate primer & levelling compound to cover the wires or mesh by consulting your underlayment supplier.
Mesh / wire systems: must be installed according to manufacturer instructions, embedded into a base coat of appropriately reinforced smoothing in consultation with the selected underfloor heating manufacturer.
IMPORTANT: Care must be taken to avoid damage to the floor caused by localised hot spots. Particular consideration must be given in placing rugs and items of furniture which do not allow hot air circulation. No responsibility for damage to floor tiles / planks can be accepted under these circumstances.

Planks / tiles may be installed over underfloor heating systems, but these must be constructed so that the temperature at the adhesive interface does not exceed 85°F (27°C) ensuring the correct adhesive is used. The underfloor heating must be commissioned before installation commences. It should then be switched off 48 hours before, during, and 48 hours after installation. The temperature can then be gradually increased to 85°F (27°C) at no more than 4°F (2°C )per day to the desired temperature.
Electrical underfloor heating: please consult manufacturer to ensure their system is compatible with this flooring. Mesh / wire systems must be bedded into a base coat of appropriate primer & levelling compound to cover the wires or mesh by consulting your underlayment supplier.
The room temperature must be between 65‑85°F (18°C‑27°C) prior to and during installation, for both concrete and wood subfloors.
For underfloor heating pipes set into concrete, prime the surface before applying a compatible levelling compound as per the manufacturer’s instructions.
IMPORTANT: Care must be taken to avoid damage to the floor caused by localized “hot spots / thermal blocks”. Consideration must be given in placing rugs, and items of furniture which do not allow hot air circulation. No responsibility for damage to floor tiles can be accepted under these circumstances.

Underfloor Heating: It is possible to install this product over floors incorporating underfloor heating, but these must be controlled to keep the temperature at the interface between the backing and subfloor surface at no more than 85°F* or 27°C.
Electrical Underfloor Heating: Please consult manufacturer to ensure their system is compatible with this flooring. Mesh / wire systems must be bedded into a base coat of appropriate primer & levelling compound to cover the wires or mesh by consulting your underlayment supplier.
NOTE: Underfloor heating may affect moisture levels. Consult your supplier for details.
