Floor Heating

Underfloor heating creates one of the most challenging environments in which to lay a wood floor. The wider the plank, the more the potential for expansion and contraction of the wood floor. Heating the floor can further increase plank movement.

Excessive plank movement can lead to twisting, cupping and warping. That’s why it's vital to only use perfectly engineered wide plank floors with underfloor heating.

The term 'stability' refers to how much wood will expand and contract with humidity fluctuations. Increased stability = reduced plank movement. So the aim is to install wood flooring of superior stability over the floor heating system.

Our suppliers are renowned for their technical supremacy in this area, and can offer a range of options to ensure peace of mind with underfloor heating, as follows:

ENGINEERED PLANK CONSTRUCTION

The term 'engineered' means a plank of 3 layers or multi-layer structure, similar to a plywood structure. This engineered plank structure is approximately 70% more stable than solid wood planks ('solid' meaning wood that is not made up of layers). This is why 80% of wood floors installed in Europe are now of engineered multi-layer or 3-ply construction. All of our wood brands come in an engineered plank construction.

ADMONTER ENGINEERED PLANK - PERFECTLY BALANCED

An evolution of the engineered plank structure is offered by Admonter; a 3-layer engineered plank consisting of upper and lower layers of the same thickness (other manufacturers use a much thinner layer of wood on the lower layer than on the upper layer). Admonter's plank construction with upper and lower layers of the same dimensions ensures exceptional balance and stability. The integrity of this symmetrical structure cannot be beaten and means an Admonter wide plank floor will not twist, cup or warp, even when used with floor heating.

THERMO-TREATMENT FOR EXTRA STABILITY

Admonter thermo-treated wood is an additional 50% more stable than non-thermo treated wood. A perfect choice for use with floor heating, humid climates or in bathrooms. Thermo-treating wood is a way of colouring the wood throughout the wear layer, using heat and time, without the use of chemicals or dyes. Because of its technical advantages, beautiful appearance and chemical-free process, thermo-treated oak, ash, beech, larch and acacia are becoming very popular. A great alternative to tropical woods.  Admonter are a leader in the use of thermo-heated wide plank floors. For more information on thermo-treated floors, click here.

TWO LAYERS OF HARDWOOD

For particularly challenging environments we can specify that the bottom layer is made from the same species as the top layer; compared to a standard engineered plank that has a thin bottom layer of birch or similar. This construction creates a perfectly symmetrical plank as the stability rating of the identical species used on these two layers is the same, ensuring the inherent forces of wood are tamed. This structure is optional in the Classic Hardwoods range.


*Note: Installation instructions and heating instructions must be followed. Floor surface temperature must never exceed 29 degrees celsius.
