    2 Thermal conductivity

    A setup with superior thermal conductivity delivers a improved warmth output all round, which suggests it is extra value-helpful to run. ‘Typically, the denser and thinner the wooden boards are, the additional heat that will pass as a result of effortlessly,’ claims Kimberley Thompson, get in touch with centre manager at Flooring Superstore.

    When you are thinking of how productive underfloor heating is, it’s worthy of bearing in brain that as a purely natural insulator, wood will get extra time to heat up than a covering such as porcelain tiles when your UFH is switched on.

    3 Expansion and contraction

    Wood is a hygroscopic materials, which means it absorbs moisture from the surroundings all around it, foremost it to grow in excess of time. When it cools, the wood contracts. This is an important thought to bear in mind when you have underfloor heating, as drastic fluctuations in temperature could bring about your flooring surface to warp about time.

    ‘All wood flooring ought to have an growth hole of minimum 10mm all over the perimeter of the floor,’ suggests Peter Keane, director of The Pure Wooden Floor Firm. ‘This permits house for the wood flooring to expand and deal when there is a rise in humidity levels or when the heating is turned off.’

The heated wires are wrapped in foil, supplying excellent thermal conductivity into the timber floor higher than.’

    1 Engineered

    Designed to limit expansion and contraction, this remedy includes a area layer of real wooden, mounted atop cross-laid sheets of plywood. Thanks to its sturdy building, engineered wood is usually assumed of as staying the ideal timber flooring alternative to in shape around underfloor heating.

    The layered development implies that the surface area expands and contracts as a comprehensive ground fairly than personal boards.

    The best veneer of really hard or softwood timber differs in thickness, relying on the product or service you go for, but indicates the flooring is strong. Alternatives with a thicker surface area veneer offer you a lengthier provider existence.

    2 Hardwoods

    Sustainable, tough and very long-lasting, hardwoods like oak are highly sought-immediately after. Nonetheless, a lot of flooring suppliers suggest against pairing good boards with underfloor heating, as the planks do not offer you the very same dimensional steadiness as engineered products.

    ‘Solid hardwood flooring will specific considerably more motion in excess of an UFH method as opposed to an engineered design,’ says Greg Elliot, head of technical at Havwoods. ‘If you’re keen to accept this higher quantity of movement, there are reliable selections offered – but likely with an engineered floor is the most secure remedy.’

    3 Laminates

    Showcasing a durable fibreboard core topped with a photographic layer and a protective apparent complete, laminate boards mimic the glance of real wood. Hard-donning, budget-pleasant and quick to clean, laminate flooring is resistant to the temperature changes from UFH. Indicating it won’t warp or buckle at increased temperatures.

    Slimmer laminate boards (up to 18mm) offer you the greatest warmth transfer.
