Flooring Useful Information

Thermo-Treated Ash

Thermory® only use high quality timber (both heartwood and sapwood) for their flooring boards, harvested from well-managed forests in North-America where good growing conditions and strict drying standards are maintained. This range has been subjected to their ‘intense’ thermo-treatment’, which heats and steams materials up to a maximum temperature of 215°C, ensuring maximum stability and a dark, rich colour throughout the timber. This chemical free process also ensures a low moisture content, removes resin, reduces splitting strength and improves durability against decay. The end result is the transformation of responsibly sourced ash into an extremely durable flooring board.
 

Colour Variation

As a natural wood product, thermo-treated flooring is subject to colour variation. This is due to variances in the shading of the raw timber and its density and composition, as this impacts on the degree of darkening brought about by thermo-treatment process. Colour variation can vary from board to board and even within the same piece. Please note, this is not considered a defect.
 

Acclimatisation

In addition to improving dimensional stability, thermo-treatment lowers the Equilibrium Moisture Content (EMC) of the timber. As such, thermo-treated flooring is far less liable to shrink and expand that its traditional counterparts. It should, however, still be acclimatised at room temperature for at least 7 days.
 

Finishing

Themory® Hardwood Flooring is supplied unoiled, allowing it to be finished on site to exact specifications. We recommend using 10% diluted Treatex Hard Wax oil for the first coat. The clear version improves surface durability whilst bringing out the timbers deep, rich colour tones and grain. It also inhibits short term fluctuation in moisture content. In high footfall areas, Treatex hardening additive should be added to the oil.
 

Sanding

Thermory® Flooring comes cleanly planed and pre sanded. Nevertheless, as this product has bevelled edges, contractors may find it necessary to apply a light sanding prior to the application of oil to even out any subtle height differences among planks. As the sanding dust is very fine, we recommend that installers use a high quality dust containment system throughout any sanding process and wear a dust mask. As with all wood floors, colour may change slightly over time as a result of oxidation and/or prolonged exposure to sunlight. This is not a defect, but a natural property of wood. Whilst some lightening is inevitable, it can be delayed through the application of oil. It can also a good idea to rotate rugs and furniture to ensure even exposure to light throughout the room. To restore the floor, sand off the finish to reveal its original colour.
