Thermally treated hardwood is a natural eco-friendly heat process that enhances dimensional stability and the natural patina of Mother Nature’s beautiful creation. Thermally treated hardwood reacts less to external moisture levels, making it more stable than traditional hardwood products. Styles are produced by a unique thermal process to achieve rich color visuals. Because wood is a natural product and each plank will react differently to this process it results in color variation. This kind of variation helps display the true wood characteristics and is one of the most desired attributes in hardwood flooring. No two planks are the same.
