During the past 20 years, European companies have perfected the process of thermally-modifying softwoods to enhance their durability, longevity, dimensional stability and more. In 2004, the European Union banned chemical additives for wood protection, resulting in the need for eco-friendly wood treatments and a growth of 30% each year in the thermo-treatment lumber market.
Although European countries have exported these products into North America for many years, Rockwood™ is a domestic supplier of thermally-modified hardwoods, which allows for reduced shipping time and costs in relation to importing these products from overseas.
The Process of Thermally-Modifying Wood
The process of thermally-treating lumber includes gradually-heating wood up to temperatures of 410-450º F to create permanent reactions within the materials.
These changes include:
Creation of a rich, deep brown, color to the wood
Thermo-treated wood also weighs less, is dimensionally-stable, and will not split, rot or warp over the years. Because of this, we offer a 25-year warranty when the product is used outdoors.
Eco-Friendly Benefits of Thermo-Wood
Rockwood™ thermally-modified wood is eco-friendly. It is wood not treated with chemicals or plastics and serves as a viable alternative to imported tropical rainforest wood. So, while it’s similar to rainforest wood in look and quality, it doesn’t pose a threat to the rainforest ecosystem and eliminates the cost to buy rainforest wood and bring it to the United States.
The Rockwood™ Difference
At Rockwood™ thermally-modified hardwoods, we have partnered with two cooks/manufacturers for the products we offer.
One is a domestic manufacturer in Georgia who has been in business for 7 years and patented the process of thermally treating American Hardwoods to bake out the sugars and fibers that serve as a food source for fungus, mold, and decay (all deterioration factors for traditional lumber).
We also have an international manufacturer that supplies us with thermally-modified European Softwoods.
