Simply Perfecting what Nature Started.
The Superior Thermowood process dries or “ages” raw wood and produces a product with a controllable moisture content typically less than 10%*. Microscopic scans show that the wood’s cell structure is physically altered by the process, and the wood that’s “created” displays characteristics that are remarkable similar to samples that are hundreds of years old. A private study by Lakehead University (in April 2004) shows that the Superior Thermowood process substantially changes the physical properties of the wood with positive results for those seeking a product that is physically stable, resistant to cracking, rot and at the same time, better looking. Visible differences are a clear indication of the changes that have occurred below the wood surface.
The changes that take place within the wood when treated by the Superior Thermowood process are simply spectacular. While dramatic changes are visible on the surface, with both the color and the feel of the surface being aesthetically improved, the most important transformations are found throughout the body of the wood. The process involves the physical structure of the wood improving on what nature has provided. By activating the natural protective agents found within the wood, together with the reformation and realignment of cells, a more evenly distributed natural moisture barrier is formed. Further, and of equal importance, naturally occurring sugars are broken down and rendered unusable to rot fungi, providing chemical free rot resistance.
Treatment of both hardwoods and softwoods provide a range of positive aesthetic changes, including more pleasing colour and improved acoustic qualities. Wood species most commonly used for thermo treatment are: Ash, Birch, Cedar, Pine, Poplar and Spruce. Although once treated, most other species exhibit similar benefits from the process.
Superior Thermowood is a dream material for the architect, designer and builder. Superior Thermowood can be used from ceiling to floor, in door and window framing, tongue and groove paneling to parquet. In addition to increased durability, the product offers beautiful depth of color, detailed grain definition, and unique physical qualities to provide limitless creative possibilities.
Successful use of Thermowood on high profile projects such as; the McDonald’s head office building in Helsinki, Finland; and interior and exterior applications for the Finnish Embassy in Berlin, Germany, have been recognized by the international design community.
* Traditional kiln drying typically results in moisture contents of approximately 17% depending on the species.
