See American Ash for a description of the wood species. Thermowood is a modification process with steam and high heat treatment. This process takes between 48 and 96 hours, taking into account some variables such as; timber species, width and initial moisture content. Thermowood process can be divided into 3 stages; high temperature drying, heat treatment and cooling. Most of the negatives of wood are minimized and have been abolished. As a result of the high temperature applied to the wood, the substances which shorten the lifecycle of any timber (glucose, citric acid, resin etc.) which exist at the inner part of the wood are resolved and crystallized. This process makes the physical properties of the timber better, improves the durability and provides an excellent colour. The reduced moisture content of the wood and relative humidity removed the Thermo-Ash, Thermo-Iroko and Thermo-Oak becomes very stable.
