Why Thermo-Treated?
 

The changes in the wood become irreversible and are a lifetime.  During the thermo-treatment process, we change wood on a molecular level to make it durable and dimensionally stable. More specifically, the treatment burns poly-sugars and makes wood water repellent on a molecular level which prevents the wood from rotting or decaying and makes it identical to 350-year-old lumber (see the microscope view of wood before and after thermo-treatment).  Thermo-treated wood becomes naturally durable and stable for at least 25 years. Also, the process substantially reduces moisture-related shrinking and swelling because wood repels moisture on a molecular level.  The process is absolutely "Green" with no chemicals added.  As a result, thermo-treated products are 100% “Green”.
