Thermowood is a form of wood that has undergone thermal alteration. It transforms ordinary wood into this incredible substance-using just heat (varying from 190–212 degree centigrade) and steam. They are completely natural, with no artificial additions, and maintain the inherent qualities of wood. The proprietary manufacturing technique used by the thermowood pergola manufacturers in Dubai involves progressive heat alteration of wood, which results in permanent changes to the chemical and physical characteristics of the wood.
