Thermowood ash patio floor decking

Thermowood ash patio floor decking


Thermowood is a thermal modified wood. This method was invented and made by the Finnish. With this simple technology, they extended the life span of the wood that contacts with soil. Thus, bugs and other insects did not go inside the wood since they could not find hemicellulose there.

The result is that wood allows less water entering the timber at the same humidity; therefore, the dimensional changes are minimized while the timber's is weathering resistance increases . This process is completely chemical free and environmentally friendly. The process is carried out on those timbers that have the best properties, such as the Finnish pine and spruce, beech, aspen, birch, alder and ash trees.
