Second Generation of ThermoWood

Thermally modified wood is produced on industrial level in Europe since the end of last century. Several processes are available, with the highest quantities following the Finnish Thermowood process. This project was performed in close cooperation to the ITWA (International Thermowood Association). The goal was to improve the quality of Thermowood with the main focus on end-products like decking, cladding and window joinery. Comprehensive studies on the influence of the raw material and the process steps on quality issues were researched. Understanding the chemical and the physical changes caused by process parameters were focussed on as well as surface related properties.
