About us
About Us
Manufacturing thermally modified wood in Lithuania.
We are an independent Lithuanian manufacturer specialising in thermally modified wood products. From our production facility, we supply terrace boards, facade cladding, and batten to clients across Lithuania, Poland, and Western Europe.
Every board goes through a controlled thermal modification process at 190–215°C. No chemicals — only heat and steam. The result is wood that’s dimensionally stable, moisture-resistant, and built to last decades.
We’re not just a supplier — we’re a manufacturer. We control quality from raw timber to finished product.
Our technology
How Thermal Modification Works
Wood is heated in a controlled environment using only steam and high temperature. The process permanently changes the cell structure.
215°C
Maximum Temperature
Wood is heated to between 190°C and 215°C depending on the desired durability class and end application.
72h
Process Duration
The complete thermal modification cycle takes approximately 48 hours from start to finish.
0
Chemicals Added
Only heat and steam. No preservatives, no toxic treatments, no chemical additives at any stage.
