We first started the thermal modification of wood in 2005. We acquired a lot of experience, as over the years tens of thousands square meters of thermoash were produced in our factory.


During these years we mastered the production technology, as to make sure that our ready product always meets the client’s needs and expectations.

The two thermal chambers we use for the production of thermoash, have the capacity to modify 12.000m2 of wood in a month.

Our tools are modern, equipped with many electronic sensors and fully computer operated. This ensures the color of thermoash is consistent, and the physical properties are repeatable.


The highest quality of our product is certified by Wood Technology Institute in Poznań.

Our Customers include individual clients mainly from Central Poland as well as national and foreign wholesale stores.
