Why choose Thermory?
We come from a country where more than half the land is covered with forest. We value wood. We care for forests. We value a healthy living environment. Timber is a renewable natural resource and with its use as a construction material we desire to reduce our ecological footprint and contribute to a nature-friendly way of living.
Thermory thermowood is our signature product
Years of experience and modern cutting-edge technology allow us to bring out the best properties of wood. Thermally modified wood is entirely natural – its characteristics are enhanced using only heat and steam. This chemical-free process results in an environmentally friendly and aesthetically pleasing wood material that is significantly more durable and stable than conventional timber.
