Lunawood Thermowood
LUNAWOOD THERMOWOOD is a beautiful, sustainable wood material produced by using natural methods, heat and steam. Thermal modification improves the wood’s properties, thereby expanding the range of applications in which the wood can be used. Thermowood is dimensionally stable, resistant to decay and resin free. It can be used inside or outdoors, in any climate. Lunawood is an non-toxic natural product which is easy to machine and install.
Dimensional Stability
Lowered equilibrium moisture content of Thermowood makes it dimensionally stable and the material retains its shape far better than untreated wood.

Process
Even the ancient Vikings knew that when building defensive fencing for fortifications, poles made from wood with a burnt surface were more durable than poles which had not been treated in any way. Studies on the possible benefits of thermal modification of wood began as early as the 1930s and 1940s in Europe and USA, but the manufacturing process never reached an industrial scale. Decades later, VTT (Technical Research Institute of Finland) became interested in the idea and as a result, the Thermowood process was patented and the brand was launched in Finland at the end of the 1990s.
The Lunawood thermal modification process uses only heat (ranging from 190-212°C) and steam. Lunawood end products are completely natural and free from chemical additives.
The Thermowood process respects the natural properties of wood. The patented production process is based on the gradual thermal modification of wood, wherein the chemical and physical properties of wood undergo permanent change. Thermowood is a registered trademark and may only be used by member companies of the International Thermowood Association. Lunawood is one of the association’s founding members. The quality of Thermowood production is monitored by an independent, external party.
The best raw materials
We use mainly Finnish PEFC-certified wood in our production that is sorted in accordance with our specific and strict requirements. The high and even quality of our production is based of a logistics chain that is carefully managed from forest to final product. Together with our suppliers, se select and use only the raw materials that are the best suited for our production in terms of type and quality.
Quality and environment
Lunawood Oy has and will continue to set quality requirements for Thermowood in order to take responsibility for the care of the environment. To ensure this, our quality chain goes all the way from the source of the raw materials to the end consumer. No chemicals are used in the manufacturing process of our products, which provides a good basis for the ecological soundness. Applied correctly, heat and steam are sufficient to turn wood into a durable and impressive construction material. At the end of its life span Thermowood, being a pure natural product, can be burned and turned into bio energy or recycled.
Environmental concerns are important to us, we are proud that our products are labeled with the Scandinavian eco label, the Nordic Swan. Lunawood is an ecological option for durable outdoor and environmental construction. It is free of heavy metals and pesticides and will not become hazardous waste at the end of its life span.
The quality chain starts in the forest. The chain-of-custody management of the raw material is certified, which means that it is assessed and monitored by an independent third party. As recognition of the company’s exemplary chain-of-custody management, Inspecta Oy has awarded Oy Lunawood Ltd a chain-of-custody certificate. Based on this certificate, the Finnish Forest Certification Council has awarded Oy Lunawood Ltd the right to use the PEFC certification label.
The International Thermowood Association supervises its member companies’ quality of production. This supervision is conducted by Finotrol Oy as an independent third party. Finotrol Oy awards a certificate to companies that meet the quality requirements, on which basis the International Thermowood Association awards companies the right to use the TMT certification label.
Durability is a part of quality. The international KOMO certificate, awarded and monitored by SKH in the Netherlands, is further proof of our expertise. The KOMO certificate confirms that Lunawood Thermo-D –class materials meet the quality requirements set for their biological durability and production.
All of our products are made in Finland. As a guarantee of their domestic origin, they have been granted the right to use the Finnish Key Flag emblem.
Lunawood exterior cladding products are also CE-marked, which guarantees their performance.
Oy Lunawood Ltd’s quality manual partly follows the ISO 9001 standard and is included in our quality control system.
