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.
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.
