Thermally
modified wood (TMW) is gaining traction in the U.S. as an intelligent new
building material. Kevin DeMars of Attica Millworks, Inc., one of only a few
U.S. TMW specialists, answers some questions on this ingenious product.
Q. What is thermally modified wood?
A. It’s
wood that undergoes a precise application of heat and steam that changes the
wood’s cellular structure. No chemicals are involved. Consequently, the wood
becomes more stable and durable. It won’t grow mold.

Q. Why was the technology developed?
A. The process has been in Europe since the Vikings but the 1990’s
launched its
development as a science-based commercial technology due to the sauna
industry. Saunas generate heat and humidity. These are disastrous when
combined with wood.

TMW
provides all of wood’s attractive qualities without the problems of rot and
buckling. The thermal process gives wood those coveted dark, rich tones ... naturally.
No chemical stains are needed.

Q. Where does the best TMW come from?
A. In the U.S. the best TMW comes from wood that’s grown and
processed domestically,
then shipped to Europe for the thermal modification. There are several
domestic manufacturers but they lack the European experience. This is critical
because if the process isn’t done correctly, you lose the benefits. However, the U.S. is learning quickly.

Q. What species can be thermally modified?
A. Any species! Actually, some take it better than others. We
prefer ash but have mastered others such as red oak, hickory, poplar, maple,
spruce, and pine.
Q. Since TMW looks and acts like tropical woods, is there a benefit
to TMW over exotics?
A. Definitely. Thermally modified ash will look and act like ebony,
ipe, or wenge. None
of these exotics are sustainably harvested, despite their marketing. Meanwhile,
the U.S. has the best forest management in the world.

Q. Why is TMW a smart building material?
A. Unlike other hardwoods, TMW will work anywhere – kitchens,
basements, decking,
bathrooms – even radiant heated floors. There is no twisting, cupping, or gapping. With over a billion dollars in moisture damage to wood each year, imagine the savings with TMW! Consumers enjoy a 15-25 percent savings over traditional hardwoods so now being responsible to the environment actually saves money.
