Does anyone know anything about thermal wood? I was told they can take spruce and basically heat it to alter the cell structure so bacteria can't grow and then it ages like cedar for a fraction of the price.
I just heard about this sounds a bit fishy, Anyone know about this?

I have heard about it. Has to be heated to about 500 F. Also steam is injected into the chamber to control the humidity at certain stages in the process. Then special cool down with humidity control. Not something easy to do unless you are set up for it. The price is about twice that of treated yellow pine.

Our Russian friend, Sergey, has offered information at this forum a couple times. His "English" is a little hard to follow but he is an expert on thermal wood.

Hello friends!
Dan, thanks for kmplement!
Thermo tree has excellent quality from rot ipleseni. Well behaved in the sauna door, kitchen fsad. Good Stracht domaiz thermo pine at sea.
I came from Ukraine. On the Black Sea to do this job.
Thermo pine diameter of 120 - 80 mm.

About temperatures. Operating temperature of Fahrenheit 300 - 375. 500 F is not applied.

Thanks Serg,
Where can I find this type of wood? it doesn't sound like something I can do myself and I haven't seen it at home depot. Although I'll try anything once.

Sergey,
One more question, why use thermal beech for kitchen cabinets, I can see for a sauna door or any outdoor exposure. I originally saw it on TV, spruce used for a fence.

Thanks

Night Raider, zdavstvuy!
I think that the thermal timber, the company sells.

Kitchen extreme room for wood, warm - humid - cold. Wood hygroscopic facade teryat their geometry. Thermo solves this problem. Resistance moisture 4.8% annual exploitation of timber. The color changes throughout the thickness, paints, pigments not. Photo color beech, oak, pine natural after thermal, varnish, wax, sealant, no. No insects, larvae, they are burned, there is no food for insects. Thermo timber behaves bravely in the open air. Requires protection from ultraviolet rays.

Sergey,

You are right about figured wood. I have bought "scrap" from pallet shops, dried and planed it and taken it back to show the guys what they were wasting. They called it 3D wood.

If you Google Finnish Thermowood Association you will get a understanding of the technology---I had these folk here in New Zealand last year.

Pan Pac Forest Products Ltd here in Napier (NZ) have installed a pilot plant for testing

I know in New Zealand a lot of pine. It requires protection from mold, insects. Chemical treatment of eclogite bad. The correct course of protection technology pines thermowood. With help thermowood New Zealand has a new, perfect product thermo pine. I have previously written that did samples from New Zealand pine. For quality termodereo must have a residual moisture content of 6% - 7%. Finnish technology has the function to carry out only the terms. Drying takes place in other cells, this leads to a very expensive product thermowood. So I taught her a vacuum drying chamber drying qualitatively Russian, African and American Forest and then taught her how to carry out the terms. Two technologies in one setting with a different load capacity of 4 m3 to 25 m3.

Serg: love this thread and really would like to know more, but for the life of me, I have no idea what you just said, or meant to say. Two terms? Help?

I try to say this again, with human assistance, not with messy auto translator. There is a lot of pine in New Zealand. This sort of pine is soft and porous, not like in Siberia. That made New Zealand pine easy meat for the bugs and fungi. To fight these chemicals must be applied, what make effects on health and ecology. Thermo treatment is the safe alternative, where the clean process based on high temperature in oxygen free environment. The wood gains some new features what means benefits. Wood change the color all dimension through, what provide advantage with white scratches compare to tint. The only coating with UV filter natural wax required. Wood sugars were decomposed, as well as molecular level transformation provides with water repellence, all these make wood not be recognized as a food by biological microorganisms. Average annum humidity of the wood is 4.8% what makes advantage for goods in areas like sea shores, SPA and sauna. Flooring with no splits, doors are swellproof, stairs don’t creak. Thermowood equipment is expensive. I produce small capacity 1.5-4m3 chambers for farmers, and industrial type of 25m3 lumber per load. Farmer be able to mill 2-3m3 and put lumber in my vacuum kiln. As soon as lumber has been dried he just turns it thermo treatment mode with no reload. I have combined two technologies in one unit.

Sergey: thanks so much for your explanation. I think I have it now. Sounds like the cost is still pretty high, though, unless the markets develop more for the products... guess I'll take the wait-and-see approach since there's a bunch of other equipment I need first (like a high end planer and maybe a molder-shaper for siding and flooring).

I was talking to a salesman the other day and noticed thermal wood on his business card. He said he didn't actually have it yet because the company who has promised to supply it has had trouble getting the system running properly. I guess it is still on a learning curve in the US.

Den hello!

The U.S. has a certificate. It may have a different need?
Since that time I made a new schedule for drying timber diameter of 90 - 170 mm. Drying from 56% to 6% moisture content = 96 hours + 24 hours thermo 347 F. The entire process took 120 hours. Quality watch. It is interesting to understand, to know your opinion?

Den Socling · « **Reply #17 on:** May 22, 2010, 10:47:02 am »

Sergey,

What does "quality watch" mean? Does it mean that you are checking those logs and the quality is good? Getting a log down to 6% in 4 days is remarkable in itself. Doing the entire process in 5 days is amazing. If the quality is good, you have a good idea. It sure saves a lot of handling. Combining vacuum drying with heat treating is what you are doing, right?

Dan,
Thanks for question! I´ve done such a cycle for second time. The quality is good, in terms of checks or splits. Now I´m going to build log house, bathhouse with sauna, arbor or pavilion and others. I publish some photos here in 10 days or so. Yes, I have succesfuly combined both in one unit - vacuum drying and thermotreatment. Everything performs quite well. For log drying I've implemented absolutely new method and drying schedule.

Hello friends!
I am a business trip in Ukraine. Makes the design wooden construction of cheap small diameter logs. Made a few samples for testing. Crimean Peninsula is washed by the Black Sea, many sandy beaches on which to build a metal and concrete is a big problem. Wooden houses a good alternative, lightweight, quick installation of conservation ecology. Thermo wood tolerates aggressive air moist sea.
