For those who dont know about this process google "heat treated wood cladding” and you can read about it. It involves heating to 180-200 C/350-400F or so. It causes a reduction in ductility, but apparently significantly enhances durability.<br>
One technique that is a bit less controlled is to flame treat the wood and char it. Some people like the look (e.g. architects) but it is a finicky process and often run off from rain results in significant staining.<br>
The controlled Scandinavian process of heat treating results in some excellent durable products, especially if it is painted right after (as a lot of this product apparently is). The common method is to heat in an inert gas atmosphere, but I have heard that hot oil is also used and has advantages<br>
It seems that it is quite durable, a natural pressure treatment.<br>
