The wood that is thoroughly dried will not rot.The main cause of wood rot is Water and Moisture.
Dry rot occurs when wood comes in constant contact with water or moisture. This exposure allows fungus to grow and to weaken the structure of the wood;left unchecked, the wood will begin to deteriorate.
Wood is a natural material just like any other wood product. Unless it is kept dry or if it is kept in ideal conditions and environment, it will rot. If the wood is protected from moisture, more than likely it will not rot at any great speed and can last for many years.
Wood no matter what chemicals have been put on it to make it last will naturally rot and eventually become dust. Chemicals that are put on wood are not designed to make the treated wood last forever but rather simply lengthen the time frame of the wood to stay in better shape.
No.
Unless kept dry and in the right environment, wood, being a natural material, eventually decays. How long it takes and how badly it rots depends on a lot of factors. The first factor is the type of wood, and most important, whether or how the wood is protected from moisture.
