Everything You Should Know About Kiln-Dried Wood

As soon as lumber has been harvested, it is green which means that is has not gone through any drying process. You can certainly expect green lumber to have a high moisture content and because of this it tends to contract and warp when it is dries. This is the reason why lumber that is being produced for commercial purposes will go through a kiln before selling it.

Kiln dried wood logs have gone through a process which was done in an environment where humidity levels and temperature are carefully monitored. It is really important to carefully monitor these factors to ensure that the wood is drying evenly and quickly which will prevent the wood from becoming warped. If it does then the wood becomes useless. The process of kiln drying the log continues until it reaches the optimal moisture content which is five to eight percent.

If you are going to buy kiln logs then you need to remember that this is not permanent. This is a common misconception among buyers. Do not forget that wood is naturally hygroscopic. This means that it has the capability to absorb the moisture that it comes into contact with. It can be the water from the rain, air humidy and even the moisture in the objects close by. And even woods that have been kiln-dried will not lose this capability. So you should never forget that the moment the kiln-dried wood will leave the premises of the lumber company where the environment is controlled to ensure it stays in its optimum state, then the moisture can change. It can change during the transportation of the wood, storing the wood in the shed or garage and even when manufacturing it.
