You may have already seen the timber and logs for sale in http://www.kilnservices.co.uk. However, you don’t have any idea how they were able to create a completely smooth wood, since there are times when you get timber and log, there are cracks everywhere when you have them for a very long time. When your furniture made of wood tends to get cracks as the years pass by, it only tells you that whoever built the furniture failed to acquire logs or timbers that have been completely dried out through kiln drying. The slabs of wood, timber and logs that you see in the aforementioned site have all gone through the kiln drying process, which is to remove the moisture content that is still present in the wood. This is very important even if you are working with a dead tree.
Why it is important for woods to go through kiln drying
The timber coming from living and dead trees contains a huge amount of water. This is not visible to the eye at all. When wood is utilized for construction, the material releases or absorbs moisture until it has reached its equilibrium with the environment it is surrounded with. The process of equilibration results in uneven shrinkage of wood, thus causing damage to the wood if the process gets hurried or happens too rapidly. The equilibration process must be controlled for the purpose of preventing wood damage. There are 2 ways of controlling this process: kiln drying and air drying.
Kiln drying can also be equated to controlled air drying. Modern ways of creating the kiln drying process allow very tight air flow control, including control over humidity and temperature. This way, all the timber present within the area dries evenly and up to its precise content of moisture needed. Kiln drying is sometimes seen as a more uniform product and its problems are sometimes linked with air dried timber that has been poorly air dried is totally avoided. Timber that has gone through kiln drying can be manufactured to a highly superior finish compared to air dried timber. This way, problems like raised grain are eliminated. They can be installed with its minimal acclimitization on the site and is even suitable for immediately finishing with stain or paint. This means that the wood can be protected but must be done without delay.
What about air drying?
Air drying is literally drying wood naturally exposing it to the air. Timber and logs are stacked on boards and have spacing in between them. They are separated by sticks on foundations that are raised within a dry and cool place. The drying rate totally depends on the conditions of the climate including the exposure of the wood to the wind. In order to achieve success with air drying, a uniform and continuous flow throughout the whole stacks of wood must be arranged properly.
Oftentimes some households combine air drying and kiln drying because they believe it gives a more even result with the wood. Some of the timber and log available at http://www.kilnservices.co.uk are done this way as well.
