Wood drying (also seasoning lumber or wood seasoning) reduces the moisture content of wood before its use. When the drying is done in a kiln , the product is known as kiln-dried timber or lumber , whereas air drying is the more traditional method.

Apart from structural wood preservation measures, there are a number of different chemical preservatives and processes (also known as timber treatment, lumber treatment or pressure treatment) that can extend the life of wood, timber, and their associated products, including engineered wood. These generally increase the durability and resistance ...
The NHLA has a long history of being involved in the national and international issues that affect the hardwood lumber industry. In 1976, the hardwood lumber industry was concerned with the long-standing practice of the footage as an allowance for shrinkage in lumber measured after kiln drying. This practice was challenged as being misleading ...
Edging will take the flitch and trim off all irregular edges leaving four-sided lumber. Trimming squares the ends at typical lumber lengths. Drying removes naturally occurring moisture from the lumber. This can be done with kilns or air-dried. Planing smooths the surface of the lumber leaving a uniform width and thickness.
In-kiln drying is usually monitored by some type of moisture meter. Moisture meters are used to measure the amount of water in the wood so that the woodworker can determine if it is suitable for the intended purpose. Building inspectors and many more, carpenters, hobbyists, and other woodworkers often are required to have moisture meters.
Fibre saturation point is a term used in wood mechanics and especially wood drying, to denote the point in the drying process at which only water bound in the cell walls remains - all other water, called free water, having been removed from the cell cavities.
Some species of wood are better assembled green because wood splits less when nailed green. Other species shrink excessively, leaving voids between the individual pieces when allowed to dry. Often wood to be used for fine products, such as furniture, is kiln dried to stabilize it and minimise the shrinkage of the finished product.
