KD- Kiln Dried

Wood is dried in a kiln by the process of kiln drying. It is an artificial, yet highly efficient, method of drying out logs. With this method, wood is dried between four and seven days. Kiln drying removes the moisture in the wood, as opposed to seasoning, which occurs over the course of a year to three years, when the wood will naturally release its moisture.

While drying in the kiln, insects are also killed, and there is little storage space needed, unlike when you season wood. Kiln drying also allows you to bring down the moisture content of wood to a specific level. However, air-seasoned woods tend to be a little stronger than kiln-dried woods, and at the same time cost more.

A lot of furniture, cabinets, and flooring are made from kiln-dried lumber. Outdoor furniture, fences, and decks are often made from air-dried lumber. The pallet industry utilizes green lumber the most.
