Kiln-dried wood is wood that has been dried in an oven or kiln. The kiln drying process involves controlling the environment, such as temperature, humidity, and steam levels, to efficiently bring green lumber moisture levels down to a "workable" range. Kiln drying is a standard practice in wood production mills and serves to reduce moisture content levels that can cause problems such as warping, twisting, binding, buckling, and adhesive failures in finished products. Kiln-dried wood is carefully dried out over a period of time, and during that process, the moisture is pulled from the wood, making it more durable and stronger. The benefits of kiln-dried wood include resistance to fungal decay, killing insects, larvae, eggs, bugs, and mold, and minimizing defects. Kiln-dried lumber is often used to make furniture as it lasts longer and has relatively high strength.
