10 hilariously insightful foreign words. Kiln dried lumber is lumber that has been heated in a kiln so that it has a low moisture content. When the drying process is complete, the lumber usually has a moisture content of between 6% and 8%, making it significantly dryer than green lumber or air dried lumber.n the case of kiln dried lumber, the wood is dried in giant kilns with carefully controlled temperature and humidity levels. The goal is to get the boards to dry quickly and evenly, and to prevent warping that could render the wood unusable.
Wood in âgreenâ condition must be kiln-dried in order to be used as construction grade lumber for building purposes, as an example. Lumber production is a complex process in which green timber is sawn, dried and processed.hen the relative humidity (RH) in the air rises, wood absorbs moisture from the air; when the RH falls, wood releases moisture into the air. This occurs naturally, and it occurs throughout a wood productâs life span even after it has been harvested and kiln-dried for human use.
