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.
The key to any piece of wood is its moisture content. So, IF THE WOOD IS 7% MC (= to 38% relative humidity), it doesn't matter if it was kiln dried (properly) or air dried. If you air dry, however, the average outside humidity is 65% RH in almost the entire U.S., summer and winter.This is 12% MC.hy kiln-dried lumber is the best option for wood that will eventually 'live' indoors. 1998. by Professor Gene Wengert Q. Some one told me that kiln dried lumber is better to use than air dried.
