Air-Dried Lumber Air-Dried Lumber
Air-dried lumber is any wood which has been dried from the green stage, or freshly sawn stage, and has been seasoned so that it will not warp or bend in its usage in construction.
The two most common methods of drying or seasoning wood are air-drying and kiln-drying. While kiln-drying uses heat and humidity to speed up the process of drying the lumber, air-dried lumber is created through a completely natural process, allowing the wood to cure on its own, gradually, in contact with air. Air-dried lumber therefore takes longer to cure, because of the slower process.
Green Wood and Kiln-Drying Verses Air-Dried Lumber
Many woodworkers prefer the result obtained with air-dried lumber to kiln-drying. They cite superiority in milling the wood, finishing it, in its final project appearance, and most importantly, in the durability of air-dried lumber over kiln-dried.
Green wood will shrink or warp over time, therefore is not desirable in most uses. For framing or rough construction, moisture content of fifteen percent is acceptable. For interior finished wood, the moisture content of your air-dried lumber should be ten percent, and for fine furniture, eight percent or less.
