Air-dried wood is pretty self-explanatory, it’s wood that has been left to dry in the air, as opposed to applying heat to dry it. It is the more traditional method of drying wood and gives the timber a little more flexibility.
Air-dried wood contains much less moisture than green wood, but a little bit more than the faster and more aggressive method of Kiln drying. It’s this latent moisture content that makes it a little easier to work with than the Kiln dried alternative. Air dried wood is a solid, stable medium for construction projects such as furniture, as it’s easy to work with and does not go through the kiln process, which can cause damage to the wood.
