How do you air dry timbers?

The most common method used to air-dry lumber is to lay narrow sticks perpendicular to the layers of lumber to create an air space between each layer so the moisture can escape. A good foundation is critical to successfully drying wood.

What is the air drying of lumber called?

What’s the difference between air-dried and kiln dried lumber?

With air-dried wood there are no internal tensions baked into the wood. The high temperature of the kiln kills some of the subtler colors of the wood grain. Kiln dried lumber needs to be kept in a fully climate-controlled environment once it comes out of the kiln, because it reabsorbs moisture from the air.

How do you dry wood without a kiln?

Without a kiln, you should try to achieve an air-dry moisture content of 15-20 percent. Further moisture reduction occurs when you move the boards indoors where they’ll eventually reach their equilibrium moisture content (EMC).
