WUW kiln operators run solar, electric, and hybrid kilns, and heat sterilize wood to 140 degrees and 8% moisture content. Kilns are independently owned and vary in capacity from small 500 board feet to 10,000 board feet kilns. Drying times vary by kiln type, by the wood species being dried, by the thickness of the boards, and can take up to three months.
These WUW processors can tell you where their lumber came from, sometimes down to the exact location of where the tree grew.
We encourage homeowners to have something made from their own tree when possible.
