First, kiln drying produces logs that are more uniform and dimensionally stable.
Second, timbers are sanitized when they are heated to 170 degrees F, in a kiln. Such heat kills mold, wood decay fungi, and any insects, their eggs and larvae.
Third, pitch in the wood is crystallized by the heat of the kiln. This prevents the sticky substance from seeping through the logs.
Fourth, more than 10,000 pounds of water can be removed from a typical log home during the kiln-drying process. This significantly reduces weight for both shipping and handling on the worksite.
Finally, interior and exterior finishes can be applied immediately after construction and applications tend to penetrate deeper and last longer on kiln-dried logs.
