Kiln Dried Lumber

Kilin use for Kiln Dried Lumber

Kiln Dried Lumber Drying Process

After the logs are cut to lumber, they are stacked on “stickers” of 1-inch thick hardwood stacking sticks that create a space between each layer of wood for airflow. The lumber will need to sit in the shed with good airflow and minimal sunlight until it reaches under 30% moisture content. At that point, the wood can go into the kiln to speed up the final drying process and to get the lumber drier and hotter (bug kill) than it naturally would. Kiln Drying is done in a conventional dry kiln with heat and airflow controlling the humidity to follow a set schedule for the wood species and thickness. The vacuum kiln puts the wood under a vacuum to decrease the temperature; the wood needs to maintain a specific temperature to remove the water. This process creates suction, which pulls the core moisture out to the exterior of the wood. The lumber is dried on average to 7-5% moisture content for interior or furniture grade use.

Common Lumber Dimensions

  • 1 ⅛ inch thick boards from 4 inch – 12 inch wide and 8 ft-16 ft long
  • Same thing but 2 inch thick boards
  • 2 ½ inch slabs random widths and lengths
  • 5-8 inch thick mantel stock

Can I Bring My Own Wood?

Yes, we can dry the customers’ lumber, however it will need to be pre/air-dried to 30% or less moisture content to go into the kiln. We don’t have a lot of storage so it’s better if you can just bring it after it has been air drying. Depending on the species and thickness, this process can take 30 days to 2 years to fully air dry. Contact us for more information.

What Is The Average Drying Time in the Kiln?

Assuming the lumber is around 30% or lower the average drying times in the kiln should be 1-2 weeks for around 1 inch thick lumber, and 2-3 weeks for 2 inch thick lumber. Thicker lumber would be very custom and would need special attention since it needs to be dried much slower for thicker lumber like beams or mantels.
