As the atmosphere in the kiln is heated and dried, drying occurs faster on the outside, and the outer fibers will have a tendency to shrink. The interior core of the lumber will be at a moisture content of fsp and will prevent the exterior shell from shrinking as much as possible.
How much will kiln dried lumber shrink?
When you begin removing bound water and the m.c. drops below 25 %, the wood begins shrinking. This applies to all species of wood, not just cypress. Wood will shrink during drying until the wood reaches about 10 % to 12 %, which is our target for kiln drying Cypress.
Does lumber shrink as Dries?
Shrinking and swelling occur as the wood changes moisture content in response to daily as well as seasonal changes in the relative humidity of the atmosphere, i.e., when the air is humid, wood adsorbs moisture and swells; when the air is dry, wood loses moisture and shrinks.
