Air dried (seasoned) timber is the right stuff for external joinery and furniture use.

Kiln dried timber, unless re-acclimatised* is a risk if you make furniture or joinery products for use outside.

Kilning is a process that reduces moisture to a level that makes timber appropriate and fit for use in interior spaces, centrally heated, air conditioned with low ambient moisture levels of 8-14%.

Air dried timber hasn’t been through this process. It’s moisture levels are in the 17-22% region and because it is generally stored outside in the open air it is always acclimatised to the current conditions.

Thus, dear woodworkers and woodbuyers, if the job is external air dried timber is the right stuff to ask for.
