Air Dried Packs
Air dried oak is ideal for external joinery, as it has the right moisture content to keep its shape when exposed to the elements.
The moisture content is typically between 15 and 18%.
We only recommend air dried oak for external work, as kiln dried oak would be too dry.
Our air dried oak has been cut from waney stock after it has been drying for at least 1 year per 25mm of thickness. This results in boards which are at equilibrium moisture content for external use. They will not swell and leave you with windows that can’t be opened!
Having the time to air dry slowly also removes tension from the wood, so you can be confident that your 6m board will have no more than a few mm deflection in width.
