Air dried and machined timber cladding is a sustainable, healthy, building material achieving a weatherproof building envelope to high tolerances. 

Air dried timber for exterior cladding has been dried carefully over time after sawing in the same manner and method as our furniture making and joinery wood.

Why Choose Air Dried Wood for Cladding

This is a stable, durable, highly machined product that produces crisp aesthetics for high value new-builds, restoration and renovations works. 

The process of air drying means that the timber is seasoned. In air drying it has given off a substantial amount of moisture resulting in a more stable, workable wood than timber that is fresh sawn.

It means it will have minimal shrinkage as  in drying it finds an ambient moisture content, it balances with it’s environment and the only movement is a natural movement that happens slowly across the seasons rather than anything very noticeable.

Air Dried Timber Cladding Grades

The grade of timber used for cladding is generally high. Partly because of the raised expectations for the appearance of smooth machined profiled cladding, but mainly because the spec (thickness x width) of the cutting requires fewer/smaller knots,  tighter/straighter grain and less sap than for thicker spec sections.

External timber cladding has a significant job to do, it is not weatherproof but is the weathering layer of the building, along with the roof covering, and as such the timber needs to be of sufficient quality and grade.

Our air dried cladding timber is the same timber that will be used for decking and joinery…  at the moment we machine all of our cladding to order… and, if it isn’t used before it is a few years air dried then, in time it will probably end up being kilned and will become furniture or flooring, or kitchens or another internal use for the high quality timber.

*We talk a lot about machining the timber cladding but it is possible to use the same air dried timber in it’s sawn profile for an alternative, more textured finish without the issues of shrinkage and movement – see our case study no 1 for an example of sawn air dried square edge boards use as vertical ‘board on board’ cladding.
