Air dried timber cladding is a sustainable, healthy, building material. It achieves a weatherproof building envelope to high tolerances.

Our air dried timber has been dried carefully over time, after sawing in the same manner and method as our furniture-making and joinery wood. Once machined it is ideal for exterior timber cladding.

Why Choose Air Dried Timber for Cladding?

Air dried cladding is a stable, durable, highly machined product. It produces crisp aesthetics for high-value new builds, restoration and renovation 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.

Air dried timber has minimal shrinkage. In drying, it finds an atmospheric moisture content, it balances with its 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 external wood 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 timber cladding is the same timber that is used for decking and joinery. We currently machine all of our external wood cladding to order. If it isn’t used before it is a few years air dried then – in time – it will probably end up being kilned. The timber will be used for furniture, flooring, kitchens or other internal uses that require high-quality wood.

*We talk a lot about machining the timber cladding but it is possible to use the same air dried timber in its 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.
