Western Red Cedar Cladding: Naturally Durable External Timber
Why Choose Western Red Cedar for External Cladding?
Western red cedar cladding is valued for its natural durability, stability and light weight. The timber contains natural oils that make it inherently resistant to moisture, fungal decay and insect attack without the need for chemical preservative treatment. This makes it a popular choice for architects and self-builders who want a premium natural cladding material that performs well outdoors over the long term. Cedar is also one of the most dimensionally stable softwoods available, meaning it is less prone to warping, cupping and movement than many other species when used in external applications.
Finishing and Weathering Options for Cedar Cladding
Cedar cladding can be left completely untreated, finished with a clear UV-resistant oil, or stained to a chosen colour. Left unfinished, cedar weathers gradually to a uniform silver-grey over the first year or two of exposure. This natural weathering is a popular choice for contemporary buildings where a clean, aged timber look is desired. If the original warm reddish-brown colour is to be maintained, apply a quality exterior oil or stain shortly after installation and reapply as required. Both approaches are low maintenance compared to painted softwood, which requires regular repainting to keep it in good condition.
Cedar cladding boards can be fixed horizontally or vertically to a timber frame or counter-battens. Secret nailing through the tongue is the preferred fixing method for a clean finish with no visible fixings on the face. Use stainless steel or silicon bronze fixings, as standard galvanised nails can react with the tannins in cedar and cause staining on the board face. Leave a small gap at all cut ends to allow for movement and treat any cut ends before fixing. Fix to battens with a ventilated cavity behind the boards to allow air movement and extend the service life of the cladding.
