Western Red Cedar Cladding PEFC

Western Red Cedar cladding profiles & sizes

We stock Western Red Cedar cladding in the most popular profiles, shiplap, tongue & groove and channel, across a range of board widths and thicknesses. Cedar is also sold as cedar siding, the American term for the same cladding boards for bespoke projects. Browse the options above for live pricing and sizes per board.

How Western Red Cedar weathers the colour over time

Left untreated and exposed to the weather, Western Red Cedar's natural colour changes from its rich honey-brown and reddish tones to an elegant silver-grey, usually within the first year or two. This silvering is purely cosmetic, it doesn't affect the timber's durability at all. Many people choose cedar precisely for that natural silvered finish.

If you'd rather keep the original honey colour, apply a UV-protection oil such as Osmo 420 UV-Protection Oil on installation and re-coat every few years; the UV filter slows the greying and holds the tone. Either way, cedar needs no preservative treatment to last, the choice is purely about the look you want.

Western Red Cedar cladding cost per m²

Western Red Cedar is a premium cladding timber, and pricing depends on the profile, grade and board size — as a guide, our cedar cladding starts from around £X per m². Because we supply direct rather than through a merchant chain, prices are competitive for the quality. See the boards above for exact per-board and per-m² pricing. If you're working to a tighter budget, Larch cladding gives a similar natural, silvering look for less.

Vertical vs horizontal cedar cladding

Western Red Cedar can be fixed vertically or horizontally, and the choice changes both the look and the battening behind. Horizontal cladding is the traditional approach and fixes to vertical battens. Vertical cedar cladding, increasingly popular on contemporary builds, needs horizontal battens with counter-battens behind, so water can still drain and air can circulate. Whichever way you run the boards, leave a ventilation gap behind and fix with stainless steel (see below).

Cedar cladding for garden rooms

Western Red Cedar is one of the most popular claddings for garden rooms, offices and outbuildings, it's light (kind to a timber-frame structure), naturally durable without chemical treatment, and gives a high-end finish. If you're weighing up the cheapest cladding for a garden room, honest options are Larch or thermally modified pine, which clad a garden room for less and still weather attractively; cedar sits above them as the premium choice where looks and longevity matter most. We supply all three, see Larch and Thermowood alongside the cedar above.

Fixing Western Red Cedar

Always fix cedar with stainless steel. Cedar's natural oils (tannins) react with ordinary or galvanised steel, corroding the fixing and causing black streaks down the cladding. Stainless steel A2 or A4 cladding nails or facade screws avoid this completely, we supply matched stainless fixings for every cedar board we sell. Leave a ventilation gap behind the boards on battens so the timber can dry, and the cladding will last for decades.
