Western Red Cedar cladding is one of the most recognisable finishes in contemporary British architecture. Its warm colour variation, fine grain and natural durability allow it to soften modern buildings without making them feel rustic. However, the phrase ‘cedar cladding’ can describe several origins, grades and profiles. Understanding those differences helps you request a meaningful quote and avoid choosing on appearance alone.
What is Western Red Cedar cladding?
Western Red Cedar is a lightweight softwood valued for its stability and natural resistance to decay. It is commonly machined into external cladding boards for houses, extensions, garden rooms, schools, offices and leisure buildings. Canadian Western Red Cedar is particularly associated with clear grades, straight grain and a broad palette running from pale honey and salmon through to deep red-brown.
UK-grown Western Red Cedar comes from the same species but develops in different growing conditions. It usually has more visible knots and stronger character. This can make UK cedar a compelling choice where local provenance and a natural, less uniform elevation are more important than a near-clear architectural face.
Why is cedar so popular for external cladding?
The attraction begins with appearance, but performance is equally important. Western Red Cedar is dimensionally stable compared with many softwoods, meaning it is less inclined to distort dramatically as conditions change. Its low density makes boards easier to handle, and its natural durability allows suitable heartwood to be used externally without pressure-preservative treatment.
Cedar also machines cleanly into a wide range of profiles. It can form precise shadow gaps for contemporary façades, traditional feather-edge boards for rural properties, open rainscreen battens or understated tongue and groove surfaces. That versatility allows the same species to support very different architectural styles.
- Warm, naturally varied colour
- Good dimensional stability
- Lightweight and workable
- Naturally durable heartwood
- Available in contemporary and traditional profiles
Canadian cedar or UK cedar?
Canadian cedar is often selected when a project calls for a refined, relatively consistent face with fewer knots. It suits crisp new-build elevations and commercial schemes where the cladding must read as a controlled architectural material. The grade matters: clear and knotty products should not be treated as interchangeable simply because they share a species name.
UK cedar is usually more expressive. Knots and colour movement create texture at a distance and can complement barns, countryside homes, garden buildings and community projects. It may also appeal to clients looking to reduce transport distance. Neither option is automatically better; the right choice depends on desired character, available grade, exposure, budget and detailing.
What happens to cedar as it weathers?
Fresh Western Red Cedar is famous for its red, pink and brown tones. Outdoors, ultraviolet light and weather gradually change the surface. If left unfinished, the timber moves towards silver-grey. The transition is not always perfectly even: sheltered areas beneath eaves can retain colour longer, while exposed faces change faster. Elevation orientation, surrounding buildings and rain patterns all influence the result.
Some clients welcome the silver patina and specify the façade with natural weathering in mind. Others use a UV-resistant coating to retain more of the initial colour, or a pre-weathering treatment to encourage a consistent grey. Any finish brings a maintenance requirement, so the expected appearance in year five should be discussed as carefully as the appearance on installation day.
Choosing a cedar cladding profile
Profile choice changes the amount of shadow, the visible board width and the way water moves across the elevation. Narrow vertical shadow-gap boards can emphasise height and create a contemporary rhythm. Horizontal shiplap draws the eye across a building and offers a familiar overlapping form. Feather edge produces deeper natural shadows, while open rainscreen arrangements create a strongly linear façade with visible gaps.
Ask how the proposed profile is intended to be fixed, whether it is suitable for the selected orientation and what coverage each board provides. A nominal board width is not the same as the visible face, and this distinction affects quantities and pricing. Corners, openings, ventilation, insect mesh and junctions should also be part of the design rather than left until installation.
How much does cedar cladding cost?
Cedar cladding prices vary according to origin, grade, dimensions, profile, finish, quantity and available lengths. Clear Canadian material typically commands a premium over a more characterful knotty grade. A factory coating, fire treatment or bespoke profile will also affect the quote. Delivery to the project and wastage allowances matter, particularly where an elevation relies on specific lengths.
The useful comparison is therefore the installed specification, not the cheapest isolated board price. Provide approximate square meterage, elevation drawings, location, preferred orientation and the visual standard you expect. This gives a supplier enough context to recommend an appropriate grade and calculate realistic coverage.
Is Western Red Cedar right for your project?
Cedar is an excellent option when natural warmth, stability and a high-quality machined finish are priorities. It can work on a compact garden studio or across a substantial commercial façade. It may be less suitable where the budget cannot accommodate the required grade, where a completely uniform colour is expected without maintenance, or where project-specific compliance requirements point towards another system.
The best next step is to compare cedar with one or two credible alternatives, such as larch or Thermowood, using samples and project-specific prices. The Cladding Centre welcomes enquiries of every size and can help you assess Canadian and UK cedar cladding, suitable profiles and the practical route from initial idea to supply.
