Choosing cedar or larch cladding is rarely a question of one timber being universally better. The useful comparison is between the precise products offered: their species and origin, grade, profile, finished dimensions, appearance, finish and supply scope. Cedar can suit a refined architectural elevation or a more characterful British-grown brief, while larch is often selected for its pronounced grain and confident natural variation. This guide explains the differences that matter when shortlisting either timber for a home, extension, garden building or commercial façade in the UK.
Cedar or larch cladding: the short answer
Choose by the appearance and specification your building needs rather than by species name alone. Canadian Western Red Cedar is commonly associated with fine grain, broad colour variation and comparatively low weight. UK-grown cedar usually has a livelier, more knotty character. UK larch tends to show stronger grain, knots and natural colour variation, while imported larch products may be selected for a tighter or more consistent face depending on source and grade.
Those descriptions are a starting point, not a substitute for an actual sample. Grade, growth conditions, machining and board selection can make two products from the same broad species group look very different. Ask to see several representative boards or a joined sample panel in the proposed profile and finish before making a visual decision.
For a tailored comparison, define the project first: elevation area, location, building type, desired board direction, profile, colour expectations, maintenance approach and delivery programme. A quote based on that brief is more useful than a generic answer to which timber is best.
- Choose Canadian cedar for a refined, colour-rich face where the offered grade supports it
- Consider UK cedar when local provenance and a more characterful appearance suit the design
- Consider larch where pronounced grain and a robust visual character are welcome
- Compare exact grades, profiles and installed cover before comparing prices
What products are being compared?
Cedar cladding is not one uniform product. Canadian Western Red Cedar and UK-grown Western Red Cedar can differ in colour, knot content, available lengths, grading and general appearance. A quotation should identify the origin and grade rather than simply saying cedar. It should also state whether boards are supplied sawn, planed, textured, profiled, coated or otherwise processed.
Larch also covers more than one supply option. UK larch is valued for home-grown provenance and a distinctive, knotty face. Imported larch can have a different grain and grading profile. Product availability and sourcing change over time, so the supplier should confirm the exact material currently offered instead of relying on a broad trade label.
The comparison should therefore name the actual alternatives, for example Canadian Western Red Cedar shadow-gap against UK larch shadow-gap in equivalent finished sizes. Without that detail, differences in grade, cover width or machining can be mistaken for differences caused by the timber itself.
Appearance, grain and grading
Cedar is often shortlisted for contemporary homes and carefully detailed commercial work because selected grades can provide a fine, relatively calm grain. Its natural colour can range across warm brown, red and honey tones, sometimes within the same elevation. UK cedar generally introduces more knots and movement in the grain, which may be exactly right for rural, residential or community projects seeking visible character.
Larch usually has a more assertive grain pattern. UK larch can include cream, pink and brown tones with noticeable knots, giving barns, extensions, garden buildings and larger areas a strong natural rhythm. Imported larch may present differently according to its origin and grade, so it should not be judged from an image of another supplier's product.
Write the accepted face quality into the brief. Confirm which face will be visible, what natural features the grade permits and whether appearance selection is included. Digital photographs are helpful, but a physical sample is better for judging colour, surface texture, joint shadow and how several boards work together.
Stability, board dimensions and machining
Canadian Western Red Cedar is widely chosen where low weight and dimensional stability are useful attributes, but the finished result still depends on board section, moisture condition, profile, support and installation. Larch is typically denser and can produce a crisp, substantial-looking board, although density and machining quality vary between products and batches.
Do not compare nominal sizes alone. Ask for finished thickness, overall width, installed cover, profile drawing and intended orientation. A board with a lower linear-metre price may cover less wall once the joint is engaged, while a different thickness or length mix can change both appearance and quantity.
Long runs, narrow boards, deep profiles and exposed elevations all deserve project-specific review. The designer, installer and supplier should align on support centres, board layout, movement allowance and fixing zones. Species choice cannot compensate for a profile or installation detail that is unsuitable for the actual wall.
How cedar and larch weather outdoors
Uncoated cedar and larch both change colour outdoors as sunlight, moisture and exposure affect the surface. They generally move towards grey rather than retaining their fresh-cut colour. The transition is not necessarily even: deep eaves, window reveals, adjacent planting, orientation and wind-driven rain can leave sheltered and exposed areas looking different for a period of time.
If an even silvered appearance is central to the design, discuss expectations with the supplier and coating specialist. A weathering treatment may help manage the early colour transition, but it should be assessed as a specific finish system with its own preparation and maintenance guidance. It should not be treated as a promise that every elevation will weather identically.
If the original warm tone matters, an appropriate pigmented finish is generally more realistic than a clear promise to keep timber looking new. Obtain written guidance for the exact timber, surface and product, including which faces are coated, how site cuts are handled and how future access for maintenance will be managed.
Profiles, orientation and architectural style
Both cedar and larch can be offered in horizontal or vertical profiles, subject to available board dimensions and machining. Shadow-gap and open-jointed arrangements create defined lines and suit contemporary architecture. Tongue-and-groove or shiplap can create a more closed face, while board-on-board and feather-edge profiles bring deeper relief or a more traditional character.
The same profile can look quite different in each timber. Cedar's finer grain and colour range can emphasise a clean joint pattern, while larch's stronger grain and knots can make the boards themselves more visually prominent. A sample panel showing the proposed joint, fixing position and surface finish is the safest way to compare the complete effect.
Orientation also changes the supporting build-up. Vertical boards need a batten arrangement that preserves drainage and ventilation, while horizontal or open-jointed profiles have their own junction requirements. The full wall, including membrane, cavity, battens, insect protection, openings and flashings, should be designed for the building rather than copied from a generic image.
Treatment, coatings and maintenance
Neither cedar nor larch should be described as maintenance-free. An unfinished elevation still benefits from inspection so that blocked cavities, damaged boards, loose fixings, persistent wetting and failing junctions can be identified. A coated elevation also needs inspection and eventual maintenance according to the finish manufacturer's guidance.
Preservative treatment, decorative coating and weathering treatment are separate decisions. Whether any is appropriate depends on the exact timber product, sapwood allowance, desired appearance and project specification. Confirm compatibility before ordering, particularly where factory coating, fire treatment or another specialist process is being considered.
Fixings must suit the timber, treatment, coating and exposure. Their material, head style, length, position and edge distance should follow the product and project guidance. Unsuitable metal choices can mark timber, while inconsistent fixing lines can distract from an otherwise carefully set-out façade.
How to compare cedar and larch cladding costs
There is no responsible universal price difference between cedar and larch because quotations depend on origin, grade, finished dimensions, profile, surface, coating, board lengths, quantity and delivery. Availability also changes. A comparison based on an old online square-metre figure may not describe either product being offered for the current project.
Ask each quotation to state the installed cover and total area covered, not only the price per linear metre or board. Check whether machining, treatment, coating, corners, trims, fixings, sample approval, delivery and unloading are included. Length schedules and appearance selection can also affect material use and supply scope.
Value should be judged against the design brief. Paying for a cleaner grade may be worthwhile on a closely viewed entrance, but unnecessary on a characterful outbuilding. Equally, selecting a board only because its unit price is lower can be false economy if the installed cover, waste or finishing requirements differ.
Choosing for South West homes and commercial projects
A Bristol extension, a Somerset barn conversion and a coastal project in Devon or Cornwall can expose cladding to different combinations of shade, rain, wind and salt-laden air. Share the postcode, building height, orientation and surrounding conditions when seeking advice. These details help the supplier discuss finish, fixings, board lengths and delivery rather than making assumptions from the county alone.
Domestic projects often place strong emphasis on appearance, sample approval and how timber meets windows, roofs and landscaped areas. Commercial projects may additionally need repeatable batches, documented product information, delivery phasing and coordination with a wider façade specification. The appointed design team should confirm fire, moisture, structural and regulatory requirements for the complete wall system.
Cedar and larch can both be credible options across these project types when the selected product and complete design are suitable. The better choice is the one that meets the actual visual brief, documentation needs, build-up and maintenance plan—not the species with the simplest marketing claim.
What to send for a useful cedar or larch quote
Provide elevation drawings or measured wall areas, the project postcode, building type, preferred orientation and any profile reference. Add photographs or inspiration images, but explain which qualities matter: clean grain, visible knots, warm colour, a weathered finish, local provenance or a particular joint rhythm.
State whether the quote should include factory finishing, treatment, trims, fixings, samples and delivery. If the project is at an early stage, say which decisions remain open. This allows Canadian cedar, UK cedar, UK larch and other relevant products to be compared on an equivalent scope rather than forcing a premature choice.
