Redwood Cedar: The Ultimate Guide to Redwood Cedar Timber, Craft and Outdoor Living
When choosing timber for a project, the phrase Redwood Cedar often appears on product labels, shop displays and in conversation with builders and garden designers. The combination isn’t simply marketing; it reflects a practical blend of properties found in timber marketed as redwood cedar, as well as the distinct characteristics of true Redwood and true Cedar species. This guide unpacks what Redwood Cedar means in today’s market, how it behaves in the British climate and how you can select, finish, maintain and install it for long-lasting results.
What is Redwood Cedar? Understanding the Terminology
Redwood Cedar is a term you’ll encounter in wood merchants, trade literature and home improvement outlets. In some contexts, it refers to timber sourced from redwood species (primarily Sequoia sempervirens, the coastal redwood) that is marketed for exterior use, and in others, to timber products that blend marketing appeal with the appearance and durability of Cedar woods such as Western Red Cedar (Thuja plicata). In the UK, the name often signals timber that offers warmth of colour, natural rot resistance and a workability that suits outdoor cladding, decking and fencing.
For clarity, it helps to distinguish three concepts often conflated by retailers and DIY enthusiasts:
- Redwood timber: Timber derived from the redwood species (not native to the UK but imported). It is prized for its strength, natural durability and striking muted red hues as it weathers.
- Cedar timber: Timber from true Cedar species, especially Western Red Cedar, renowned for its rot resistance, light weight and aromatic properties.
- Redwood Cedar as a marketed category: A label used to denote products that aim to combine the warmth and grain of Redwood with the durability and stability associated with Cedar, or simply to evoke those desirable traits in exterior wood applications.
In practice, when you buy Redwood Cedar you’re buying timber selected for outdoor life: it tends to resist decay, accepts finishes well and remains usable after long exposure to damp British weather. Always check the specification from the supplier about species, treatment and moisture content, because the exact performance depends on the underlying wood type and the protective treatments applied.
Redwood Cedar vs. Cedar Redwood: A Quick Comparison
Understanding the differences between Redwood Cedar and cedar-redwood blends helps prevent misaligned expectations. Here are the essential contrasts you’re likely to encounter:
Botanical Background
Real Cedar timber, such as Western Red Cedar, is derived from a coniferous tree native to the Pacific Northwest. It is naturally resistant to rot, stabilises well and takes finishes smoothly. Redwood timber, from Sequoia sempervirens, offers a distinct warmth and a different grain pattern. In practical terms, Redwood Cedar products mix these appealing characteristics, but the exact performance depends on the species mix and any post-harvest treatments applied.
Durability and Rot Resistance
Western Red Cedar is widely celebrated for its rot resistance and stability in damp climates. Redwood timber also possesses durability, but its resilience can vary with growth conditions, heartwood content and where the timber has been treated. When you see Redwood Cedar in catalogues or on a site, it will usually indicate a product designed to weather well and to be forgiving in fixings and finish maintenance.
Workability and Aesthetics
Both Cedar and Redwood are relatively easy to work with compared with many hardwoods. They plane cleanly, cut smoothly and nail or screw well, provided you use the correct fixings and pre-drill in some cases. Aesthetically, the natural tones range from warm, pinkish reds to deeper russets, with a pleasing grain that enhances exterior cladding and decking as it weathers to a soft silvery patina in some species.
The Aesthetic and Practical Properties of Redwood Cedar
Choosing Redwood Cedar for an outdoor project often comes down to how the timber looks, how it matures outdoors and how well it handles UK weather. Below are the key properties that influence performance and enjoyment of the finished result.
Colour, Grain and Scent
The initial colour of Redwood Cedar products tends to be a warm, reddish-brown with a subtle, even grain. Over time, exposure to sun and rain causes gentle weathering, developing a richer tone and a distinguished aged look. Cedar components, by contrast, are often lighter and more even in tone, though the exact colour can vary by species and treatment. The scent varies too; Cedar carries a characteristic resinous aroma that many find appealing, while Redwood can smell similar but with a different nuance depending on the specific wood type and any preservative treatment used.
Workability and Tooling
In workshop or on site, Redwood Cedar timbers typically cut cleanly with standard woodworking tools, though you should follow best practice: use sharp blades, pre-drill for nails or screws to minimise splitting and, when needed, clamp tightly to reduce movement during cutting. If you’re planning intricate joinery or large cladding panels, consider a powered planer and a router to achieve precise edges that maximise finishing quality. Both Redwood and Cedar respond well to sanding and sealing, which helps lock in colour and resist moisture ingress.
Maintenance is the practical route to longevity for any outdoor timber, and Redwood Cedar is no exception. The finish you choose will influence maintenance intervals, appearance and protection against the elements. Here’s how to approach finishes, maintenance cycles and protective treatments.
Staining, Oiling and Painting Options
For exterior use, many homeowners favour penetrating stains or oil finishes that highlight the timber’s natural character while offering protection against weather. Pedigree products from reputable brands can be used on Redwood Cedar to resist UV damage, water ingress and mould growth. If you prefer a painted finish, choose exterior-grade paints and primers designed for timber, and prepare the surface by removing mould and ensuring a clean, dry base. Remember that painting can obscure the natural grain, which for many is the main aesthetic appeal of Redwood Cedar. A semi-transparent stain is a popular compromise—it preserves the grain’s visibility while providing a durable protective layer.
Cleaning and Protection
Annual cleaning helps extend the life of Redwood Cedar. Use a soft brush and mild soap to remove dirt, then rinse with clean water. Avoid high-pressure washing, which can raise the grain and allow moisture to penetrate. After cleaning, reapply a protective finish if it’s showing wear. For decks, a maintenance schedule is particularly important; staining every two to four years is common, depending on exposure, foot traffic and the finish type. For vertical cladding, consider a light cleaning every two to three years with a refresh of sealant or stain as needed.
Treatments and Sustainability: Responsible Sourcing for Redwood Cedar
Environmental responsibility and durability often go hand in hand. When selecting Redwood Cedar timbers, consider how they’re treated and where they come from. A few practical pointers can help you make a well-informed choice that aligns with sustainable building goals.
Preservatives and Eco-friendly Options
For timber used outdoors, preservatives help resist fungal decay, mould and insect attack. Water-based, non-toxic finishes are increasingly popular for homes with families or pets, and many brands offer finishes with low VOCs. If you’re aiming for a low-maintenance approach, look for products that offer long-lasting protection and are compatible with the timber species you’re using. Always check the label for recoat intervals and any instructions about maintenance cycles to keep Redwood Cedar performing at its best.
Sourcing and Certifications
Where possible, opt for sustainably sourced Redwood Cedar where the supply chain is transparent. Certifications from recognised bodies, such as FSC or PEFC, provide reassurance that the timber was harvested responsibly and with adequate replanting. If you’re installing in a garden or a public space, this can be a meaningful part of your project’s environmental statement and may influence your warranty and insurance arrangements.
Applications: Redwood Cedar in the Home and Garden
Redwood Cedar is a versatile timber suited to many outdoor and indoor applications. From cladding that wraps a home in warmth to a deck or garden furniture that withstands the elements, the timber offers a reliable combination of beauty and practicality.
Exterior Cladding and Siding
Cladding made from Redwood Cedar brings natural warmth to a façade with performance that resists weathering when properly finished. The timber’s natural oils provide some protection, while the addition of a stain or sealant helps maintain colour and reduce moisture ingress. Cladding can be fixed vertically or horizontally, depending on design preference, and the wood’s natural grain often answers with a dynamic, living surface that ages gracefully in the British climate.
Decking and Fencing
Decking is a popular use for Redwood Cedar due to its good strength-to-weight ratio and resistance to warping when properly treated. Ensure suitable fixings, such as corrosion-resistant stainless steel or hot-dipped galvanised fittings, to prevent staining and structural issues. For fencing, Redwood Cedar offers privacy with a refined appearance and lower maintenance compared to some hardwoods. Regular cleaning and an annual protective coat help maintain the deck’s slip resistance and colour over time.
Garden Furniture and Structures
Garden arbours, pergolas, benches and planters made from Redwood Cedar capture the timber’s natural warmth, integration with garden surroundings and durability. When selecting furniture, consider thickness and joinery quality; deeper timbers and well-made mortise-and-tenon joints will endure more seasons of UK weather. Cedar equipment often includes an easy-care finish that minimises the need for frequent refinishing, making it a practical choice for busy households.
Buying Guide: How to Choose Redwood Cedar Timber
Choosing the right Redwood Cedar product involves balancing density, grade, moisture content and intended use. The following guidance helps you navigate typical purchases, from cladding to decking.
Grades, Moisture Content and Availability
Timber grades reflect the number and size of defects such as knots and splits. For external use, many builders prefer Select or Grade A panels or boards with a tight grain and minimal defects. Moisture content matters too; kiln-dried or dehumidified timber tends to stabilise faster and finish better. If you’re in the UK, verify that the timber has been dried to a low moisture content compatible with your project to minimise movement after installation.
Price Ranges and Value for Money
Redwood Cedar timber sits in a mid-to-high price range, reflecting its durability and aesthetic appeal. When evaluating price, consider long-term value: a product that retains colour and resists decay will typically lower maintenance costs over a longer lifespan. Compare similar finishes and ensure you’re not paying extra for marketing claims that don’t align with performance tests or supplier warranties.
Installation Tips for Redwood Cedar Projects
Proper installation is essential to realise the full benefits of Redwood Cedar. Below are practical tips to ensure a robust and attractive result.
Acclimation and Fixings
Allow timber to acclimatise to the project site for several days before installation. This helps reduce warping and movement after fitting. Use corrosion-resistant fixings compatible with timber and consider pre-drilling to prevent splitting in narrower boards. In UK conditions, consider a weatherproofing strategy that guards against seasonal damp and temperature swings, especially in exposed locations such as coastal areas or high wind zones.
Expansion Gaps and Drainage
Timber expands and contracts with changes in humidity and temperature. Leave adequate gaps between boards for drainage and expansion—this supports long-term structural integrity and keeps finishes intact. For decks, include proper drainage angles to avoid standing water, a common cause of staining and accelerated wear. For cladding, ensure the system allows air behind the boards to prevent moisture entrapment and the growth of mould or mildew.
Common Questions about Redwood Cedar
