Western red cedar holds a specific place in building: a softwood that resists decay outdoors, stays dimensionally stable through weather, and takes a finish better than most of its competitors. In 2018 the species hit one of its most turbulent years in recent memory, with tariff-inflated prices, distributor consolidation, and just-in-time inventory squeezing the supply chain at once. The market shocks did not change the material’s core case. They changed how the industry sells it.
Contractors weighing cladding and decking options need the full picture before they specify. The rundown on material properties, installation methods, and finishing best practices for western red cedar in residential exteriors covers grade selection, fasteners, and coating schedules in one place. What follows here looks at the same material from the market side: why demand shifts, how promotion responds, and what that means on the job site.
Why Western Red Cedar Earns Its Place on the Job Site
Western red cedar (Thuja plicata) grows along the Pacific coast of North America, and the wood it produces pairs traits few other softwoods match. It is light, easy to cut, and stable enough to hold its shape through the wet-dry cycles that warp other species. Natural extractives called thujaplicins give the heartwood a resistance to fungal decay that most building woods lack.
Those qualities explain why the species shows up in log home construction, where walls carry weather and structure at once and a wood that resists moisture and insects is worth the freight. The same stability carries over to siding, decking, fascia, trim, and ceilings.
Physical Properties That Matter on the Job Site
Three numbers summarize why cedar behaves differently. Density runs roughly 21 to 23 pounds per cubic foot at 12 percent moisture content, which makes it one of the lightest structural softwoods in North America. Tangential shrinkage is about 1.9 percent from green to kiln-dried, roughly half the movement of many pines, so boards stay flatter after installation. Insulation value runs about 1.4 R-value per inch, higher than most framing lumber and enough to matter in uninsulated assemblies.
How the Species Compares to Other Softwoods
A comparison table keeps the numbers straight.
| Property | Typical Value | Why It Matters |
|---|---|---|
| Oven-dry density | 21–23 lb/ft3 | Light to handle, easy to cut and fasten |
| Decay resistance | Class B heartwood per ASTM D2017 | Handles exterior exposure without treatment |
| Tangential shrinkage | About 1.9% green to dry | Low movement means fewer warped boards |
| R-value per inch | About 1.4 | Adds insulation in siding and ceiling assemblies |
| Finish retention | 2–3x longer than most softwoods | Fewer refinishing cycles over service life |
The Competitive Threat from Composite Substitutes
The biggest shift in cedar markets has not come from weather or tariffs but from substitutes. Composite products gained ground through the 2010s on three fronts: improved performance, closer price parity with solid wood, and advertising budgets that cedar producers could not match on their own. Growth came partly from real product gains and partly from a misperception that recycled-content materials are automatically the greener choice and need little or no maintenance.
That dynamic is why the industry tracks how next-gen builders embrace western red cedar in their projects. A younger generation of contractors who grew up with composites is relearning what solid wood does well, and producers have started meeting them with data rather than nostalgia.
Where Composites Gained Ground
Composites made their biggest inroads in decking and railing, where decades of maintenance complaints about older wood products created an opening. Fiber-plastic boards offered consistent color, no splinters, and long warranties. The trade-offs showed up in price per square foot, heat retention in direct sun, and the difficulty of repairing damage in place.
Closing the Gap on Price
Cedar responded on cost. Pre-primed and factory-finished boards shortened installation time, and grade simplification let retailers stock fewer SKUs while covering the same applications. By the end of the decade the installed-cost gap between premium composites and clear cedar had narrowed enough that the substitute no longer won on price alone.
Multi-Platform Promotion in the Building Products Industry
Selling a natural material against well-funded substitutes takes more than price sheets. The Western Red Cedar Lumber Association runs a multi-platform program that includes print and television advertising, online content, product placement, architect outreach, and social media, with the fastest growth coming from the social channels. Each platform carries a different message because the audience differs.
The same structure shows up across the industry: a detailed analysis of 7 marketing strategies to promote your construction business breaks down how associations, manufacturers, and dealers decide where each message runs. The principle holds whether the product is a lumber species or a service.
Product Placement and Editorial Integration
One of the association’s most effective plays was a partnership with This Old House. Western red cedar was specified in high-value applications in the 2018 Idea House in Narragansett, Rhode Island. In exchange for materials, the program earned a 17-page magazine feature in the November 2018 issue, exposure to 3.5 million monthly followers on the show’s social channels, online coverage, and placement in the spring 2019 national television episode.
Continuing Education as a Sales Channel
Architects specify materials years before they reach a job site, so the association targeted the design community with Continuing Education Unit courses, learning sessions, and direct outreach. The payoff appeared in the 7,210-seat CHS Field in St. Paul, Minnesota, where the ballpark’s exterior cladding went to western red cedar after designers spent time with the program.
Durability and Service Life: What the Track Record Shows
Cedar’s sales case rests on longevity. Properly detailed and maintained, western red cedar siding and decking commonly deliver 40 to 60 years of service, and the decay-resistant heartwood keeps performing through rain, snow, and coastal salt. That life cycle changes the economics: a 50-year cladding interval amortizes material cost over a far longer period than a 15-year substitute cycle.
The longest-lived structures share a common lesson: performance starts before the first board is cut. Studies of ancient buildings, from the geotechnical features of the bedrock at the Athens Acropolis to the drainage that keeps foundations dry, show that site preparation and detailing decide how long any material survives. Cedar rewards the same discipline on a modern house.
Detailing That Extends Service Life
Three details separate a 20-year cedar job from a 60-year one:
- Back-prime every board before installation so the concealed face resists moisture from the wall cavity.
- Leave an air space behind horizontal siding so the back of the board can dry.
- Use hot-dipped galvanized or stainless fasteners, because cedar’s extractives corrode ordinary steel.
What Maintenance Actually Looks Like
Maintenance is a water repellent or semi-transparent stain on a three- to five-year cycle, with cleaning between coats. Composite marketing often presents that schedule as a burden, but the refinishing cost is small against the cost of replacing a cladding system early.
Data-Driven Targeting in Building Material Sales
Promotion stopped being a spray-and-pray exercise. The association tracks social media and website data to identify households planning renovations or material purchases, then tailors content by platform: price concerns on one channel, natural-versus-composite comparisons on another, ease of installation on a third. The targeting produced measurable traffic: web visits from social channels grew 402 percent in 2018, delivering more than half a million site visits and nearly one million page views.
Traffic alone does not sell lumber, so the program tracks what happens after the visit. A high percentage of those visitors moved on to the retailer locator to find a member dealer, the step that actually connects marketing spend to board feet.
For a single contractor or dealer, the same discipline applies at smaller scale. Marketing strategies that promote a construction business rely on the same loop: define the audience, pick the channel, measure the response, and adjust the message.
Measuring What Moves Sales
The metrics that matter are the ones tied to a sale:
- Retailer locator sessions, not just page views
- Inquiries that name a specific product or grade
- Quote requests that mention the campaign
Turning Data Into Content
Each data point feeds the next campaign. If installation questions dominate, produce installation content. If price dominates, publish cost comparisons. That feedback loop is what lifted social traffic by a factor of five in a single year.
Codes, Installation, and Long-Term Performance
None of the marketing matters if the installation fails, and installation starts with the local code. Western red cedar siding, decking, and trim fall under the same code provisions as other combustible claddings, with requirements that vary by region for fire resistance, ventilation, and fastening.
The fastest way to confirm what applies locally is a code check on western building guidelines before the bid goes out. The check covers clearances, flashing details, and fastener schedules that differ between a dry interior climate and a wet coastal one.
A Field Checklist for Cedar Installation
- Store bundles off the ground under cover, stickered so air moves through the stack.
- Acclimate boards to the job site for at least 48 hours before cutting.
- Prime all six sides, including end grain, before installation.
- Fasten with approved stainless or hot-dipped galvanized hardware at twice spacing along edges.
- Caulk only where the specification requires it; cedar needs to breathe.
The Short Version for Specifiers
A durable, stable, naturally decay-resistant species with a documented 40-year service life is a defensible specification. The market turbulence of 2018 did not change that. It changed how the industry communicates it: with data, with education, and with placement in projects people actually see.
