Both species resist rot and insects naturally and are common choices for outdoor and sauna builds in BC — but they differ enough in color, density, cost, and best use that picking the right one matters. Here's how to choose.
Western Red Cedar (WRC)
- Color: Warm reddish-brown heartwood with a pale sapwood streak; weathers to a silvery gray if left unfinished.
- Weight and workability: Lighter and softer, easy to cut, nail, and work with hand tools.
- Natural durability: Naturally rot- and insect-resistant thanks to its natural oils, without chemical treatment.
- Typical uses: Fencing, decking, siding, pergolas, and general outdoor structures where cost-effective natural durability and the classic cedar look matter most.
- Cost: Generally the more affordable of the two, and more widely available in a full range of dimensions.
Alaskan Yellow Cedar
Technically a cypress (Callitropsis nootkatensis), not a true cedar — but universally sold and used as one.
- Color: Pale yellow, uniform color with a smoother, tighter grain.
- Weight and density: Denser and harder than Western Red Cedar — more resistant to dents, dings, and wear.
- Natural durability: Excellent natural rot resistance, often regarded as even better suited than Western Red Cedar for high-moisture and high-wear exposure.
- Typical uses: Sauna interiors (mild scent and tight grain make it a favorite for hot, enclosed spaces), decking and posts in high-traffic areas, and builds where a lighter, more uniform color is wanted instead of cedar's reddish tone.
- Cost: Generally the pricier of the two, reflecting its density, durability, and more limited supply.
Quick pick
Choose Western Red Cedar for fencing, general decking, siding, and pergolas where you want cedar's warm color and value. Choose Alaskan Yellow Cedar for saunas, high-wear decking and posts, or anywhere you want a paler, more uniform look with extra durability.
