California Redwood has a nostalgic appeal — it's been used for decking and outdoor structures for generations. But Redwood is a softwood with a Janka hardness of just 420 lbf, roughly 8x softer than Ipe. Today's commercially available Redwood is largely second-growth with lower density and durability than the old-growth timber that built its reputation. For long-term outdoor performance, Ipe is in an entirely different class.

Head-to-Head Comparison
| Category | Ipe (Brazilian Walnut) | Redwood (California Redwood / Sequoia sempervirens) |
|---|---|---|
| Janka Hardness | 3,680 lbf | 420 lbf |
| Density | 69 lbs/cu ft | 28 lbs/cu ft |
| Durability Class | Class 1 — Highest | Class 2–3 (heartwood); sapwood is not durable |
| Lifespan (Outdoor) | Up to 75+ years | 10–20 years (second-growth) |
| Fire Rating | Class A (ASTM E84) | Not Class A rated |
| Maintenance | Optional UV oil; minimal | Annual sealing/staining needed |
| Cost (Upfront) | Higher upfront | Moderate (heartwood grades are expensive) |
| Cost (Lifetime) | Lower total cost | Higher — multiple replacements |
| Climate Suitability | All climates | Best in dry/moderate climates; degrades faster in wet |
Strengths & Weaknesses
Why Ipe Wins
- Over 8x harder — vastly more resistant to dents, scratches, and wear
- Up to 75+ year lifespan vs Redwood's 10–20 years (second-growth)
- Class A fire-rated — Redwood is not
- Twice the density — superior structural strength and stability
- Thrives in wet, coastal, and harsh climates where Redwood degrades faster
- No annual sealing required — truly low maintenance
Where Redwood Falls Short
- ✕Very soft — dents and scratches easily from normal use
- ✕Second-growth Redwood has significantly less heartwood and durability than old-growth
- ✕Requires annual sealing and staining for outdoor longevity
- ✕Prone to checking, splitting, and cupping over time
- ✕Only heartwood has natural rot resistance — sapwood decays quickly
- ✕Not fire-rated and burns relatively easily
- ✕Supply is limited and quality grades can be expensive
Fair Credit to Redwood:
- •Beautiful natural reddish color
- •Lightweight and easy to work with
- •Some natural rot resistance in heartwood
- •Iconic American wood with broad recognition
The Real Value of Choosing Ipe
Increases Home Value
An Ipe deck is a premium feature that elevates your property's appeal and resale value to discerning buyers.
Attracts High-End Buyers
Luxury homebuyers recognize Ipe. It signals quality craftsmanship and long-term investment — making your home stand out.
Build Once, Enjoy Forever
With a lifespan of up to 75+ years, Ipe eliminates the cycle of tearing out and rebuilding every 10–20 years.
Less Construction Hassle
One installation. No repeated contractor visits, no permits for replacements, no weeks of your yard being a construction zone.
The Bottom Line: Ipe vs Redwood
Redwood's reputation was earned by old-growth timber that's largely no longer available. Today's second-growth Redwood is significantly less dense and durable, with a typical outdoor lifespan of 10–20 years. Ipe offers up to 75+ years of low-maintenance performance, extreme hardness, and proven durability in every climate. If you're building a deck you want to enjoy for the rest of your life, Ipe is the obvious choice.
People who can afford the best choose Ipe — because replacing a deck is expensive, disruptive, and entirely avoidable.
