While no wood is entirely immune to movement, Tigerwood is exceptionally stable and highly resistant to warping, making it one of the most reliable choices for various applications.
Understanding Tigerwood's Exceptional Stability
Tigerwood, scientifically known as Goncalo Alves, is renowned for its remarkable density and often interlocking grain patterns, which significantly contribute to its inherent stability. Compared to many other wood species, Tigerwood is less prone to warping, cupping, or splitting. This natural resilience means it maintains its structural integrity over extended periods, making it a robust and reliable material.
Specifically for applications like decking, where exposure to elements can challenge lesser woods, Tigerwood's stability is a major advantage. This stability means it maintains its structural integrity over time, making it a reliable choice for decking. Homeowners and builders can have confidence in its longevity. You won't have to worry about your deck developing unsightly cracks or bends, which can happen with less stable woods. This characteristic ensures a beautiful and structurally sound surface for years.
Factors Contributing to Wood Movement (Even in Stable Woods)
Although Tigerwood is highly resistant, it's important to understand that all natural wood products can exhibit some degree of movement under certain conditions. This movement is primarily driven by changes in moisture content.
Key factors that can influence any wood's tendency to move include:
- Moisture Fluctuations: Rapid and extreme changes in ambient humidity or direct water exposure can cause wood to absorb or release moisture, leading to expansion or contraction.
- Improper Acclimatization: Not allowing the wood to properly adjust to the local environment's temperature and humidity before installation can lead to instability post-installation.
- Incorrect Installation: Insufficient spacing between boards or improper fastening methods can restrict natural movement and lead to issues like buckling or crowning.
- Lack of Maintenance: Failing to seal or protect the wood from moisture and UV radiation can degrade its surface and potentially lead to greater moisture absorption.

Maximizing Tigerwood's Longevity and Stability
To ensure your Tigerwood installation remains as stable and beautiful as possible, follow these practical steps:
- Acclimatize Properly: Before installation, allow the Tigerwood to sit in the installation environment (e.g., on the job site) for several days to a week. This enables the wood to reach equilibrium with local humidity levels.
- Ensure Proper Installation: Always adhere to manufacturer guidelines for fastening, spacing, and subfloor preparation. Adequate expansion gaps between boards are crucial for accommodating minor natural movement.
- Apply a Quality Sealer: A good quality, penetrating oil-based sealer or deck stain will help protect Tigerwood from moisture absorption and UV damage, further enhancing its stability and appearance.
- Maintain Good Drainage and Ventilation: Especially for outdoor applications like decking, ensure proper drainage around and underneath the structure to prevent water accumulation, which can lead to moisture-related issues.
Tigerwood vs. Other Woods: A Quick Stability Comparison
The following table provides a general comparison of Tigerwood's stability against other common decking or flooring woods.
| Wood Type | General Stability | Prone to Warping/Cupping? | Best Use Cases |
|---|---|---|---|
| Tigerwood | Exceptional; highly resistant to movement. | Very Low | Decking, flooring, outdoor furniture |
| Ipe/Cumaru | Excellent; very stable and durable. | Low | Decking, boardwalks, heavy construction |
| Redwood/Cedar | Good; naturally resistant to rot and insects, but can be softer and more prone to dents. | Moderate | Decking, siding, outdoor furniture |
| Pine/Fir | Moderate; more prone to movement and denting without proper treatment and care. | High | Construction lumber, budget decking/fencing |
| Oak (Red/White) | Good; dense and strong, but can be prone to seasonal movement indoors if not acclimated. | Moderate | Flooring, furniture, cabinetry |
