Teak vs. Thermally Treated Ash: Which Is the Best Wood for Outdoor Furniture?
Choosing the right wood species is one of the most important decisions when investing in outdoor furniture. Sun, rain, temperature fluctuations, and moisture can quickly degrade materials that are not naturally suited to outdoor use. While many wood species can be used outdoors, only a select few offer the durability, stability, and longevity required for furniture that will provide decades of enjoyment.
At Marco Bogazzi, we carefully select hardwoods that balance performance, sustainability, and aesthetics. Among the most popular options are African teak and thermally treated ash—two exceptional materials that offer outstanding outdoor durability.
What Makes a Wood Suitable for Outdoor Furniture?
Outdoor furniture must withstand conditions that indoor furniture never encounters. The best outdoor wood species share several important characteristics:
Resistance to moisture absorption
Dimensional stability during seasonal changes
Natural resistance to decay and insects
Strength and durability
Attractive appearance that ages gracefully
Wood species that lack these qualities often warp, crack, rot, or require extensive maintenance when exposed to the elements.
Burmese Teak: The Traditional Benchmark

For generations, Burmese teak has been considered the gold standard for outdoor furniture. Its high natural oil content and exceptional durability allow it to perform remarkably well in harsh outdoor environments.
Teak develops a beautiful silver-gray patina when left unfinished and has long been favored for yacht decks, outdoor furniture, and architectural applications.
However, genuine Burmese teak has become increasingly expensive and difficult to source responsibly. Environmental concerns, limited supply, and rising costs have encouraged furniture makers and consumers alike to seek high-performance alternatives.
African Teak: Beauty and Durability
African teak is an excellent hardwood for outdoor furniture applications. While not a true teak species, it offers many similar characteristics, including excellent durability, dimensional stability, and resistance to the elements.
Its rich color and attractive grain pattern make it particularly appealing for contemporary outdoor furniture designs. African teak performs exceptionally well outdoors and can provide many years of service when properly maintained.
For homeowners seeking the warmth and beauty of a tropical hardwood, African teak remains an outstanding choice.
Thermally Treated Ash: A Modern Alternative

One of the most exciting developments in outdoor furniture materials is thermally treated ash.
Thermal modification is a process in which hardwood is heated to high temperatures in a controlled environment. This process permanently alters the wood's cellular structure, reducing its ability to absorb moisture and dramatically improving its dimensional stability and resistance to decay.
The result is a material that performs exceptionally well outdoors while retaining the strength and beauty of solid hardwood.
Unlike many tropical hardwoods, thermally treated ash is sourced from domestic forests in North America. This provides several advantages:
Sustainable domestic sourcing
Reduced transportation impacts
Excellent dimensional stability
Improved resistance to moisture and decay
Beautiful natural appearance
Thermally treated ash has become increasingly popular among architects, designers, and furniture makers seeking a sustainable alternative to imported tropical hardwoods.
Comparing African Teak and Thermally Treated Ash
Both species are excellent choices for outdoor furniture, but each offers unique advantages.
African Teak
Rich tropical appearance
Excellent outdoor durability
Attractive grain patterns
Proven long-term performance
Thermally Treated Ash
Sustainably sourced domestic hardwood
Exceptional dimensional stability
Improved decay resistance through thermal modification
Modern environmental profile
Attractive contemporary appearance
In terms of outdoor performance, thermally treated ash approaches the durability of premium tropical hardwoods while offering significant sustainability advantages.
Which Wood Is Best?
The answer depends on your priorities.
If you are seeking the appearance and character of a traditional tropical hardwood, African teak is an outstanding option that performs beautifully outdoors.
If sustainability, domestic sourcing, and long-term dimensional stability are important considerations, thermally treated ash is one of the most compelling outdoor furniture materials available today.
For many contemporary outdoor furniture applications, thermally treated ash represents an ideal balance of performance, beauty, and environmental responsibility.
Final Thoughts
The best outdoor furniture is built from materials that are designed to withstand decades of exposure to the elements. Both African teak and thermally treated ash offer exceptional durability and beauty, making them excellent choices for outdoor living spaces.
At Marco Bogazzi, we believe thermally treated ash represents the future of premium outdoor furniture. Its combination of sustainable domestic sourcing, outstanding stability, and impressive outdoor performance makes it one of the most versatile and environmentally responsible hardwoods available today.
Whether you're furnishing a patio, garden, porch, or outdoor retreat, selecting a high-quality hardwood is one of the best investments you can make in the longevity and enjoyment of your furniture.
