Thermally Modified Ash vs. Ipe: A Comprehensive Comparison
When considering high-performance outdoor wood, there are two options at the top of the list due to their durability and aesthetics; thermally modified ash and ipe. While both offer unique advantages, they cater to different needs and preferences. Here we’ll explore the benefits of thermally modified ash and compare it to ipe to help you make an informed decision for your next project.
Thermally Modified Ash – A Closer Look
Thermally modified ash undergoes a specialized heating process that alters its physical and chemical properties. The wood is heated to high temperatures in a controlled environment, resulting in several desirable traits:
Enhanced Durability: The thermal modification process reduces the wood’s moisture content and increases its resistance to decay, insects, and warping. This makes thermally modified ash an excellent choice for outdoor applications.
Stability: With reduced moisture content and absorption that standard wood, thermally modified ash is less likely to swell or shrink, warp or twist, maintaining its shape and appearance over time.
Enhanced Appearance: The process darkens the wood, giving it a rich, warm hue throughout the board that enhances its natural grain without the use of chemicals or stains.
Benefits of Thermally Modified Ash
Sustainability: Ash is a more abundant and fast-growing species compared to ipe. It is available in North America, where as ipe can only be found in tropical areas of the world, requiring import. By opting for thermally modified ash, you’re making a more sustainable choice that helps reduce pressure on endangered species and reducing the carbon footprint of your selection.
Cost-Effectiveness: Generally, thermally modified ash is more affordable than ipe. This can be a significant factor for larger projects where budget considerations come into play.
Ease of Workability: Ash is known for its workability; it cuts and shapes easily, making it ideal for DIY projects or custom builds.
Low Maintenance: While both woods require some maintenance, thermally modified ash generally requires less frequent sealing and finishing compared to ipe, which can save time and effort.
Non-Toxic: The thermal modification process is chemical-free, making it a safer choice for families and the environment.
Ipe – A Closer Look
Ipe, also known as Brazilian walnut, is a tropical hardwood renowned for its exceptional strength and beauty. It has been a popular choice for decking and outdoor furniture due to its impressive properties. However, it has recently been added to the CITES list of endangered species.
Benefits of Ipe
Exceptional Durability: Ipe is one of the hardest and densest woods available, boasting a lifespan of 25 years or more without treatment. Its natural oils provide significant resistance to moisture, insects, and rot.
Rich Aesthetic: Ipe has a beautiful dark brown color that can deepen over time. Its natural grain patterns add a touch of elegance to any outdoor space.
Fire Resistance: Ipe has a Class A fire rating, making it a safer choice in areas prone to wildfires or where fire safety is a concern.
Low Thermal Conductivity: Ipe remains cooler to the touch in direct sunlight compared to many other woods, making it a comfortable choice for decking.
Both thermally modified ash and ipe have their strengths and can suit different needs. If you’re looking for a sustainable, cost-effective option that’s easy to work with and maintains a natural look, thermally modified ash is an excellent choice. Ultimately, your choice will depend on your specific project requirements, budget, and personal preferences. Whichever wood you choose, both options can help you create beautiful, lasting outdoor spaces that you’ll enjoy for years to come.
