Thermally Modified Ash vs. Thermally Modified Pine: A Comprehensive Comparison
When it comes to sustainable and high-performance wood products, thermally modified wood has emerged as a popular choice. Among the options available, thermally modified Ash and thermally modified Pine are two of the most favored species. Both types of wood undergo a heat treatment process that enhances their durability, stability, and resistance to decay, but they have distinct characteristics and applications. This blog post aims to compare and contrast thermally modified Ash and thermally modified Pine, helping you make an informed decision for your next project.
1. Appearance and Aesthetics
Thermally Modified Ash: Ash wood is renowned for its light color and pronounced grain pattern. The thermal modification process darkens Ash, giving it a rich, deep brown hue that accentuates its natural grain. This aesthetic quality makes thermally modified Ash a popular choice for applications where visual appeal is paramount, such as decking, siding, soffits, and outdoor furniture.
Thermally Modified Pine: Pine, in its natural state, is lighter in color with a more uniform grain pattern compared to Ash. When thermally modified, Pine takes on a golden-brown to chocolate-brown color. While its grain is less pronounced than Ash, thermally modified Pine offers a warm, rustic and refined appearance ideal for exterior cladding, decking outdoor furniture, fencing, soffits
2. Durability and Stability
Thermally Modified Ash: Ash is a hardwood, and when thermally modified, it becomes even more durable. The heat treatment process significantly reduces the wood's moisture content and removes organic compounds that can cause decay. This makes thermally modified Ash highly resistant to rot, insects, and weathering, making it suitable for both indoor and outdoor applications. Its enhanced dimensional stability also means it is less likely to warp or shrink with changes in humidity.
Thermally Modified Pine: Pine is a softwood, which generally means it is less dense and less durable than hardwoods like Ash. However, thermal modification drastically improves Pine's durability and stability. While not as hard as Ash, thermally modified Pine is still resistant to decay and pests, making it a viable option for exterior applications. It is also less prone to warping and shrinking compared to untreated Pine, though it may still be somewhat more susceptible than thermally modified Ash.
3. Environmental Impact
Both thermally modified Ash and Pine are environmentally friendly options. The thermal modification process itself is chemical-free, relying solely on high temperatures to alter the wood's properties. Arbor Wood Co sources all of its lumber domestically within the USA through responsibly managed forests.
Thermally Modified Ash: Using thermally modified Ash can help promote sustainable forestry practices. However, Ash trees have been threatened by pests like the Emerald Ash Borer, making sourcing a bit more challenging.
Thermally Modified Pine: Pine is generally more abundant and grows faster than Ash, making it a more readily available and sustainable resource. Pine plantations are common, ensuring a consistent supply without significant ecological disruption.
In conclusion, both options bring the benefits of thermal modification, offering enhanced performance and sustainability. By understanding their distinct characteristics, you can select the wood that best fits your project’s requirements.
