A stable, rot-resistant Ash board thermally modified for outdoor use. Great for decks, cladding, and fences in modern or natural builds
Thermally modified Ash 1×6 boards are a highly durable, chemical-free option for exterior projects. They require long-lasting performance. These boards undergo a heat and steam treatment that stabilizes the wood. This makes it far more resistant to moisture, decay, and warping than untreated Ash. At the same time, this process preserves the woodโs natural beauty. It gives your projects a warm, inviting look without the need for harsh chemicals.
The finished size of 7/8″ x 5.11″ makes these boards ideal for a wide range of applications. They are especially well-suited for:
Decking, providing a sturdy, attractive surface that holds up in all weather conditions, and features thermally modified Ash materials.
Vertical cladding, adding a stylish and durable exterior layer to homes or buildings
Fencing, offering a long-lasting solution that resists rot and insect damage and uses modified Ash wood thermally for extra durability.
Soffits and trim work, giving a clean, finished appearance while maintaining structural integrity
These boards feature a smooth S4S E4E profile, which allows for easy installation and creates clean, precise lines. Their consistency in shape helps reduce installation time and minimizes the risk of warping, giving your project a professional, polished look.
The natural warm brown tone of thermally modified Ash boards develops a soft, elegant patina over time. If you prefer, you can apply a sealant to maintain the original color and enhance the woodโs durability even further. For projects that require flexibility, a random-length option measuring 7/8″ x 5.5″ is also available, making it easier to plan layouts with minimal waste.
Whether youโre building a deck, fence, or decorative cladding, thermally modified Ash 1×6 boards combine beauty, strength, and sustainability. They offer a long-term solution that performs exceptionally well in outdoor environments. The use of this type of Ash ensures a natural, classic appearance that complements any architectural style.

The quality of the IPE and other hardwoods was outstandingโeverything arrived on time and exactly as promised. Beyond Lumber truly cares about customer service and delivers top-notch products. Highly recommend them for anyone looking for premium decking and outdoor materials

I started buying IPE from Brazilian Lumber over one year ago before the vendor opened the California location (i.e. where I am located). There were some issues related to the lumber (IPE), BUT the vendor made sure that all was taken care of and that I was happy. I mentioned “the issues” not to say that they product is bad, but rather to stressed out that the vendor provides superb service. No matter what you do, the problems may happen. Important is how such situations are handled. I was working with Luis, great guy to work with. I recommend this vendor.

I upgraded my backyard with Ipe deck tiles for my patio. It was definitely an investment, but it’s turned out to be worth every penny. The tiles were easy to install and the finished product is not only beautiful, but also incredibly durable and functional. I would highly recommend Ipe deck tiles to anyone looking to create a beautiful and long-lasting outdoor space.

The best place to get Brazilian hardwood that I\’ve found anywhere in California or online. The customer service is very good, the reps are attentive to you upon arrival and they are very knowledgeable. The quality of wood is superb and the pricing is cheaper than I can find anywhere else.
