The Best Kept Secret in Wood Siding: Unveiling Four Hidden Gems

When you think of wood siding, classics like Western Red Cedar or redwood might come to mind—but there’s a quartet of lesser-known options that deserve your attention. Incense cedar, thermally modified radiata pine, Accoya, and ambarra (also known as Cambara or Brazilian mahogany) are quietly revolutionizing the cladding game. These woods bring unique benefits to the table, from durability to sustainability, all while adding distinctive charm to your home.

1. Incense Cedar: The Aromatic All-Rounder

Incense Cedar: The Aromatic All-Rounder Incense cedar (Calocedrus decurrens) isn’t as famous as its Western Red cousin, but it’s a powerhouse in its own right. Native to the western U.S., this wood gets its name from its spicy, aromatic scent—a bonus that makes working with it a sensory delight. As cladding, incense cedar shines with natural resistance to rot, insects, and weathering, thanks to its rich oil content. Its warm, reddish-brown hues deepen over time, offering a subtle elegance that fits both rustic and modern designs. Low-maintenance and lightweight, it’s an unsung hero for homeowners who want durability without the fuss. Plus, it’s a sustainable choice, often sourced from well-managed forests.

2. Thermally Modified Radiata Pine: The High-Heat Wonder

Radiata pine on its own is a fast-growing, budget-friendly softwood, but when thermally modified, it transforms into a cladding superstar. This process involves heating the wood to extreme temperatures (around 350-400°F) in a low-oxygen environment, which strips away moisture and sugars that attract rot and pests. The result? A darker, richer tone—think caramel to chocolate brown—and enhanced stability that resists warping and swelling. Thermally modified radiata pine offers cedar-like durability at a fraction of the cost, making it a secret weapon for exterior siding that punches above its weight.

3. Ambarra (Cambara): The Tropical Charmer

Ambarra, often called Cambara or Brazilian mahogany, is a South American hardwood that’s still flying under the radar for many. With a reddish-brown color reminiscent of true mahogany, it brings a touch of tropical sophistication to any home. Ambarra’s natural durability makes it resistant to moisture and insects, ideal for exterior cladding in humid or coastal areas. It’s denser than cedar but easier to work with than ultra-hardwoods like Ipe, striking a sweet spot for both practicality and beauty. Over time, it weathers to a distinguished silver-gray, adding character without compromising strength.

4. Accoya: The Engineered Marvel

Accoya isn’t your average wood—it’s a high-tech masterpiece made from acetylated radiata pine. Through a chemical process, the wood’s cell structure is altered to become virtually impervious to water, rot, and insects. The payoff is cladding that can last 50 years or more, even in brutal climates, with almost no maintenance. Its pale, uniform finish takes stains or paints beautifully, or you can leave it natural for a clean, modern look. Accoya’s eco-credentials are solid too—non-toxic and sourced from renewable plantations. It’s the cladding equivalent of a luxury car: premium, yes, but built to last.

Why These Woods Are a Secret Worth Sharing

What sets these options apart is their blend of performance and personality. Incense cedar offers aromatic appeal and easy upkeep. Thermally modified radiata pine delivers high-end durability on a budget. Accoya pushes the boundaries of what wood can endure, while ambarra brings exotic flair with workhorse reliability. They’re not as mainstream as cedar or pine, but that’s part of their charm—choosing one feels like being in on an insider tip.

Which One’s Right for You?

• Budget-conscious? Thermally modified radiata pine keeps costs down without skimping on quality.

• Low maintenance? Incense cedar and Accoya require almost no upkeep.

• Unique aesthetics? Ambarra’s tropical tones or Accoya’s sleek versatility stand out.

• Sustainability? All four are responsibly sourced, with Accoya and incense cedar leading the eco-friendly pack.

Incense cedar, thermally modified radiata pine, Accoya, and ambarra might not be household names—yet—but they’re proof that the best siding solutions don’t always shout the loudest. Each brings something special to the table, whether it’s scent, science, or South American soul. If you’re ready to elevate your home with cladding that’s as smart as it is stunning, these hidden gems are worth a closer look.
