Cumaru Decking

Cumaru decking — commonly marketed as Brazilian Teak — delivers approximately 90% of Ipe's performance at a notably lower price, making it the smartest choice for homeowners and contractors who want premium hardwood decking without the premium price tag. With a Janka hardness of 3,330 lbf, Cumaru is harder than nearly every other commercially available decking species and only slightly below Ipe.

The wood's natural density and oil content provide inherent resistance to rot, decay, mold, and insect infestation — all without chemical treatments. Like Ipe, Cumaru carries a Class A fire rating, meeting the strictest building code requirements for fire-prone regions and commercial installations. These properties make Cumaru deck boards a reliable, long-lasting foundation for any outdoor living space.

Freshly milled Cumaru displays a range of warm reddish-brown to golden-tan tones, often with attractive color variation between boards that creates a visually dynamic deck surface. This natural color variation is a hallmark of authentic Brazilian Teak and is embraced by designers for its organic character. Over time, untreated Cumaru weathers to the same distinguished silver-gray patina as Ipe, or can be maintained with annual UV-protective oil to preserve the original warm tones.

Cumaru decking excels in residential patios, elevated decks, pool surrounds, and commercial applications where durability and budget both matter. It's particularly popular among contractors who recommend it to clients as the step-up from composite that delivers genuine hardwood quality at a manageable investment.

Compared to composite decking, Cumaru offers a natural look and feel, significantly longer lifespan (50+ years vs 25-30 for composites), and better scratch resistance. Against pressure-treated pine, the comparison is even more dramatic — Cumaru lasts three to five times longer and never requires the chemical retreatments that pressure-treated wood demands. Cumaru is responsibly harvested from managed forests in South America.
