Jatoba is a premium tropical hardwood sourced from Central & South America (Brazil, Peru, Bolivia). With a Janka hardness rating of 2,350 lbf and a density of approximately 60 lbs/ft³, Jatoba is classified as Class 1-2 - Durable — one of the most durable commercial lumber species available.
Why Choose 5/4x6 Jatoba Wood for Your Siding?
As exterior cladding, Jatoba siding provides a weather-tight barrier with exceptional impact resistance. The dense grain resists dents, hail damage, and woodpecker damage far better than cedar, pine, or fiber cement alternatives. Properly installed 5/4x6 Jatoba siding delivers a service life of 40+ years with minimal maintenance — an optional annual oil treatment preserves the original color, or you can let the Jatoba wood weather to a distinguished silver-gray patina. Jatoba carries a Class A - Low flame spread, making it suitable for wildfire-prone regions where code-compliant materials are required.
The 5/4x6 profile is precision-milled to tight tolerances and available in Select and Better grade, ensuring consistent quality across your entire project. All Jatoba lumber is available in Select and Better grade with lengths ranging from 4′ to 20′.
