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 1x3 Jatoba Wood for Your Soffit?
Jatoba soffit and porch ceiling boards create a warm, premium overhead aesthetic that vinyl and aluminum simply cannot replicate. The natural grain pattern adds architectural character to any covered outdoor space. Properly installed 1x3 Jatoba soffit 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 1x3 shiplap profile creates an overlapping joint with a distinctive shadow line between boards. Popular for siding, accent walls, and architectural cladding applications. All Jatoba lumber is available in Select and Better grade with lengths ranging from 4′ to 20′.
