5/4x8 Jatoba Siding

A 5/4x8 Jatoba board weighs approximately 3.53 lbs per linear foot. Jatoba has a density of about 57 lbs/ft³, making it one of the densest commercially available hardwoods. A 12-foot 5/4x8 Jatoba board weighs approximately 34 lbs. Always factor weight into your structural and shipping calculations.

5/4x8 Jatoba siding has an expected service life of up to 40+ years when properly installed. This is 3-5× longer than pressure-treated pine and 2-3× longer than cedar. Jatoba achieves this exceptional longevity through its 2,350 Janka hardness and Class 1 durability rating, providing built-in resistance to rot, decay, insects, and fungal growth without chemical preservatives.

5/4x8 Jatoba siding pricing varies by profile, grade, and board length. Select and Better grade boards typically range from $4-$12 per linear foot before shipping. While the upfront cost is higher than pressure-treated lumber, Jatoba's up to 40+-year service life makes the lifetime cost per year significantly lower.

Yes — 5/4x8 Jatoba wood siding outperforms composite in hardness (2,350 vs ~200 Janka), lifespan (up to 40+ years vs 25-30 years), and heat resistance. Unlike composites, Jatoba won't melt, warp in extreme heat, or fade significantly. While initial cost is similar ($8-15/LF installed), Jatoba wood decking costs less over its much longer lifetime. Composites do offer lower upfront maintenance, but Jatoba's natural beauty and durability make it the superior long-term investment.

Jatoba is widely considered one of the best woods for 5/4x8 siding boards. With a 2,350 Janka hardness rating, Class A fire-rated certification, and up to 40+-year lifespan, Jatoba (Brazilian Cherry) outperforms nearly every other commercially available wood species. Other excellent options include Cumaru (Brazilian Teak) and Massaranduba (Brazilian Redwood), but Jatoba remains the industry benchmark for premium outdoor hardwood applications.

Jatoba requires minimal maintenance. Without treatment, it naturally weathers to an elegant silver-gray patina over 6-12 months. To maintain the original warm brown color, apply a UV-inhibiting penetrating oil (like Ipe Oil or Penofin) once or twice annually. Cleaning involves periodic washing with a mild soap solution. No sanding, staining, or sealing is required for structural durability.

Jatoba is DIY-friendly with proper preparation. Key requirements: (1) Always pre-drill all screw holes — Jatoba is too hard for direct screwing. (2) Use only 305 or 316 stainless steel fasteners — standard hardware will corrode and stain. (3) Face-screw with stainless steel trim-head screws. (4) Allow boards to acclimate on-site for 5-7 days before installation. A compound miter saw with a carbide-tipped blade is recommended.

A nominal 5/4x8 Jatoba board has actual finished dimensions of 1" × 7.25" (25.4 x 184.1 mm). The "5/4x8" is the nominal (rough-cut) size — after kiln drying and precision surfacing, all hardwood lumber finishes slightly smaller. This is standard across the lumber industry, similar to how a nominal 2×4 softwood measures 1.5" × 3.5". Always use the actual dimensions (1" × 7.25") when calculating material quantities and coverage for your project.

We responsibly, legally, and ethically source all our Jatoba. We work only with suppliers who follow responsible forestry practices with full chain-of-custody transparency. Jatoba trees grow naturally in diverse tropical forests and regenerate well under managed harvest. The extremely long lifespan (up to 40+ years) means fewer replacements compared to softwood or composite alternatives, reducing long-term environmental impact.
