1x6 Jatoba Shiplap Siding — Complete Guide

Everything you need to know about shiplap jatoba siding

About 1x6 Jatoba Shiplap Siding

Jatoba, often referred to as Brazilian Cherry, is a premium hardwood choice for exterior cladding due to its exceptional density and natural resistance to environmental decay. The shiplap profile is engineered to provide a clean, modern aesthetic characterized by uniform shadow lines that enhance the texture of a building facade. The interlocking nature of the shiplap profile accommodates minor dimensional movement while maintaining a protective barrier against moisture infiltration, making it suitable for both vertical and horizontal installation orientations.

  • Interlocking shiplap profile creates a consistent, sophisticated shadow line.
  • High natural density provides structural integrity for exterior applications.
  • Versatile installation allows for both horizontal and vertical siding layouts.
  • Exceptional resistance to environmental stressors and decay.

Key Benefits

Natural Decay Resistance

Jatoba contains natural oils and extractives that provide inherent protection against fungal decay, rot, and wood-boring insects without the need for chemical treatment.

Superior Hardness

With a Janka rating of 2350, this species offers excellent resistance to impact, dents, and surface abrasion common in high-traffic commercial or residential settings.

Aesthetic Versatility

The rich reddish-brown hues provide a sophisticated architectural appearance that transitions beautifully from modern to traditional design styles.

Technical Specifications

Installation Guide

Difficulty:
Professional/Advanced

Key Tips:

  • Pre-drilling is required due to the wood's high density to prevent splitting.
  • Allow for proper acclimation on-site before installation to stabilize moisture content.
  • Implement a rainscreen system to ensure adequate ventilation behind the cladding.
  • Use stainless steel fasteners to prevent corrosion and staining in exterior environments.

Recommended Tools:

High-speed carbide-tipped saw blades
Cordless impact driver with high-torque capacity
Countersink drill bits
Level and spacing jigs

Maintenance & Care

Cleaning

Regular cleaning with a soft-bristled brush and mild soap solution will remove debris and surface grime. Avoid high-pressure washing, which can damage the wood fibers.

Finishing

Apply a high-quality, penetrating UV-inhibiting oil finish to maintain the original color and prevent rapid graying caused by solar exposure.

Weathering

If left unfinished, Jatoba will naturally transition to a silver-grey patina over time; this process is purely cosmetic and does not compromise the structural integrity of the wood.

1x6 Jatoba Shiplap Siding — Frequently Asked Questions

A 1x6 Jatoba board weighs approximately 2.01 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 1x6 Jatoba board weighs approximately 20 lbs. Always factor weight into your structural and shipping calculations.

1x6 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.

1x6 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. Use the configurator above for exact pricing, or request a custom quote for large orders.

Yes — 1x6 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 1x6 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 1x6 Jatoba board has actual finished dimensions of 0.75" × 5.5" (19.0 x 139.7 mm). The "1x6" 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 (0.75" × 5.5") 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.

1x6 Jatoba Shiplap Siding — Complete Buyer's Guide

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 1x6 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 1x6 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 1x6 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′.
