1x6 Massaranduba Siding — Frequently Asked Questions

A 1x6 Massaranduba board weighs approximately 2.01 lbs per linear foot. Massaranduba has a density of about 69 lbs/ft³, making it one of the densest commercially available hardwoods. A 12-foot 1x6 Massaranduba board weighs approximately 24 lbs. Always factor weight into your structural and shipping calculations.

1x6 Massaranduba siding has an expected service life of up to 50+ years when properly installed. This is 3-5× longer than pressure-treated pine and 2-3× longer than cedar. Massaranduba achieves this exceptional longevity through its 3,190 Janka hardness and Class 1 durability rating, providing built-in resistance to rot, decay, insects, and fungal growth without chemical preservatives.

1x6 Massaranduba 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, Massaranduba's up to 50+-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 Massaranduba wood siding outperforms composite in hardness (3,190 vs ~200 Janka), lifespan (up to 50+ years vs 25-30 years), and heat resistance. Unlike composites, Massaranduba won't melt, warp in extreme heat, or fade significantly. While initial cost is similar ($8-15/LF installed), Massaranduba wood decking costs less over its much longer lifetime. Composites do offer lower upfront maintenance, but Massaranduba's natural beauty and durability make it the superior long-term investment.

Massaranduba is widely considered one of the best woods for 1x6 siding boards. With a 3,190 Janka hardness rating, Class A fire-rated certification, and up to 50+-year lifespan, Massaranduba (Brazilian Redwood) outperforms nearly every other commercially available wood species. Other excellent options include Cumaru (Brazilian Teak) and Massaranduba (Brazilian Redwood), but Massaranduba remains the industry benchmark for premium outdoor hardwood applications.

Massaranduba 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.

Massaranduba is DIY-friendly with proper preparation. Key requirements: (1) Always pre-drill all screw holes — Massaranduba 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 Massaranduba 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 Massaranduba. We work only with suppliers who follow responsible forestry practices with full chain-of-custody transparency. Note: We are not FSC certified. Massaranduba trees grow naturally in diverse tropical forests and regenerate well under managed harvest. The extremely long lifespan (up to 50+ years) means fewer replacements compared to softwood or composite alternatives, reducing long-term environmental impact.

1x6 Massaranduba Siding — Complete Buyer's Guide

Massaranduba, also known as Brazilian Redwood, is a premium tropical hardwood sourced from Northern South America (Brazil, Suriname, Venezuela). With a Janka hardness rating of 3,190 lbf and a density of 68 lbs/ft³, Massaranduba is classified as Class 1 - Very Durable — one of the most durable commercial lumber species available. The heartwood exhibits deep red to reddish-brown with straight to interlocked grain, fine to medium texture, creating a striking natural appearance that improves with age.

Why Choose 1x6 Massaranduba Wood for Your Siding?

As exterior cladding, Massaranduba 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 Massaranduba siding delivers a service life of 50+ years with minimal maintenance — an optional annual oil treatment preserves the original color, or you can let the Massaranduba wood weather to a distinguished silver-gray patina. Massaranduba carries a Class A - Low flame spread, making it suitable for wildfire-prone regions where code-compliant materials are required.

The 1x6 eased-edge (E4E) profile features gently rounded edges on all four sides, reducing the risk of splinters and creating a comfortable walking surface. This is the most versatile profile — suitable for face-screw installation with countersunk stainless steel fasteners. All Massaranduba lumber is available in Select and Better grade with lengths ranging from 4′ to 20′. For detailed step-by-step instructions, consult our Massaranduba installation guide. Long-term care recommendations are covered in our Massaranduba maintenance guide.

  • Board weight: A 12-foot 1x6 Massaranduba board weighs approximately 24 lbs (1.98 lbs/LF)
  • Coverage: Each 12-foot 1x6 board covers 5.5 sq ft of siding surface (5.5" face width)
  • Pre-drilling required: Always pre-drill in Massaranduba — the 3,190 lbf hardness prevents direct screwing

1x6 Massaranduba Siding — Frequently Asked Questions

1x6 Massaranduba siding has an expected service life of 50+ years when properly installed and maintained. This is 3-5x longer than pressure-treated pine and 2-3x longer than cedar. Massaranduba achieves this exceptional longevity through its natural density (Janka hardness: 3,190 lbf) and Class 1 durability rating, which provide built-in resistance to rot, decay, insects, and fungal growth — all without chemical preservatives.

Use 305 or 316 stainless steel screws for all Massaranduba installations — never use galvanized or coated deck screws, which will corrode and stain the wood. Pre-drill every hole using a countersink bit sized for your screw. For 1x6 boards, place screws approximately 1" from each edge and 3/4" from board ends. A combination drill/driver with a clutch setting prevents over-driving into this extremely hard wood.

1x6 Massaranduba siding pricing varies by profile, grade, and board length. 1x6 E4E boards in Select and Better grade typically range from $4-$12 per linear foot before shipping. While the upfront cost is higher than pressure-treated lumber, Massaranduba's 50+ years service life makes the lifetime cost per year significantly lower.
