1x6 Tigerwood Tongue & Groove Soffit — Frequently Asked Questions

A 1x6 Tigerwood board weighs approximately 2.01 lbs per linear foot. Tigerwood has a density of about 58 lbs/ft³, making it one of the densest commercially available hardwoods. A 12-foot 1x6 Tigerwood board weighs approximately 20 lbs. Always factor weight into your structural and shipping calculations.

1x6 Tigerwood soffit 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. Tigerwood achieves this exceptional longevity through its 2,160 Janka hardness and Class 1 durability rating, providing built-in resistance to rot, decay, insects, and fungal growth without chemical preservatives.

1x6 Tigerwood soffit 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, Tigerwood'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 Tigerwood wood soffit outperforms composite in hardness (2,160 vs ~200 Janka), lifespan (up to 40+ years vs 25-30 years), and heat resistance. Unlike composites, Tigerwood won't melt, warp in extreme heat, or fade significantly. While initial cost is similar ($8-15/LF installed), Tigerwood wood decking costs less over its much longer lifetime. Composites do offer lower upfront maintenance, but Tigerwood's natural beauty and durability make it the superior long-term investment.

Tigerwood is widely considered one of the best woods for 1x6 soffit boards. With a 2,160 Janka hardness rating, Class A fire-rated certification, and up to 40+-year lifespan, Tigerwood (Goncalo Alves) outperforms nearly every other commercially available wood species. Other excellent options include Cumaru (Brazilian Teak) and Massaranduba (Brazilian Redwood), but Tigerwood remains the industry benchmark for premium outdoor hardwood applications.

Tigerwood 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.

Tigerwood is DIY-friendly with proper preparation. Key requirements: (1) Always pre-drill all screw holes — Tigerwood 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 Tigerwood 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 Tigerwood. We work only with suppliers who follow responsible forestry practices with full chain-of-custody transparency. Note: We are not FSC certified. Tigerwood 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 Tigerwood Soffit — Frequently Asked Questions

1x6 Tigerwood soffit has an expected service life of 40+ years when properly installed and maintained. This is 3-5x longer than pressure-treated pine and 2-3x longer than cedar. Tigerwood achieves this exceptional longevity through its natural density (Janka hardness: 2,160 lbf) and Class 1 durability rating, which provide built-in resistance to rot, decay, insects, and fungal growth — all without chemical preservatives.

1x6 tongue & groove Tigerwood boards interlock via a milled tongue on one edge and a corresponding groove on the other. Secure each board by blind-nailing through the tongue at a 45° angle using stainless steel ring-shank nails or by face-screwing with countersunk stainless steel screws. Always pre-drill holes in Tigerwood to prevent splitting. T&G Tigerwood should only be used in covered or semi-protected areas.

1x6 Tigerwood soffit pricing varies by profile, grade, and board length. 1x6 Tongue & Groove 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, Tigerwood's 40+ years service life makes the lifetime cost per year significantly lower.
