Tropical Hardwood Technical Data Sheets
Technical data sheets (TDS) for Ipe, Cumaru, Tigerwood, Garapa, and Massaranduba wood. Janka hardness, density, MOE/MOR, shrinkage rates, fire ratings, and downloadable span charts — built for architects, engineers, and contractors who need the numbers.
Density
Weight per cubic foot. Higher density = harder, more durable wood.
MOE / MOR
Modulus of Elasticity (stiffness) and Modulus of Rupture (breaking strength).
Janka Hardness
Force required to embed a steel ball into the wood. Industry standard for hardness.
Fire Rating
ASTM E84 flame spread classification. Class A is the highest rating for building materials.
Wood Species Technical Data — Properties & Specifications
Mechanical and physical properties from each species' technical data sheet. Values are published averages based on standard test conditions (ASTM, USDA FPL) and may vary by individual board.

Fire Rating & Building Code Notes
Ipe has been independently tested under ASTM E84 and has achieved a Class A flame spread rating (flame spread index ≤ 25), which is the highest classification for building materials — comparable to steel and concrete. This makes Ipe one of the only natural woods that can meet WUI (Wildland-Urban Interface) code requirements in many jurisdictions without chemical treatment.
Cumaru has also achieved Class A results in independent third-party ASTM E84 testing, though results may vary by specific sample and test conditions. Check with your local building department for accepted test reports.
† Species marked as "Not independently tested" have not undergone ASTM E84 testing to our knowledge. This does not mean they are unsafe — only that no standardized fire test data is currently published for these species. Always verify local code requirements and consult your Authority Having Jurisdiction (AHJ) before specifying any material for fire-rated assemblies.
Fire performance can be influenced by board thickness, installation method, finish coatings, and environmental conditions. Ipe Woods USA does not guarantee any specific fire rating for any product. Consult a fire protection engineer for project-specific requirements.
