Overview

Professional Summary

Balsa (Ochroma pyramidale) is the lightest commercial timber in the world at just 9 lb/ft³ and 67 lbf Janka — lighter than most foams. Despite its extreme lightness, it has a remarkably high strength-to-weight ratio, making it essential for model aircraft, wind turbine blades, and lightweight composite sandwich cores.

In Plain English

Balsa is the lightest wood in the world — so light it almost floats in air. Everyone knows it from model airplanes and craft projects, but it's also critical for wind turbine blades and surfboards. You can cut it with a hobby knife and dent it with your fingernail.

Sources, Conditions & Safety

No documented references are attached to this profile yet. Its recorded values should not be treated as source-verified.

Wood dust & sensitivity

Species-specific safety information has not been documented here. Absence of a warning does not mean the wood is safe or non-allergenic.

Use dust extraction and appropriate protective equipment; consult occupational-safety guidance. This is not medical advice or food-contact approval.

Common Uses

Other

Model aircraft, surfboard cores, wind turbine blades, theatrical props, composite sandwich panels, and packaging.

Sustainability & Trade

Listings are reference information, not proof of legal sourcing or certification. Verify current trade rules and supplier documentation before buying; absence of a note does not mean unrestricted trade.

CITES StatusUnlisted
IUCN StatusNot Evaluated
Sourcing NotesFast-growing plantation species with 5-7 year harvest cycle. Ecuador is the primary producer. Highly sustainable.

Extremely fragile — no structural strength. Perishable without treatment. Absorbs moisture rapidly.
