Balsa is the lightest commercial wood -- approximately one-sixth the weight of oak. Despite being classified as a hardwood, it cuts cleanly with a hobby knife. The standard material for model building, prototyping, and minimum-weight applications. Available at Windsor Plywood locations across Canada.

Pro Tips
- Balsa is a modelling and prototyping material, not furniture or construction wood. Seal before finishing to prevent excessive absorption. Its near-zero weight and easy cutting are irreplaceable for model building.
- Acclimate lumber in your workspace for 48-72 hours before milling to allow the wood to adjust to ambient temperature and humidity.
Frequently Asked Questions
Is balsa really a hardwood?
Yes -- botanically. Balsa is a flowering, deciduous tree, which classifies it as hardwood. But at 100 lbf Janka, it is by far the softest commercial wood. The classification is botanical, not practical.
