Overview

End Grain Balsa

Kiln-dried end grain balsa panels for the core of composite sandwich structures: wind turbine blades, boat hulls and decks, and other lightweight laminates.

The grain runs through the panel thickness, which gives high compressive strength for the weight. Supplied rigid, or flexible with glass-fibre scrim and slits to follow curved surfaces.
