End-Grain Balsa Core

Nature's Wonder-Wood For Composite Laminates


End-grain balsa wood is a structural core with ideal properties for sandwich construction. It is compatible with all types of manufacturing processes from wet lamination to pre-preg construction.


Balsa is not affected by styrene or long resin gel times making it well suited for infusion applications. You can purchase rigid balsa sheets or contour-cut with scrim as well as a variety of specialty cuts.


Balsa is also available with a coating that minimizes resin absorption increasing bond strength and maximizing your weight savings. Today’s balsa core is available with controlled density (5lb/cu. ft - 18lb/cu. ft) for making more precision parts.


Balsa is an economical solution to higher priced foam cores.

Balsa is also sustainably sourced and managed material with a low carbon footprint.
