Balsa Core Grid Scored

End Grain Balsa, a highly processed ultra light wood product, imparts impressive strength and stiffness to the sandwich panel. The end grain configuration of balsa provides high resistance to crushing, and is very difficult to tear apart. End grain balsa cored panels also have the ability to handle excessive dynamic loads with high resistance to fatigue.

Until recently, end grain balsa was excluded from some weight sensitive applications, as there were lower density foam cores available.

Now, through controlled growing and careful selection, Balsa is competitive in weight, as well as offering superior performance in stiffness and strength, particularly where local crushing or bruising is a concern. Balsa is select quality, kiln-dried, end-grain balsa wood suitable as a structural core material in composite sandwich construction.
