EG Balsa Products

End-grain (EG) Balsa is a highly processed, ultra-light, engineered wood product for use in composite sandwich construction. It has an extremely high strength to weight ratio and is resistant to crushing, shearing, and delamination. Our end-grain balsa panels offer superior performance and strength in weight-sensitive applications. EG Balsa products are available in standard 24” x 48” panels with optional 48″ x 48″ panels in limited finishes and thicknesses.

Only I-Core structural core panels feature PlyScrim 100™. In scrimmed panels, the scrim will be flush with the surface, and the adhesive is compatible with virtually all resin systems. We can also apply ARMOR® coating to any of our Balsa products, which inhibits the growth of bacteria, mold, and fungi; reduces resin uptake; and achieves excellent laminate and bond strength.
