End Grain Balsa Core

Balsa is a naturally recurring Ecuadorian resource. The balsa plant grows from a seedling to a mature tree in 4-6 years reaching heights of up to 28 meters (90 ft) before coming to the end of its natural life. ProBalsa is high quality coring material made from end-grain balsa wood. Its end-grain, micro-honeycomb structure offers exceptional strength and stiffness. ProBalsa core can be supplied in flat sheets, in grid-scored form and as kits.
