Lighter in weight than any other wood, yet still strong, these balsa cores stiffen composite sandwiches without weighing them down. They resist damage from impact and repeated use. Because they don’t let heat or sound pass through quickly, these cores are good natural insulators. They also resist chemicals. All come from balsa trees grown in FSC (Forest Stewardship Council) certified forests. They cannot be sold to Canada due to import regulations.

Flexible cores are best for forming complex shapes.
