Balsa wood

When high performance is required at minimal weight, sandwich structures are the ideal solution. By bonding thin, strong skins to a lightweight core, they achieve an outstanding stiffness-to-weight ratio and excellent buckling resistance. Sky Composites supplies a full portfolio of structural core materials for marine, wind, transportation, and construction applications, supporting engineers from concept through production.

Balsa core remains one of the most trusted materials in structural composite manufacturing — valued for its natural strength, low weight, and renewable origin.
