Description
Sheet, 3/8in. Balsa Core 24" x 48" Grid Scored, Standard Density ( 9.5lbs cu. ft.)
End grain balsa sheets are often used where high physical properties are required in a composite sandwich core. Balsa exhibits very high sheer strength properties and transfers stress from one skin to the other very well. Works very well in areas that are subject to point impacts such as decks.
Other thicknesses or types available by special order (minimums apply).
Properly installed it will last for decades without rot or degradation. Issues with balsa rotting out are related to improper installation, i.e. not filling kerfs or leaving channels for water to flow through, or impropper bedding of deck hardware or penetrations.
