What Are Some of the Lightest Woods?
Although balsa wood is extremely light, it is actually a hardwood. Depending on the variety, it typically ranges from 6 to 14 lbs. per cubic foot and has a high strength to weight ratio. It is best known as the wood used in model airplanes. Balsa absorbs shocks and vibrations well and is easy to cut and shape with hand tools. Balsa trees grow very quickly, reaching 60 to 90 feet with a 12- to 45-inch diameter in six to 10 years. Balsa is also employed in surfboards, flotation devices and insulation.
