Facts About Paulownia
Paulownia is native to Southeast Asia but it is used throughout the world with a number of uses from construction to, surfboards to bio-fuel.
Paulownia wood is knot free, which greatly reduces wastage and makes it a good choice for many applications such as our wooden surf and stand up paddleboards.
Paulownia wood is also the lightest known timber other than balsa. It is around two-thirds of the weight of the lightest commercial wood currently being grown in Europe. It’s a third of the weight of Oak and half the weight of Pine. Perfect material for building a paulownia surfboard.
Paulownia wood also has the highest strength to weight ratios of any wood in the world. Auburn University tested the strength of 18lbs p/cubic ft. against balsa with an average weight of 10lbs p/cubic foot.

Wooden Paulownia Surfboard Facts
Hollow wooden surfboards are made of wood and Epoxy. Hollow wooden surfboards particularly have no foam in their development. (Sheets made with foam and wood are normally known as compounds or polish sheets.) Various development strategies are utilized within the surfboard and help reduce the heaviness of the finished board. By and large, hollow wood surfboards are generally 30% to 60% heavier than a standard foam surfboard.
Paulownia has been thoroughly tested and found to have a higher strength to weight ratio than Balsa!
Auburn University tested the strength of 18 lb p/cubic ft. Paulownia against Balsa, with an average weight of 10 lbs p/cubic foot.
Some Balsa core material is sliced at 3/8 inch with end-grained material. Paulownia can be cut at 3/16 and offer approximately the same strength and weight. Paulownia offers a space-saving benefit, being cut half as thick. There is also a significant cost saving because half as much material is needed.
Lighter grades of Paulownia weigh only 14lbs per cubic foot. This is lighter than many Balsa grades.
When considering the large amount of epoxy that Balsa soaks up, Paulownia gains an even larger weight advantage.
Paulownia is easily carved and can hold nails and screws without splitting. It also provides greater stability and flexibility for making molds and models.
Paulownia weighs an average of 250 to 305 KGs per cubic meter making it half the weight of Pine.
