Balsa core is a remarkable material known for its lightweight and high strength-to-weight ratio, making it ideal for various applications, including boats and wind turbines, and as a core material in composites.
At Sky Composites, we prioritize eco-friendly practices through our subsidiary, Cobalsa, located in Ecuador. With over 50 years of experience, Cobalsa is dedicated to cultivating balsa trees sustainably, ensuring a continuous supply of A-grade end-grain balsa wood. Ecuador supplies more than 95% of the world’s balsa wood, highlighting its significance in the global market.
What makes balsa wood sustainable?
Balsa trees are among the fastest-growing hardwood species, reaching maturity in just 4 to 5 years and heights up to 90 feet. This rapid growth allows for frequent harvesting without depleting forest resources.
Additionally, balsa trees act as effective carbon sinks, absorbing significant amounts of carbon dioxide (CO₂) from the atmosphere, thus contributing to climate change mitigation.

Responsible harvesting practices at Cobalsa, our manufacturing facility in Ecuador
Cobalsa employs responsible harvesting methods, including selective cutting, which involves carefully choosing specific trees for harvest while preserving the surrounding ecosystem. This approach minimizes habitat disruption, supports biodiversity, and maintains ecological balance. Furthermore, our commitment to replanting ensures that for every tree harvested, new trees are planted, promoting forest regeneration and sustainability.
Look for different certifications for sustainable balsa
To validate sustainable practices, we adhere to rigorous standards. Our balsa wood is sourced from responsibly managed forests that meet strict environmental, social, and economic criteria. This commitment protects biodiversity, upholds the rights of local communities, and promotes sustainable forest management.
