DELIVERING THE FUTURE OF COMPOSITE SOLUTIONS
GURIT® BALSAFLEX™
gurit.balsa@gurit.com
www.gurit.com
Gurit® Balsaflex™ is a classic balsa wood core material with the best balance between
weight and resistance for sandwich construction. Its main features are:
¬ High quality composite core material made from end-grain balsa wood
¬ Exceptional shear and compressive strength
¬ From an ecological and renewable resource
¬ Suitable for wind energy, marine, transportation, industrial and other applications
¬ The composite can be produced using hand layup, pultrusion, infusion, pressed
moulding, etc
Balsa wood is the most ecological core material available on the market. Balsa trees are
grown on plantations, in five year cycles. Balsa is a self-generating species in Ecuador,
which means that it renews itself quickly without any risk of depletion.
Our production centre is located in a balsa wood producing area of Ecuador. From there,
we export directly all over the world. Our headquarters are located in Spain.
We are considered number one in quality worldwide. This has been achieved due to our
rigorous manufacturing process control and quality filters.
We started manufacturing Gurit® Balsaflex™ panels in 2002, under the company name
‘Balseurop’. In March 2011 we became part of Gurit Holding, and subsequently changed
our company name to ‘Gurit Balsa’.
STATE OF THE ART FACILITIES
After being cut, the balsa wood is kiln dried. This process ensures dimensional stability of the wood
and avoids any phytosanitary risk, guaranteeing the absence of non-desirable living organisms.
Strict moisture controls throughout our manufacturing process and the possibility of re-drying wood
during our process, allows us to ensure the required moisture content in our final products.
We have two warehouses with atmospheric-controlled environments that keep balsa glued blocks in
perfect conditions (independently of weather conditions) and ensure the ideal degree of moisture.
Gurit Balsa holds a large stock of glued blocks ready to be converted into panels; our current storage
capacity is up to 140 containers. This, in addition to two complete production lines used in our
manufacturing process, allows us to meet our commitments punctually throughout the whole year.
