French Company Working on Bio-Based Framing

April 26, 2011

A composite window profile combining thermoset resins and flax fibers is being developed by Innobat, a French research and development company working in the green building arena. The technology was recently recognized with an Innovation Award in the bio-based materials category at the JEC Composites Show, an international event for the composites industry held in Paris in March.


 Innobat's pultruded bio-based composite

Consisting of 65 percent flax fibers, the composite is currently being pultruded as a simple, square tube profile, says Michel Maugenet, Innobat president. The next step is to produce a more complex shape like a window profile, he notes, and the French company is currently looking for profile manufacturers that would be interested in partnering with it on such efforts.

The bio-based composite is seen offering higher strength than PVC or wood and thermal performance much better than aluminum. Due to the use of flax fibers, which are a natural and renewable resource, the material would score better than other alternatives in life cycle assessments, the company notes.
