Wheat straw wall panels.

This article presents information on wall panels, by Texas-based Durra Building Systems. To create their strawboard panels, Durra applies both high heat and extreme pressure to straw fibers, coaxing out resins that act as a permanent bonding agent. Panels are then dry-extruded and finished with a strong, water-resistant liner paper. The resulting panels are nontoxic and offer fire, impact, mold, and mildew resistance.
