WindStrand® 4000

WindStrand® 4000 Type 30® roving combines high weaving efficiency & superior pultruding processability with the power of a higher modulus glass. WindStrand® 4000 allows more efficient blade designs for the production of lighter, longer blades that reduces the cost of wind energy.

Ultrablade® 2 leverages the power of WindStrand® 4000’s higher modulus at increased Fiber Volume Fractions to improve laminate modulus in the main fiber direction. Ultrablade® 2 allows more efficient design for lighter, longer blades that reduce the the cost of wind energy.

Ultraspar™ 2 combines the higher performance of WindStrand® 4000 with the consistency of the pultrusion process, allowing efficient, cost-effective blade design and production. High-performance glass-pultruded profiles enable lighter, longer, stronger blades that reduce the cost

The ULTRASPAR™ pultruded planks, Glas-Powered™ by the Owens Corning® high-modulus glass family are designed to deliver more performance, part consistency, and an easier spar cap assembly experience.
