CertainTeed Corp.: TURNING VANE
ToughGard™ turning vane is an IAQ-sensitive, molded, acoustical fiberglass turning vane that features a lower material and installed cost than metal turning vanes, says the company. The product is designed to be used primarily in commercial fiberglass duct board systems. The turning vane assists airflow around 90-degree elbows with minimal pressure loss. Unlike plain, molded fiberglass turning vanes, the product’s exterior surface is specially treated to prevent potential fiber erosion, the company says.
