EconoSpan® 22-1/2 degrees Pitched Louver

22-1/2° Pitched Louvered screens offer maximum visual concealment while allowing for adequate ventilation. This louver configuration allows for 30% free airflow, and the louver can be inverted (flipped upside down) to provide even more concealment from line of sight if needed. This very effective design is very attractive and convenient for large projects. Like all EconoSpan® louver products, they ship in knock-down kits complete with detailed installation instructions, and install quickly.
