Product Overview
The Vanman SL55 is a high-performance hurricane shutter system featuring a triple bank louver design engineered to resist storm-driven rain and wind. This stormproof solution is AMCA 550 certified and ideal for coastal buildings, infrastructure, and mechanical rooms in hurricane-prone zones. SL55 louvers are tested for high wind speed rain resistance and air performance, making them suitable for areas with wind speeds up to 22 m/s and rainfall of 202 mm/h. Under such conditions, they maintain a rain resistance of 99% at a core wind speed of 3.5 m/s while ensuring effective airflow control.
