Product Overview
The Togen SL46V is a heavy-duty single bank aluminium louvre engineered for hurricane-prone regions. Each blade is integrally formed with three screw holes for secure installation, ensuring the louvers remain stable without vibration under extreme wind pressure. Featuring an inverted U-shaped profile with dedicated drainage holes, SL46V efficiently collects and directs rainwater for rapid discharge. Tested under AMCA 500 high-velocity wind-driven rain conditions, the SL46V balances safety, strength, and ventilation.
