The VL-SLV is a high-performance vertical weather louvre engineered for secure ventilation applications. Its best-in-class rain defence blades are aerodynamically profiled to minimise pressure loss while maintaining excellent airflow. Integrated stainless steel security bars are concealed within the aluminium blade profiles, delivering robust resistance to forced entry without compromising aesthetics. All fixings are fully enclosed within the frame, preventing tampering or removal after installation. Bird and insect mesh can be added internally, and no additional external security screen is required.
