Ultimate Weather Protection Louvre

Designed for superior rain protection, the VL-3SD features a three-stage blade system and a two-piece pressure-equalised mullion for effective water management. The shallow 150mm frame depth ensures easy integration into facades, and clip-fixed front blades allow for large-scale, uninterrupted louvre spans. This versatile system is ideal for applications in hospitals, data centres, and apartment buildings where both performance and design flexibility are essential.
