Exterior Sun Louvres – SL4 /SL5 and H-3 Type.

The Exterior Sun Louvres – SL4 / SL5 and H-3 Type system is a high-performance architectural shading solution designed to enhance the energy efficiency, aesthetics, and thermal control of modern buildings. These louvres are engineered to minimize solar heat gain while allowing natural daylight and ventilation to pass through, making them ideal for both commercial and institutional facades.
Manufactured using high-grade extruded aluminum profiles, the louvres are available in SL4 (angled slim fins), SL5 (wider rectangular fins), and H-3 (hollow box-shaped) configurations to suit various design and functional requirements. The louvre system supports both fixed and operable installations and can be customized with multiple gap configurations, tilt angles, and finishes including PVDF, powder coating, and anodizing. Known for durability, lightweight construction, and sleek appearance, these louvres are widely used for sun control, privacy screening, and enhancing façade aesthetics.
