The ALV-VOID 20 Curtain Wall System is the slimmest façade system in the range, defined by an ultra-minimal 20 mm visible sightline that maximises glazing and creates a clean, uninterrupted architectural appearance. Engineered with a 160 mm structural mullion, the system delivers the depth and strength required for expansive glazed elevations while maintaining refined proportions. Integrated pressure-cap glazing, concealed drainage, and high-performance gasket technology provide dependable weather resistance, durability, and long-term façade performance, making ALV-VOID 20 well suited to luxury residential, hospitality, and commercial applications.
ALV VOID is available in three track configurations to match project scale — from intimate courtyard openings to full-height living walls. Each configuration carries its own performance envelope, so the right variant can be matched precisely to the demands of the opening.
