Stacking Doors

Stacking doors are designed to create wide, open spaces with a seamless connection between indoors and outdoors. The stacking door’s slimline frame allows abundant natural light, unobstructed views, and refreshing breezes to cascade in through expansive glass panels—up to six metres wide. As the panels slide and stack neatly behind one another, they provide maximum opening space while maintaining a clean, modern look. Ideal for large openings, stacking doors combine elegance, functionality, and effortless operation without compromising energy efficiency or ease of maintenance.

Stacking doors are multi-panel sliding doors where each panel stacks neatly behind the next, creating a wide, open entryway to outdoor areas.
