How Stacking Patio Doors Operate

Stacking patio doors operate using multiple sliding panels that move smoothly along a low-profile track and stack together at one side – or both sides – of the opening.

Unlike traditional patio doors that limit access to a small portion of the opening, stacking doors maximise usable space and create a true indoor-outdoor transition.

• 3-Panel patio doors – All three panels glide and stack to the left OR right, depending on the preferred layout.
• 6-Panel patio doors – Panels meet in the centre and then slide outward, stacking three panels to each side for a dramatic, balanced opening.

This creates a vast and flexible entryway that feels open, bright, and tailored to your outdoor living needs – whether it’s a private balcony or a spacious backyard with a view.
