How Much Do Stacker Doors Cost in Brisbane?

In Brisbane, stacker doors start at about $1,565 for a small 3-panel model and can go over $3,400 for a large 6-panel centre-opening door. The price difference isn't just about width. It also depends on how many panels the door has and how the width is divided between them.

If you’ve noticed that two stacker doors of similar size can have very different prices, this is the detail most guides leave out.

Key takeaways

• Stacker doors are more expensive than standard two-panel sliding doors because they use more glass, extra hardware, and a stronger track.
• The number of panels affects the price just as much as the width. A 3-panel stacker and a 6-panel stacker, even if they’re similar in size, are very different products.
• Centre-opening stacker doors cost more than same-side stacking ones because you’re paying for two fixed panels and four moving panels, instead of just one fixed and two moving panels.
• Even with the same number of panels, a wider 3-panel stacker will cost more than a narrower one, even though the panel count doesn’t change.

So, what actually makes a door a "stacker"?

A standard sliding door has two panels: one is fixed and the other slides. A stacker door adds more panels, allowing for a much wider opening. When open, the moving panels slide back and stack against the fixed panel or panels.

A&D offers two main types of stacker doors. The first is same-side stacking, which has one fixed panel and two sliding panels that stack over it. These are usually 3-panel stacker doors. The second type is centre-opening, with a fixed panel at each end and four sliding panels in the middle that stack back in pairs, creating a large opening in the centre of the wall.

This difference in structure, more than just the width, is the main reason for the range in stacker door prices.

Here’s a look at what stacker doors really cost, and why prices can vary so much.

Here are the current prices for same-side, 3-panel stacker doors in new stock, from smallest to largest (all prices include GST):

• 2100h x 2238w: $1,565
• 2100h x 2688w: $1,740
• 2100h x 3138w: $1,885
• 2100h x 3588w: $2,080
• 2100h x 4038w: $2,240

All of these are 3-panel doors. The price goes up by hundreds of dollars as the panels get wider, because larger sheets of toughened glass and longer aluminium sections cost more to make, even if you don’t add another panel.

Now, let’s compare those to centre-opening 6-panel stacker doors:

• 2100h x 4446w: $2,805
• 2100h x 5346w: $3,125
• 2100h x 6246w: $3,425

The smallest 6-panel stacker ($2,805) costs more than the largest 3-panel stacker ($2,240), even though they’re less than half a metre apart in width. The main reason is the number of panels. Six panels means twice as much moving glass, twice as many rollers, and a heavier track to support everything.

Whatever the configuration, aluminium doors sold in Australia need to meet AS2047, the standard covering windows and external glazed doors. The Australian Glass and Window Association has a straightforward explainer if you want the detail.

How to choose the right size and configuration for your space

Once you have an idea of the panel count and width you need, the quickest way to get an accurate price is to see what’s in stock, instead of starting a custom order. Panel count, width, and glass all affect the price, so two doors that look similar in a photo can actually be a thousand dollars apart.
