Stacking Windows South Africa

Stacking Windows South Africa are sliding windows with three or more panels that run on their own tracks and gather to one side, so most of the opening clears rather than half of it. They suit a serving hatch onto a patio, a wide kitchen opening or any wall where you want the window out of the way. Say how wide the opening is and which side it should stack, and get priced quotations to compare.

Prices JUST UPDATED. Ballpark figures, rounded, excluding VAT. They reflect typical South African aluminium window, door and glazing rates, supplied and installed. They are not our prices or quotations, and no provider is bound by them. Aluminium is MADE TO ORDER, so a firm price follows a site measure rather than a drawing, and the system, the glass and the finish move a quotation further than the size does. Confirm what each quotation includes, such as removing the old frame, making good, and the glass type for every opening.

What a Stacking Window Quote Covers

The number of panels. Three, four or more, which sets how much of the opening clears.
The track. One track per panel, so a four panel window is a deeper frame than a two panel one.
Rollers. Carrying more panels over a wider span, so the rollers are doing more work.
The glass. Thickness by panel size, and safety glass where the position needs it.
Support over the opening. A wide opening needs a lintel that is already there and already adequate.

Where Quotes Differ Most

Panel count and width. Each extra panel is another track, another roller set and more profile.
Which side it stacks. It has to be decided before fabrication, and it changes the frame.
Whether the sill is flush. A low or flush track is harder to drain and costs more.
Glass size. Wide panels need thicker glass and heavier rollers.
Coastal exposure. More moving parts means more to corrode, so the finish choice narrows.

Where Stacking Windows Suit Best

Kitchen to patio openings. The classic use: a counter that becomes a serving hatch.
Wide openings onto a braai area. Most of the wall clears without a door sized threshold.
Rooms with a long view. Fewer frames in the view when open than a row of casements.
Where a swinging sash is impossible. Nothing projects into the space outside.
Entertainment areas. The opening is used as a pass through rather than as a window.

What Affects the Price

How many panels. Every extra panel is another track and another roller set.
The opening width. Wider spans need heavier sections to stay rigid.
Panel size. Big panels need thicker glass and stronger rollers.
The track detail. A flush threshold costs more and needs careful drainage.
The finish. Powder coating over natural, with coastal exposure narrowing the choice.
Whether the lintel is adequate. Enlarging an opening is building work quoted separately.

What to Include in Your Request

The address. Suburb and town.
The opening size. Width and height, measured at more than one point if the opening is old.
Which side it should stack. Left or right, seen from inside.
How many panels you want. Or say how much of the opening must clear.
What the sill is like. A counter, a sill or a flush threshold.
The finish you want. Natural, bronze, charcoal or a colour.

Before You Appoint a Window Fabricator

Ask how much of the opening clears. Stacked panels still take up width, and it is more than people expect.
Ask what the rollers are. They carry more weight here than on a two panel window.
Ask whether the track drains. A wide track across a patio opening collects water.
Ask about the lintel. A wide opening needs support above it, and that is not the window supplier.
Ask for the stacking side in writing. It cannot be changed after fabrication.
Ask about maintenance. Tracks on an outside wall need cleaning or they stiffen up.

Stacking Windows FAQs

How much do stacking windows cost in South Africa?

A three panel stacking window runs roughly R3,200 to R5,200 a square metre supplied and installed, and a four panel R3,800 to R6,200. A 2.4m by 1.2m three panel window commonly lands between R9,500 and R17,000 fitted. Panel count and panel size move it more than overall area does.

How much of the opening opens?

Less than people expect, because the stacked panels have to sit somewhere. On a three panel window you typically clear about two thirds of the width, and the stack takes up the remaining third. Ask for the clear opening width to be stated rather than the overall size.

What is the difference between a stacking window and a folding window?

A stacking window slides, with each panel on its own track, and the panels gather flat against one another. A folding window hinges, with panels concertinaed together, and it clears more of the opening but needs somewhere for the stack to swing. Stacking is the simpler and usually cheaper mechanism.

Can a stacking window span a very wide opening?

Up to a point. Beyond about four metres the sections get heavy, the track gets deep and the cost rises sharply, and at that size a folding or sliding door system is often the better purchase. Say the full opening width in the request and ask what the fabricator would recommend.

Do stacking windows leak?

The risk sits in the track, as with any slider, and a multi track window has more of it. Ask whether the track is drained and how, and whether the sill is set to fall outwards. On a patio opening this is the detail worth spending money on.

How long does it take?

Several weeks of lead time, as with any made to order frame. The install takes longer than a standard window because the tracks have to be set dead level over a wide span.

Stacking windows and stacking doors are often priced together, and Aluminium Windows South Africa collects quotes for both from the same installers.
