Aluminium Folding & Stacking Doors for South African Homes

Few door systems change a living space as dramatically as a folding door.

When closed, the large glazed panels allow natural light into the room and maintain a visual connection with the patio, garden or entertainment area. When opened, the panels fold and stack towards the side, turning two separate spaces into a much larger connected area.

This makes aluminium folding and stacking doors particularly suited to modern South African homes where patios, braai areas, covered entertainment spaces and gardens form an important part of everyday living.

They can be used for:

• Patios and covered verandas
• Entertainment and braai areas
• Lounges and family rooms
• Dining areas
• Pool-facing rooms
• Large kitchen openings
• Restaurants and hospitality spaces
• Offices and commercial buildings

Aluminium also provides a slim, contemporary appearance while remaining practical for exterior applications and relatively easy to maintain.

How Aluminium Stacking Doors Work

An aluminium stacking door consists of several glazed aluminium panels connected to operate as one folding system.

Instead of one panel simply sliding behind another, the panels move along the track, fold at their connecting points and stack together towards the side of the opening.

The result is the feature that makes this system so popular: a much larger portion of the opening can be opened.

The Vistafold system used for Sigmadoors folding doors combines aluminium frames, hinges, guides, rollers, tracks, seals, handles and locking hardware to create a coordinated folding action.

Depending on the required configuration, the panels can be arranged to suit the direction in which the opening needs to operate.

Are Folding Doors and Stacking Doors the Same?

For the Sigmadoors Vistafold range, aluminium folding doors and aluminium stacking doors refer to the same type of door system.

Different customers use different names, including:

• Folding doors — describes how the panels fold together.
• Stacking doors / stacker doors — describes how the folded panels stack together at the side.
• Bi-fold doors — another commonly used description for folding panel doors.
• Folding stacking doors — combines both descriptions.

Whatever name you use, the important consideration is the actual operating system, panel configuration, opening size and specification of the door.

Aluminium Folding Door Sizes

Choosing the correct folding door starts with the opening.

Sigmadoors offers a broad range of standard sizes, making it possible to select a door according to both the width and height of the opening.

Standard heights in the range include:

2100mm High Folding Doors

A practical height for many standard residential openings, patios and entertainment areas.

2400mm High Folding Doors

The additional height creates taller glazing and works particularly well in contemporary homes with higher ceilings and larger openings.

2700mm High Folding Doors

For selected configurations, 2700mm-high folding doors create a more dramatic floor-to-ceiling effect and are particularly suited to larger architectural spaces.

The correct door should always be selected according to the required structural opening and installation requirements rather than simply ordering from an approximate measurement.

Important: Product dimensions shown by Sigmadoors are nominal opening sizes. Check the individual product specification and required installation clearance before preparing or altering an opening.

3, 5 & 7 Panel Aluminium Folding Doors

The number of panels has a major influence on how a folding door looks, operates and fits the available opening.

3 Panel Aluminium Folding Doors

A 3-panel folding door is a good solution for smaller and medium-sized openings where you want the benefits of a stacking system without requiring a very wide wall opening.

Sigmadoors offers 3-panel configurations across several widths and heights, making these doors suitable for patios, dining areas, smaller entertainment spaces and residential extensions.

5 Panel Aluminium Folding Doors

5-panel aluminium folding doors are particularly well suited to medium and large openings.

The additional panels allow wider openings to be divided into manageable glazed sections while still providing the folding-and-stacking action that makes this system attractive for entertainment areas.

They work especially well between a lounge or family room and a covered patio, braai area, garden or pool terrace.

7 Panel Aluminium Folding Doors

For very wide openings, 7-panel stacking doors provide an impressive architectural solution.

They are particularly suited to large entertainment spaces and contemporary homes where the intention is to open a substantial section of the wall and create a strong connection between the interior and exterior.

Sigmadoors' standard range includes 7-panel folding doors in widths extending beyond 6 metres, depending on the selected height and configuration.

Aluminium Folding & Stacking Door Prices

The price of an aluminium folding door depends largely on its size, number of panels, height, finish, glazing and configuration.

As a general rule, a wider door with more panels requires more aluminium, glass, hardware and operating components than a smaller 3-panel system.

Sigmadoors displays prices directly on its standard folding-door products so you can compare options before ordering.

When comparing aluminium stacking door prices, consider:

• Door width and height — larger doors require more aluminium and glass.
• Number of panels — 3, 5 and 7-panel configurations use different quantities of framing and hardware.
• Frame finish — the selected aluminium colour or finish can affect the final price.
• Glass specification — different safety, privacy and solar-control glazing options may change the cost.
• Standard or custom size — standard catalogue sizes can be purchased directly, while custom doors are quoted according to specification.
• Supply or installation — installation requirements depend on the project and site conditions.

Vistafold Aluminium Folding Door System

Sigmadoors folding and stacking doors are based on the Vistafold aluminium folding-door system.

The system is designed for large glazed openings where multiple door panels need to move together smoothly and stack compactly towards the side.

The door incorporates the components required for coordinated operation, including tracks, rollers or guides, hinges, locking hardware and weather seals.

A correctly specified and installed Vistafold door can provide a practical combination of:

• Large glazed areas
• Wide opening capability
• Smooth folding operation
• Compact panel stacking
• Indoor-outdoor connection
• Weather protection when closed
• Contemporary aluminium framing
• Residential and commercial versatility

Because a folding door contains several interconnected moving panels, accurate manufacture and installation are particularly important. The frame needs to be level, square and correctly supported for the panels and hardware to operate as intended.

Glass Options for Aluminium Folding Doors

Large folding doors contain substantial areas of glass, making the glazing specification an important part of the complete door.

Sigmadoors folding doors are supplied with safety glazing, with other glass options available depending on the product and project requirements.

• Clear Glass — a good choice when maximum visibility and natural light are the priorities.
• Arctic Snow / Obscure Glass — provides additional privacy while still allowing diffused natural light through the opening.
• 6.38mm Laminated Safety Glass — glass layers bonded by an interlayer so broken fragments tend to remain attached rather than separating into loose pieces.
• S10 Bronze — adds a warmer tinted appearance to the glazing.
• S10 Grey — creates a neutral darker tint suited to many charcoal and black aluminium installations.
• S10 Silver — provides a more reflective appearance where that aesthetic is preferred.

The appropriate glass should be selected according to the location of the door, safety requirements, privacy, exposure and the desired architectural appearance.

Aluminium Folding Door Colours

Your frame colour has a major influence on how the finished stacking door relates to the rest of the building.

Sigmadoors aluminium windows and doors are available in popular finishes including:

• Natural Anodized (Silver) — a classic aluminium finish with a clean metallic appearance.
• White — works particularly well with light façades and traditional or contemporary architecture.
• Bronze — a warm, established aluminium finish suited to many residential properties.
• Charcoal — one of the most versatile choices for contemporary South African homes.
• Black — creates a strong architectural contrast and works particularly well with modern glazing.

For a coordinated result, folding-door frames can be matched with the aluminium windows and other doors used throughout the property.

Where Do Aluminium Stacking Doors Work Best?

Stacking doors make the most sense where opening up the space is more important than simply providing access through a doorway.

A large lounge facing a patio is a good example. A conventional door provides an entrance and exit; a folding stacking door can transform much of the wall into an opening.

This makes the system particularly effective for patios, entertainment areas, braai rooms, pool areas and large living spaces.

They can also work well in restaurants, offices and commercial spaces where flexible separation between areas is useful.

For a smaller opening where maximum opening width is not essential, a conventional hinged or sliding door may offer a simpler solution.

Aluminium Folding Doors vs Sliding Doors

Both systems work well for patios and large glazed openings, but they operate differently.

Feature	Folding / Stacking Doors	Sliding Doors
Operation	Panels fold and stack	Panels slide horizontally
Opening	Can open most of the aperture	Some panels generally remain in the opening
Number of panels	Multiple connected panels	Sliding and fixed panels
Best feature	Maximum indoor-outdoor opening	Simple everyday operation
Typical use	Patios and entertainment spaces	Patios, lounges and general access
Visual appearance	More vertical panel divisions	Larger individual glass panes
Wide openings	Excellent	Excellent with the correct system

If your main priority is creating the widest possible connection between two spaces, a folding or stacking door is often worth considering.

If you prefer fewer panel divisions and straightforward sliding operation, an aluminium sliding door may be more suitable.

Standard vs Custom Aluminium Stacking Doors

Standard Folding Doors

Choosing from the Sigmadoors standard range gives you access to established combinations of widths, heights and panel configurations.

Because the category includes numerous standard products, it is often possible to find a door that closely matches the requirements of a new build or renovation.

Custom Folding Doors

Not every architectural opening fits a catalogue size.

Sigmadoors can manufacture custom aluminium folding and stacking doors for projects requiring different dimensions or configurations.

A custom quotation can take into account:

• Opening width
• Opening height
• Number of panels
• Panel configuration
• Opening direction
• Aluminium colour
• Glass specification
• Project requirements

For new construction, it is preferable to coordinate the door dimensions with the architectural drawings and building opening before construction reaches the final opening stage.

Aluminium Folding Door Supply & Installation

Sigmadoors supplies aluminium folding and stacking doors for new homes, renovations, extensions, developments and commercial projects.

Professional installation is also available for projects in Johannesburg, Sandton, Randburg, Fourways, Midrand, Centurion, Pretoria, the East Rand and surrounding Gauteng areas.

Correct installation is especially important with a multi-panel folding system. The opening and frame need to be correctly aligned so that the individual panels can fold, move and lock properly.

For custom or installed doors, send Sigmadoors the opening dimensions, photographs, door schedule or architectural drawings where available. This makes it easier to determine the appropriate size and configuration.

Frequently Asked Questions About Aluminium Folding & Stacking Doors

Are aluminium folding doors and aluminium stacking doors the same?

For the Sigmadoors Vistafold range, the terms generally refer to the same door system. The panels move along the track, fold together and stack towards the side of the opening. They are also sometimes called stacker, bi-fold or folding stacking doors.

How much do aluminium stacking doors cost?

Prices vary according to width, height, number of panels, frame finish, glazing and whether the door is a standard or custom size. Sigmadoors displays current prices on its standard folding-door products, making it possible to compare different configurations online.

What sizes do aluminium folding doors come in?

Sigmadoors offers numerous standard widths across 3, 5 and 7-panel configurations, with common heights including 2100mm, 2400mm and selected 2700mm options. Custom sizes can also be quoted.

Should I choose a 3, 5 or 7-panel folding door?

The appropriate number of panels depends primarily on the width of the opening, required configuration and how you want the panels to operate. Three-panel doors suit smaller openings, while 5 and 7-panel systems allow increasingly wider openings.

Can stacking doors be custom made?

Yes. Custom folding and stacking doors can be manufactured where a standard catalogue size is unsuitable. Provide the required opening dimensions and project information for quotation.

What glass is used in aluminium folding doors?

Safety glazing should be used where required for doors. Sigmadoors' folding-door range includes safety glass, with different glazing options available depending on the required appearance, privacy and performance.

Are stacking doors suitable for patios?

Yes. Patios and entertainment areas are among the most popular applications because the panels can be folded and stacked aside to create a large connection between the interior and exterior.

Can I use stacking doors for an entertainment or braai area?

Yes. They are particularly useful for entertainment and braai areas because the space can remain enclosed when necessary and then be opened substantially when entertaining.

What is the difference between a stacking door and a sliding door?

A conventional sliding door moves panels horizontally along tracks, with part of the opening generally remaining occupied by one or more panels. A folding stacking door folds multiple connected panels together and stacks them towards the side, allowing more of the opening to be cleared.

Does Sigmadoors install aluminium folding doors?

Sigmadoors offers aluminium door supply and installation services in Johannesburg, Pretoria and surrounding Gauteng areas. Installation requirements and availability should be confirmed when requesting your quotation.
