How do I choose the right bifold doors for my home?

Bifold doors are glazed door systems with panels that turn 90° and 'stack' neatly to the side when opened. Typically used in garden-facing rooms and open-plan living spaces, bifold doors are a popular alternative to sliding glass doors because they create a wider opening and a seamless transition to outside.

For everyday access, bifold systems may include a traffic door – a single panel that swings open like a regular door without the need to open up the whole wall. When closed, bifold doors provide large spans of glazing, with each panel measuring up to 1m wide, maximising natural light and providing views to the outside.

When choosing a bifold door, start by considering the space where it will be installed and how you want it to look and function once complete.

Bifold doors are often installed as part of a home extension, giving layout and design flexibility. They can also be tailored to suit an existing home, with bespoke options to achieve your aesthetic vision. In either case, think about:

• How big is the opening? – The size will determine the number of panels required, as well as their height, width and weight.
• Are there corners? – Bifold doors can be installed at corners without a corner post, creating a truly open-plan feel. However, additional structural support may be required.
• What size should each panel be? – Wide panels reduce the number of vertical sightlines when the doors are closed. However, larger panels are heavier, which can affect handling. When the panels are bigger, the stack of opened panels may also be more awkward.
• Should the doors open inward or outward? – Most bifold systems open outward, so the stacked panels do not occupy valuable indoor space. Inward-opening configurations are possible but will require careful consideration of furniture placement and how the stack may obstruct movement.
• Where will the opened panels be stacked? – The stack should be positioned so it doesn’t block walkways.  Panels can stack to one side of the opening or split to both sides, depending on what’s best for your space.
• What will the threshold look like? Bifold doors may have a raised threshold that requires stepping over or have a fully flush threshold that is level with the floor. A flush threshold creates a clean, uninterrupted flow between inside and out, while also reducing trip hazards and improving accessibility.

Justin Spires, technical lead at Solarlux, explains that bifold doors don’t have to be complicated. As long as they are designed, manufactured and installed to a high standard, they will be a beautiful, reliable feature of your home. “At their core, bifold doors are a simple concept. When they’re designed and installed properly, they completely transform a space. Solarlux precision engineering and bespoke configuration mean the doors can be tailored to suit any home.”

If this seems like a lot to think about, the Solarlux design team can guide you through every step, helping to create a bifold door that fits your space perfectly and delivers the look and performance you want.

Bifold doors combine glazing and framing profiles. The choice of glazing will depend on strength and wind resistance, as well as security, thermal performance and solar gain. The team at Solarlux can help you determine the right type of glazing for your project.

Although bifold doors are predominantly made of glass, the frames have a huge impact on appearance and performance. Solarlux bifold doors can be supplied with timber, aluminium or timber-aluminium composite frames.

• Timber provides natural beauty, warmth and a more traditional appearance
• Aluminium offers strength, slim profiles and a modern aesthetic. Available in 30 RAL colour options to match the building’s exterior, it can easily blend in with existing window frames and doors.
• Composite construction allows you to enjoy the benefits of both. It can also be used to create different interior and exterior appearances.

The choice of frame material also affects performance, longevity and maintenance. Aluminium, for example, requires cleaning to prevent corrosion, while timber needs occasional refinishing to maintain its appearance and durability.

When choosing bifold doors, small details can make a big difference. Thoughtful design ensures that the doors are visually stunning and easy to use with minimal maintenance.

• Low or flush thresholds provide a seamless transition between indoors and outdoors, reducing trip hazards and ensuring easy access for all users.
• Durable stainless-steel rollers and precision-engineered tracks ensure the panels glide smoothly.
• Accessible running gear makes cleaning and maintenance straightforward, helping to ensure long-term performance and aesthetics.
• Manual or powered operation are available. The choice will depend on the size of your bifold doors and your personal preference. Remote control options are also available.
• Optional integrated LED track lighting highlights the architecture and enhances outdoor ambience.

Features and benefits

To ensure your bifold doors are perfect for your home, practical considerations such as performance, operation, functionality and maintenance are just as important as aesthetics. Here’s a quick list of questions to help you find the right glazing system for your home:

• What width and height should each panel be?
• Where should the panels stack when opened?
• How narrow should the sightlines be?
• Do you want timber, aluminium or composite frames?
• What colour and finish should the frame have?
• How are the doors and their tracks cleaned and maintained?
• What are the local weather conditions – wind, sun exposure or coastal salt air?
• How will glare and overheating be managed – including integrated blinds or shading options?
• Do the doors need to exceed standard security, thermal or acoustic performance criteria?
• Do you need a traffic door for everyday access? Where should it be positioned?
• Should the doors be manually operated or automated?

Whether you’re refreshing an existing space or planning a major renovation, the right bifold doors can change how you live – bringing light, openness and connection with the outdoors.
