Frequently Asked Questions
Bifold doors consist of multiple panels that fold and slide neatly to one side, creating a wide opening that seamlessly connects indoor and outdoor spaces. They are ideal for patios, extensions, or open plan living.
Aluminium bifold doors are a top choice for modern home design — combining style, flexibility, and performance. Key advantages include:
When it comes to connecting your home and garden, both aluminium bifold doors and sliding doors offer modern style and performance, each has its own strengths depending on your priorities:
| Feature | Aluminium Bifold Doors | Aluminium Sliding Doors |
|---|---|---|
| Opening Style | Fully folds back to open the entire width | Panels slide behind each other for partial opening |
| Maximum Clear Opening | Full-width access when stacked | Limited by fixed panes or overlapping panels |
| Intermediate Sightlines | 110mm | 20mm, 25mm or 35mm depending on system |
| Space Required | Needs space to fold panels internally or externally | No swing clearance needed — great for tight spaces |
| Aesthetics | Creates a striking, concertina-style feature | Seamless, minimalist look with large glass expanses |
| Ideal For | Entertaining, open-plan layouts, garden access | Wide views, modern architecture |
| Operation | Hinged fold-and-slide motion | Glides smoothly along tracks |
If you're looking for a wide, fully open aperture and maximum flexibility, bifold doors are an excellent choice, while sliding doors are ideal for those who prefer uninterrupted views, larger panes of glass, and a sleek, space-saving finish.
A traffic door is a single operable panel within a bifold door system that functions like a standard hinged door. It allows for everyday access in and out of your home without needing to fold back the entire set of panels — perfect for convenience and quick entry & exits.
Traffic doors are typically included in configurations with an odd number of panels (e.g. 3, 5, 7). Bifold layouts that open in even-numbered pairs (such as 2-2-0, 4-4-0, 6-6-0) do not include a traffic door, as the panels operate in symmetrical sets.
The price of aluminium bifold doors can vary depending on several factors, including:
