Aluminium Bifold vs French Doors: Which Suits Your Home?
Bifold or French doors for your extension? Compare opening width, glass area, cost and style to choose the right aluminium doors for your UK home.
Both bifold and French doors open your home to the garden, but they do it in very different ways. If you are choosing between them for an extension or renovation, here is a clear comparison to help you decide.
How each one works
Bifold doors are made of several panels hinged together that concertina and fold back to one or both sides, stacking neatly out of the way. They can open up almost an entire wall. French doors are a classic pair of doors, hinged at the outer edges, that open in the middle like a double door. They are simpler, with just two leaves.
Opening width and flow
This is the big difference. Bifolds can span a very wide opening and fold almost completely away, giving a near uninterrupted connection between inside and out. French doors open a fixed, narrower gap, the width of the two leaves. If your goal is to throw the whole wall open on a summer day, bifolds win. If you want a neat, everyday opening onto a patio or balcony, French doors do the job elegantly.
Glass and views when closed
When closed, bifolds have a frame at each panel join, so there are a few more vertical lines across the glass. French doors have fewer frames, just the central meeting point and the outer frame, giving a slightly cleaner view for a smaller opening. For the largest glass areas overall, though, a wide bifold or a sliding door usually delivers more.
Cost
French doors are generally the more affordable option, because they have fewer panels, less hardware and a simpler mechanism. Bifolds cost more, reflecting the multiple panels, hinges and running gear, and the much wider opening they provide. Your budget and the opening size will often point you to one or the other.
Space and practicality
Bifolds need somewhere for the panels to stack, either inside or outside the opening, so allow for that. French doors swing open on hinges, so you need clearance for the leaves to open into or out of the room. For everyday use, French doors are quick to pop open, while bifolds are ideal when you want to open everything up.
Which should you choose?
Choose bifolds if you have a wide opening and want to connect the whole room to the garden with a dramatic, fully opening wall of glass. Choose French doors if you have a narrower opening, want a classic look, everyday convenience and a lower cost. For very wide openings where you also want big uninterrupted glass, also consider sliding doors.
