Bi-fold vs French Doors: Which Is the Best Choice for Your Home?

Two of the most popular types of exterior doors found in homes across the country include bi-fold and French doors. They’re so popular that many homeowners struggle to choose one over the other when they’re looking to upgrade their entrances.

Green Doors knows a thing or two about both types, so we’ve written this guide to help you decide which one is the best choice for your home.

What Are Bi-fold Doors?

Bi-fold doors are made up of multiple glass panels with frames that fold in on each other. Rather than being obtrusive, the panels fold back completely to provide a seamless opening between indoor and outdoor spaces. 

How Do Bi-fold Doors Work?

Bi-fold doors fold and slide along a track, allowing multiple panels to concertina neatly to one or both sides of an opening. Each panel is connected by hinges, and they glide smoothly on runners, which creates a wide opening. When closed, bi-fold doors work like a standard wall of glass, offering security and insulation without compromising views. This design maximises natural light and air flow while seamlessly connecting indoor and outdoor areas.

Bi-fold doors can also feature what’s called a ‘traffic door’ – essentially an independent doorway from the rest of the panels, allowing users to open it without having to fold back the entire door.

Benefits of Bi-fold Doors

• Bi-fold doors allow plentiful natural light to enter your home
• They are lightweight and easy to position to specific openings
• Traffic doors for bi-folds are great for the colder seasons
• Maintenance is easy thanks to full access to the frame and glass
• Great for large openings thanks to the concentric design

Potential Drawbacks of Bi-fold Doors

• Bi-fold doors can be more expensive due to their complexity, and the more panels required will add to costs
• With all the mechanisms and components, it requires professional expertise to install bi-fold doors

What Are French Doors?

Derived from the casement door, French doors are popular traditional external and patio doors that feature a double-door configuration, and can open either inward or outward. French doors also feature large glass panes on each door to allow in lots of natural light.

How Do French Doors Work?

French doors work by opening outwards or inwards on side hinges, usually in a pair, to create a wide and accessible entryway. They feature large glass panes that allow natural light to flow through, even when closed.

This design combines practicality with style, offering easy access to gardens, patios or balconies while enhancing the sense of space indoors. When fitted with quality locks and seals, French doors also provide reliable security and insulation.

Benefits of French Doors

There are various benefits of French doors, including:

• A traditional design that’s suitable for every home, adding value, charm and enhancing kerb appeal
• Natural flowing light helps to reduce your energy bills
• A wide opening when both doors are open, great for transitioning between spaces and when moving furniture
• French doors provide good security thanks to strong locking mechanisms and secure glass

Potential Drawbacks of French Doors

• French doors take up more space when open, as they need to swing either inward or outward
• French doors feature a static design, meaning homeowners looking for something unique are better off with a different door type

Bi-fold vs French Doors: 6 Key Differences

1. Space & Layout Considerations

Bi-fold doors fold back neatly, making them ideal for creating wide, open transitions between indoors and outdoors – very suitable for both larger and more restricted spaces. French doors, on the other hand, open on hinges and require a clear swing space, which might not be the best option for compact layouts.

2. Aesthetic Appeal

French doors are timeless! Their elegant look suits period homes and classic design styles, but more modern finishes are available for contemporary spaces. Bi-fold doors provide a more modern feel with expansive glass panels that maximise views and natural light. The choice often depends on whether you want a traditional or sleek appearance.

3. Energy Efficiency & Insulation

The battle of bi-fold vs French doors comes to a draw in this regard. Both types can be highly energy efficient when fitted with quality glazing and seals. However, because bi-fold doors require multiple panels and careful installation, compared to French doors that have fewer joints, insulating bi-folds is slightly more challenging. 

4. Security Features

French doors rely on robust locks and multi-point systems for security, but their central opening can be compromised without reinforced frames. Bi-fold doors can incorporate multiple locking points along the track, offering strong protection when professionally installed.

5. Cost Comparison

The upfront cost of French doors is far cheaper and affordable, especially for standard-sized openings. Bi-fold doors will be on the more expensive side due to the more complex design, additional materials and mechanisms. But they still provide a worthwhile investment thanks to their long-term value of enhancing property appeal and usability.

6. Installation & Maintenance

French doors are simpler to install and generally require little maintenance. Bi-fold doors involve more complex fittings and moving parts, meaning hiring a professional for installation is strongly advised. Cleaning is easy thanks to having access to the different sections, but they may also require occasional adjustment to maintain smooth operation over time.

How to Choose Between Bi-fold and French Doors

Best for Small Spaces

French doors are often the most practical choice for homes with narrower wall openings, but also for spaces that can accommodate the swing opening. They provide easy access without needing structural adjustments, and their hinged design is simple to install, even in compact layouts. 

Best for Large Openings

Bi-fold doors are designed to maximise wide spans, making them perfect for open-plan living areas or properties that connect directly to gardens, patios or terraces. The multiple panels will fold back neatly, creating a near-seamless transition between your indoor and outdoor space.

Bi-fold doors are ideal for homeowners who want to extend their living space during warmer months and enjoy uninterrupted views all year round.

Best for Budget-Friendly Renovations

When considering your budget for home renovations, French doors are the more affordable choice, as their simpler design requires fewer materials and fewer fittings vs bi-fold doors. This affordability means you can achieve a stylish upgrade without stretching finances, especially if you are working with standard door sizes. Green Doors further supports homeowners’ budgets with pre-owned surplus mismeasured products. 

Best for a Classic Look

If timeless elegance is the goal, French doors are unmatched. Their symmetrical design, slim frames and traditional charm make them a favourite for period properties and homeowners who want to preserve a classic aesthetic. While bi-fold doors lean toward modern and contemporary homes, French doors complement more traditional architecture.

However, both door types are available in a variety of materials and colour finishes, meaning that just because French doors are considered classic, they can be altered to suit more contemporary spaces.
