Bi-Fold Doors Supplied and Fitted

Open Up Your Home and Bring the Outside In

Bi-fold doors are an excellent way to create a brighter, more open and flexible living space.

Designed to fold neatly to one side, bi-fold doors can open up a much wider section of wall than a conventional door. This helps create a natural connection between your home and garden, making them particularly popular for kitchens, dining areas, extensions, conservatories and open-plan living spaces.

When closed, their large glazed panels allow natural light into your home and provide clear views of your outdoor space. When opened, the panels fold back neatly to create a wide and welcoming opening.

What Are Bi-Fold Doors?

Bi-fold doors are made from a series of glazed door panels connected by hinges. The panels slide along a track and fold together in sections, allowing them to stack neatly to one side or split in different directions depending on the chosen configuration.

A bi-fold doorset typically includes:

• Multiple glazed panels

• An outer frame

• Hinges and rollers

• An upper or lower track system

• Weather seals

• Locking mechanisms

• Handles and hardware

• Suitable threshold and drainage arrangement

The exact configuration can be tailored to the size of the opening and how you want the doors to operate. Depending on the chosen system, you may be able to select how many panels open to each side and whether one panel acts as a convenient everyday access door. Manufacturers offer a range of panel configurations for different property layouts and opening sizes.

Why Choose Bi-Fold Doors?

Create a Wider Opening

One of the biggest benefits of bi-fold doors is the amount of space they can open up.

Traditional French doors or patio doors leave part of the opening permanently covered by fixed frames or panels. Bi-fold doors fold back more compactly, helping create a wider connection between your indoor and outdoor spaces.

This makes them ideal for:

• Garden access

• Patios and decking areas

• Entertaining spaces

• Kitchen extensions

• Dining areas

• Conservatories

• Open-plan living rooms

Let More Natural Light Into Your Home

Large glazed panels can help brighten a room and make the space feel more open.

Even when the doors are closed, bi-fold doors provide broad views of the garden and allow more daylight into your home. This can be especially valuable in kitchens, rear extensions and family living areas where natural light and garden views make a noticeable difference.

Make the Most of Your Garden

Bi-fold doors can help your garden feel like a natural extension of your home.

During warmer weather, opening the doors creates a wide and inviting space for relaxing, entertaining and spending time with family. During colder months, you can still enjoy uninterrupted views of the garden while remaining warm and comfortable indoors.

Flexible Opening Options

Bi-fold doors can be designed to suit how you use your home.

Depending on the chosen product and layout, available options may include:

• Panels folding entirely to one side

• Panels splitting and folding in both directions

• Inward or outward opening

• An everyday traffic door for quick access

• Different numbers of panels

• Corner bi-fold configurations where suitable

The right option depends on the available space, the size of the opening and how you want to move between your home and garden.

What Are Bi-Fold Doors Made From?

Bi-fold doors are commonly available in aluminium, uPVC and timber. Each material has different advantages.

Aluminium Bi-Fold Doors

Aluminium is a popular choice for bi-fold doors because it combines strength with relatively slim frames.

Its strength-to-weight ratio allows manufacturers to create narrower sightlines while supporting larger glazed areas. This can help maximise views and natural light without making the doors feel bulky. Aluminium systems are also commonly available with powder-coated finishes in a wide range of colours.

Aluminium bi-fold doors are often chosen for:

• Modern extensions

• Contemporary homes

• Larger openings

• Homeowners wanting slim frames

• Premium garden-room upgrades

uPVC Bi-Fold Doors

uPVC bi-fold doors are generally a more cost-effective option.

They can provide good everyday insulation and low maintenance, although the frames are usually thicker than aluminium alternatives. They may suit smaller openings or customers looking for a practical solution at a lower price point.

Timber Bi-Fold Doors

Timber bi-fold doors offer a warm and traditional appearance.

They can be particularly attractive in period homes or properties where natural materials are preferred. However, timber usually requires more routine care and maintenance than aluminium or uPVC to keep it protected from the weather.

Energy Efficiency and Thermal Performance

Modern bi-fold doors can provide strong thermal performance when properly specified and fitted.

The thermal efficiency of a doorset is measured using its U-value. The lower the U-value, the less heat passes through the complete doorset. It is important to compare the U-value of the whole product rather than only the centre pane of glass, because the complete frame, glazing and seals all affect performance.

A quality bi-fold door system may include:

• Thermally broken aluminium frames (Insulation barrier)

• Insulated profile sections

• Double or triple glazing options

• Low-emissivity glass

• Effective compression seals

• Suitable threshold drainage

• Warm-edge spacer bars

England’s Approved Document L sets energy-performance standards for windows and doors in new and existing buildings.

Ask us about the U-values achieved by our selected bi-fold doors.

A window or door's U-value measures the rate at which heat transfers through it. Measured in W/m²K (Watts per square metre Kelvin). Lower values indicate better thermal performance.

Secure Bi-Fold Doors

A large glazed opening should still provide confidence and peace of mind.

Modern bi-fold doors can be highly secure when supplied with a strong frame, suitable glazing and a well-designed locking system. Security features may include:

• Multi-point locking

• Anti-snap, anti-pick or anti-drill cylinders

• Robust hinges

• Anti-lift track protection

• Internal glazing beads

• Toughened or laminated safety glass

• Secure handles and hardware

High-quality aluminium bi-fold doors are commonly designed with multi-point locks, strong hinges and track-security measures. Some product ranges are available with PAS 24 testing and Secured by Design accreditation. PAS 24:2022-certified sliding-folding doorsets are listed within the Secured by Design product database.
