Why Choose Aluminium Bifold Doors?

There are many reasons that both homeowners and installers in London love aluminium bifold doors:

Maximal Views and Natural Light

The large glazed areas and slim aluminium frames of bi-fold doors provide stunning views and let daylight flood into your home. By opening up entire walls with bifold doors you can fully appreciate your garden, patio or balcony.

Indoor/Outdoor Living

When open, bifold door panels stack neatly to the side allowing easy access and creating a wide unobstructed opening. This allows you to freely move between interior and exterior spaces for a more seamless lifestyle.

Space Saving

Unlike traditional French or patio doors, bifold door panels fold back in a concertina style without projecting out into a room. This makes them perfect for smaller spaces where you want to maximise usable floor area.

Security and Sound Insulation

Quality bifold doors use robust locking mechanisms and multi-point locks for security. Thermal and acoustic insulation minimises outside noise.

Durability and Low Maintenance

Bifold doors made from aluminium are highly durable and weather-resistant. The powder-coated finish is guaranteed for 20 years and requires little maintenance beyond occasional cleaning.

Choosing the Right Aluminium Bifold Doors

There are a few key considerations when selecting aluminium bifold doors for a project:

  • Performance – Check that the doors meet thermal and acoustic insulation standards and are certified by independent organisations like the British Standards Institute (BSI).
  • Hardware – Doors should glide open effortlessly on a smooth roller track system. High-quality hardware is essential for reliable operation over time.

  • Security – Multi-point locks that meet PAS 24 standards provide the highest levels of security and resistance to forced entry.
  • Credentials – Reputable bifold door brands will provide extensive product guarantees. Also, look for industry accreditation like ISO 9001 certification.
  • Experience – An experienced manufacturer is invaluable for creating bespoke bifold doors to match your exact specifications. They will also have the technical abilities to fulfil challenging designs.

How much do aluminium bifold doors cost?

As a bespoke product, aluminium bifold door prices vary depending on the complexity of the design, the number of panels, accessories are chosen and other custom specifications

What are the best brands of aluminium bifold doors?

Some of the best brands available in the UK include Schuco, Smart Systems, Origin and AluK. Always check that bifold doors are certified by independent organisations like BSI. Many quality manufacturers will also back their bifold doors with guarantees of up to 20 years.

How energy efficient are aluminium bifold doors?

The latest models of thermally broken aluminium bifold doors easily achieve u-values between 1.4 and 1.8 W/m2K. This allows them to exceed the insulation requirements of UK building regulations. All glass should be high-performance double or triple glazing.

How secure are aluminium bifold doors?

Aluminium bifold doors use multi-point locking mechanisms and shootbolt locks for enhanced security. Choose bifold doors certified to PAS 24 standards for the highest levels of security and resistance to forced entry. Internally glazed beads also prevent the glass from being removed from outside.

Should bifold doors open in or out?

Most homeowners prefer bifold doors that open outwards as this helps maximise interior floor space when the doors are retracted open. Outward-opening bifold doors also have enhanced weather performance as water can run off the external face of the doors. However, both inward and outward-opening bifold doors are available.

Bifold Door Designs and Configurations

One of the best things about aluminium bifold doors is the high degree of customisation possible. At Aston Architectural Aluminium we offer London installers a bespoke bifold door service and have the manufacturing capabilities to fulfil virtually any order.

Number of Door Panels

The number of door panels ranges from 2 to 6 or more. More panels mean a wider opening space when fully retracted. An even number of panels is most common.

Opening Options

Bifold doors are available as inward or outward openings. Outward opening helps maximise interior space.

Door Operation

Doors can be designed to open from the left, right or both sides to suit your space. With double-action bifold doors, panels can open inwards and outwards for flexibility.

Height and Width

There is no set size for bifold doors. They can be designed to fit openings as small as 1.5 metres up to unrestricted spans over 6 metres wide. Panels can be manufactured up to 2.5 metres in height.


Over 200 RAL colours are available for aluminium bifold doors in London. Popular options include white, grey and black. Real woodgrain effects can be achieved using sublimation technology.
