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.
  • Seals – Weather sealing and internally glazed gaskets should make the doors completely draught-proof. Anti-finger trap gaskets increase safety.
  • 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.

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 Hertfordshire 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 Hertfordshire. Popular options include white, grey and black. Real woodgrain effects can be achieved using sublimation technology.
