Aluminium vs composite bifold doors

David Ross Sales Manager

Author: David Ross - Sales Manager

Aluminium and composite are both popular materials for bifold doors, both offering a reliable and durable option. However, there are a few differences between each to be aware of before you purchase a bifold door.

Here, we provide a complete guide to aluminium vs composite bifold doors, exploring the key benefits of each and factors such as appearance and cost.

What are composite bifold doors, and how are they made?

Composite bifold doors are often made from a combination of timber and aluminium.

There are three ways to construct external composite bifold doors:

  • Use a timber frame and add an external aluminium cladding (known as aluminium clad-timber)
  • Start with an aluminium bifold frame and add wooden strips on the side facing the interior (known as timber clad-aluminium)
  • Timber and aluminium sandwiched around a foam core.

Aluminium-clad timber offer a number of superior specifications, including thermal insulation, as wood is a better insulator than aluminium. They also provide excellent noise reduction, as a solid timber frame will cut out more sound than aluminium. This makes aluminium-clad bifold doors the best choice for those living in noisy areas. If the frame is combined with triple-glazed glass, this also improves noise reduction.

  • Thermal insulation — Wood is a better insulator than aluminium
  • Noise reduction — A solid timber frame will cut out more sound than aluminium. This makes aluminium-clad bifold doors the best choice for those living near train tracks or under flight paths, especially when the frame is combined with triple glazed glass.
