Aluminium vs uPVC Bifold Doors
Choosing the right material is the most important decision when buying bifold doors. Here's everything you need to know to make the right choice for your Surrey home.
Aluminium Bifold Doors
The Premium Choice · £2,800 – £8,500+ installed
Aluminium is the gold standard for bifold doors. Its exceptional strength-to-weight ratio allows for dramatically slimmer frames — meaning more glass, more light, and a cleaner aesthetic. Thermally broken aluminium profiles deliver outstanding energy performance without compromising on looks.
Advantages
- Dramatically slimmer frames — up to 45mm sightlines
- Powder-coated in any RAL colour, inside and out
- Thermally broken for A-rated energy performance
- Stronger than uPVC — spans wider openings
- Will not warp, bow, or discolour over time
- Recyclable — environmentally responsible choice
- Suits contemporary and traditional homes equally
Considerations
- Higher initial investment than uPVC
- Slightly longer lead time for bespoke colours
