Yes, aluminium bifold doors are a good choice if you want slim frames, wide glass areas and a long service life. Aluminium is strong enough to carry large, heavy glazed leaves, and suppliers quote 30 years or more with maintenance. They cost more than PVCu and need a properly supported opening.
What makes aluminium suit bifold doors?
- Strength allows slim sightlines, with some systems quoting frames as narrow as around 36 mm.
- Powder-coated finishes come in a wide range of RAL colours.
- Aluminium resists rot and warping, and expands less than plastic with temperature changes.
- Modern frames include a thermal break, a non-conductive barrier between the inner and outer profiles.
How long do aluminium bifold doors last?
Manufacturers quote 30 years or more for the frame with regular care. Treat that as a supplier claim, not a guarantee. Hinges, rollers, tracks and seals are wear parts and usually need cleaning, adjustment or replacement well before the frame does.
What should you check before choosing one?
- The thermal break and glazing specification, which decide how warm the doors feel.
- The threshold and drainage detail, so rain does not collect in the track.
- The structure above the opening: wide, heavy doors need a correctly rated lintel.
- Whether Building Regulations apply, which they usually do if the opening is being widened.
