Aluminium Bifolding Doors

Bifold doors are one of the most transformative products we install. Done right, they fundamentally change how a space feels — flooding it with light, removing the barrier between inside and outside, and opening up 90% or more of the wall when fully folded.

Aluminium is almost always the right choice for bifolds. The slimmer sightlines mean significantly more glass for the same opening — and that matters when you're making a statement about light and space. Our aluminium bifolds feature thermally broken profiles that match uPVC for energy performance while maintaining the elegant slim frame.

The sweet spot for bifolds is a rear opening of 2.4m or wider connecting a living space to a garden, patio or terrace. For narrower openings, a wide single door or French door may actually serve you better — and we'll always advise honestly.

What to Consider

Getting Bifolds Right

How many panels do I need?

For a 3.6m opening, 3 panels work well. For 4.8m or more, 4–6 panels give a cleaner result. We'll advise the right configuration for your opening during the free survey.

Which direction should the doors fold?

Consider where your traffic door is — the panel that opens independently without folding the whole set. This affects daily usability far more than most people anticipate at the buying stage.

What about the floor level?

A low-profile threshold (under 15mm) creates a near-flush transition — essential for both aesthetics and accessibility. We always aim for the lowest possible threshold in our installations.

Do bifolds need planning permission?

Generally no for replacing an existing opening. Creating a new opening in an external wall may require building regulations approval. We'll advise during your survey.
