Bespoke bi-folding doors that open up an entire wall — slim sightlines, more light, and the strength and slim frames only aluminium delivers. Surveyed, made and fitted across London.
Built with trusted aluminium systems
Aluminium bi-fold doors fold neatly to one or both sides so you can open a whole wall to the garden, patio or street. They're the standout choice for extensions and open-plan homes, and for cafés, restaurants and shopfronts that want to bring the outside in on a warm day — then close down to a secure, weathertight, thermally efficient frontage.
We survey, supply and fit bespoke bi-folds to the exact size of your opening, framed in slim, strong aluminium and glazed to your spec. Everything is fitted to the manufacturer's standards and backed by our own 2-year parts & labour warranty — and we repair and service existing bi-folds too.
From a compact 2-panel opening to a 7-panel wall of glass, we configure the fold, stack and traffic door to suit how you actually use the space.
Any number of leaves to span your opening, stacking to one side or splitting to both. Widths up to full-wall spans.
Leaves fold internally or externally depending on your space and stacking preference.
A single "access" leaf that opens like a normal door for everyday use — without folding the whole set back.
Wrap two elevations around a corner with a post-free open corner for an uninterrupted view.
Choose a low threshold for near-flush, step-free access, or a weather-rated rebated threshold for exposed openings.
Bi-folds also work indoors — dividing spaces or closing off a room while keeping light flowing through.
One of our go-to systems is Smart's Visofold 1000 Slim — the UK's most popular aluminium bi-fold, now with sightlines reduced to 122 mm for an even larger glazed area. Kitemarked and PAS24-security tested, with a thermal break for genuine energy efficiency, and Made in Britain.
*Subject to site conditions. We also fit Cortizo and AluK bi-fold systems where a project calls for it.
Slim aluminium frames mean more glass and less frame — flooding the room with daylight and opening up the view.
Fold the panels right back to connect inside and out — perfect for entertaining, trading al-fresco or airy showrooms.
PAS24-tested multi-point and shoot-bolt locking — no leaf is a weak point, closed or folded.
Thermal-break frames and modern glazing achieve U-values from 1.5 W/m²K — matching quality double glazing.
Tested to BS 6375 for air, water and wind — dependable through a British winter.
Standard, dual-colour and textured finishes — powder-coated to last, inside and out.
Both are excellent — the right choice depends on how much you want to open up versus how much glass you want when closed. Here's the honest comparison.
