Residential ServicesAluminium Bifolding Doors

Open up your home with our range of bifolding doors, designed to let natural light flood your space. Creating a seamless connection between indoors and outdoors, the doors fold smoothly and quietly in a concertina style, stacking neatly to one side to provide uninterrupted views and enhance your property’s aesthetic.

Why Choose Aluminium Bifolding Doors for Your Home?

Bifolding doors open up to 90–95% of the doorway, creating a much wider and more seamless connection between indoor and outdoor spaces, perfect for gardens, patios, or entertaining areas.

Unlike sliding doors, which only partially open, bifolds can be fully stacked to the side, folding neatly away, keeping the space clear and unobstructed. Aluminium bifolding doors are especially versatile, with slim frames that suit both modern and traditional homes, offering a clean, open look with plenty of natural light and airflow.

Our Aluminium Bifolding Doors

Our bifolding doors can be fully bespoke, combining our high-quality glass with door frames from trusted brands such as Schüco and Cortizo.

Panels can be manufactured up to 1500 mm wide and 3000 mm high, tailored to your project and designed to meet the wind load requirements of the installation location.

Alistair Colins 5 ★

AGS handled everything from design to installation of our sliding doors. The team were friendly, tidy, and clearly knew their stuff. The finish is flawless and has totally transformed our kitchen extension

Chloe Brown 5 ★

Our architect recommended AGS and we’re so glad they did. The aluminium glazing is solid, smooth to operate, and beautifully finished. Professional, courteous installers and excellent aftercare – genuinely outstanding service

James Watson 5 ★

For our new-build project, we needed a reliable company to design, manufacture and install all the aluminium glazing. AGS took full ownership of the package, liaising with our architect and builder. Their technical knowledge, especially around thermal performance and detailing, was excellent. The finished product is stunning and functions perfectly

Paul Hopworth 5 ★

We’re absolutely delighted with the glazing supplied and fitted by AGS. From the first survey to final sign-off, communication was clear and responsive. They went the extra mile to resolve a last-minute design change without delaying the project. The doors operate beautifully, feel solid, and the overall finish is outstanding

Peter Guilbert 5 ★

We wanted something a bit special – big slim-framed sliders, a glazed roof and frameless balustrades. AGS talked us through Schuco and Cortizo options and gave sensible advice on budget. The end result is amazing; loads of light, everything feels really solid and the neighbours keep asking who did it
