Bi-fold doors

Open up your home and fill it with natural light 

Combining the refined, architectural look of aluminium and the latest thermal and security technology, leaving you with beautifully balanced bi-folding doors. Bi-folding doors should maximise the light flooding into your home, and the enjoyment of your garden or patio. Bringing an improved sense of space and creating panoramic views that can transform interiors. They also need to offer reliable operation, while keeping heating bills low, and would-be intruders out. That is why we have designed our Prestige bi-folds to offer you the perfect balance of refined looks, exceptional thermal performance and outstanding operation.

Bring the outside in 

Elitis bi-folds can help soften boundaries, creating an increased sense of space and a seamless transition between your garden and the inside of your home. 
Slim, equal 138mm sash-to-sash sightlines ensure light bathes your interiors, even when your doors are closed. Giving you bright airy interiors no matter what style or configuration you choose.

Quality components for flawless operation 

Every element of the Prestige bi-fold has been engineered to operate perfectly. One-piece stainless steel tracks in the head and threshold ensure smooth and reliable rolling of the sashes, while hinges rated to 120kg help keep every sash perfectly aligned during operation. No aspect of the door has been overlooked  and we even use unique tri-material gaskets that feature a low-friction coating for smooth performance and reliable sealing. 

Multi point locking

Outstanding security features

Security features are built into every bi-fold, keeping you and your home safe. From bespoke Winkhaus Thunderbolt locks, to custom-designed VBH hardware, every element of the Prestige bi-fold has been designed to keep you and your home secure. All our lock options, including our high security Ultion lock upgrade – offer anti-snap, anti-bump and anti-pick protection while our patented corner jointing method creates exceptionally strong frames, maximising the inherent strength of Sheerline’s aluminium construction.
