Open Corner Sliding Doors

Open Corner Sliding Doors

Glass corner sliding doors can create open, frameless corners and are the epitome of the indoor-outdoor design trend.

KELLER minimal windows® can be easily designed to slide away from a meeting corner connection leaving no frame, or posts in its way.

An open corner to a room or space gives a feeling of extreme openness, allowing designers to effectively push back two entire walls for even greater access to the outside.

The open corner in KELLER minimal windows® is created with male and female connector joints that can be engineered to connect at nearly any angle required for your project.

When closed the square aluminium frame at the connection seals effectively for full weather protection.

A floating roof, seemingly defying the laws of gravity, coupled with the flush floor finishes of the minimal windows systems, can create a striking open appearance to even the smallest of extensions.

Innovative technology

An open corner detail can also work well on inverted corners, creating courtyard spaces with dynamic movement options from the internal areas to external areas. These are great for basement light wells or inner garden courtyards. These glass corner sliding doors can open on corners from 65 degrees to 177 degrees, as well as 90 degree corners. ‘Multi corner sliders’ are also possible with the minimal windows® system, this means that when the doors are slid open one elevation slides away from the building fabric, making sure that points of travel are possible across all tracks. Where a cantilevered roof or similar is being introduced to maximise on the open nature of the open corner sliding doors designers must keep in mind that these slim framed sliding glass doors can only take a live load deflection of +/-5mm. Why not mix a pocket door and open corner? The sliding glass doors can open away from a corner connection and then slide away into hidden cavity pockets within the walls for an invisible, disappearing sliding door.

Invisible Pocket Doors

Where a fully open aperture is required you can design any number of KELLER minimal windows® sliding glass doors to slide away into hidden pockets within a wall out of sight. When closed the sliding doors maintain their slim 21mm framing profile, providing uninterrupted, panoramic views of the outdoors. An excellent example of this is our Malbrook Road project, which utilises hidden pocket glass corner sliding doors in a modern rear extension. When open, the sliding panes are concealed within the building finishes, allowing the internal space to be merged with the outdoors. Find out more about Hidden Pocket Doors.

Juliette Balconies

Maintain minimal framing and large glass facades on upper floors with an invisible Juliette Balcony detail. A frameless glass balustrade can be invisibly integrated into the tracks of the KELLER minimal windows® sliding doors allowing doors to be opened on higher levels.

Modern Juliet balcony designs often utilise sliding doors as when open, they don’t take up any of the internal space. 

With this style of Juliet balcony, some are put off by the fact that they cannot have a completely open aperture, as often the sliding pane or panes stack onto a fixed one.

This issue can be resolved by using a pocket door where the sliding panes can ‘disappear into the walls leaving an open space that is roteecte by a glass balustrade.
