A large slim-line aluminium sliding door like no other.

German engineered, minimalist in design. Each of Cero by Solarlux glass panels can be up to 15 square meters, giving you unprecedented views and flooding your home with light.

Our ultra-slim sliding door combines the strength of aluminium with precision engineering to create a breath-taking functional piece of modern art from floor to ceiling.


Although each large-glass panel can be up to 15 square meters and weigh up to 1000kg, the intelligent technology ensures they move effortlessly. Together with a sightline of only 34mm, the slim aluminium profile ensures maximum view.

Enjoy your view in widescreen with concealed aluminium frames that fit perfectly into the floor, walls and ceiling. Whether you require large-scale fixed windows or moveable panels, Cero by Solarlux combines architecture, design and technology, like no other.

The panel frame is 72mm, with glass thickness of a maximum of 54mm. The surround frame is 91mm (for a single runner), 197mm (for a two runner) and 303mm for a three-runner.

Cero has two stand out technical features: ventilation of the glazing rebate and a unique carriage technology.

Designed for you

Design your door your way with our range of colours, styles and much more. Cero by Solarlux can be configured to be fixed, open-corner or sliding, so let your imagination and creativity free.

Sit back, relax and enjoy the view. Nothing is too much trouble with Cero. Each sliding door can be easily opened and closed thanks to the optional motorised control system.

There’s no need to worry about security either. Our triple glazed patio doors can be optionally certified to security class RC2 or RC3 / Secure by Design. Additionally, Cero can be equipped with special glass and can be integrated into an existing alarm system. The use of an intruder alarm sensor that activates when the glass breaks is also possible.

Cero: Absolute perfection

Cero combines beautiful aesthetics with flawless engineering. The triple track sliding door integrates glass rebate ventilation enabling the venting of the window edge and controlled drainage.

This design is the first to meet the statutory requirements for glass rebate ventilation and drainage. The stainless-steel rollers are integrated into the sash profile and protected from dirt by cleaning brushes. This lets the moveable panels stay soft and light.

Cero by Solarlux Performance

Cero achieves exceptional levels of thermal efficiency with class-leading Uw values as low as 0.79 (depending on chosen specification). Class 4 air impermeability.
