The benefits of cero

hoher glasanteil

Maximum transparency

Its slender frame and profiles help to make the elements as transparent as possible. The sight lines are kept to just 34 mm, resulting in a symmetrical and minimalist design that is underlined by the 98% glass composition. Depending on which model you choose, your cero will come with either triple or double-toughened single-pane safety glass (TSG). 

Large panel sizes

Even with a glass area of 15 m² and a weight of up to 1000 kg per panel, our extra-large cero sliding window can still be opened and closed with no problem at all. Stainless steel carriages and rails guarantee light and low-wear sliding, the integrated stainless steel track rollers ensure even load distribution. Electric panel drive is also possible if required. cero successfully passed a durability test of 100,000 opening and closing processes.

Motorisation und group operation

The sliding panels can be fitted with a fully automated operating system including electro-mechanical locking and unlocking, which offers the user interdependent control of several panels via a control unit.


cero has been tested and certified in line with the highest security standards, and equipment that meets anti-burglary protection classes RC2, and RC3 is available as an option. A 2-point locking rod with adjustable locking points and a 24 mm latch bolt in the top running track and guide rail are fitted as standard. Connections to alarm systems, a lock monitoring system, and notification systems such as broken glass sensors and position monitoring systems are all available as options.
