For anyone who wants more than just a sliding window

cero opens rooms with extensive glass panels: Impressive transparency dissolves the boundary between inside and outside. cero offers every possibility required from architecturally demanding buildings from a constructive and creative point of view. Its slender frames 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. And there is also another important feature: The extremely large glass areas of up to 15 m² emphasise the focus on quality and security aspects in the design. 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.

Maximum transparency for a wide range of projects

The benefits at a glance

An impressive project in Offenbach: the Molenpark loft house. The desire for as much transparency as possible was fulfilled by the cero sliding windows. You can see the installation of the glass elements, which are several square metres in size, in the video.
