The stunning bespoke thermally insulated aluminium profile system cero sliding door benefits from 40 years of Solarlux experience in customised glass solutions. Thus guaranteeing precision, innovative technical details and a discerning design - exclusively 'made in Germany'. It offers superb design freedom and its impressive transparency, made of 98% glass, means spaces are flooded with light.

Architects and homeowners alike want to maximum light to achieve the ‘wow’ factor with minimalist profiles and high transparency. The cero IV sliding door, with its discreet profile, provides creative design freedom and takes transparency to the next level by flooding rooms with natural light, without compromising on functionality or aesthetics.

cero IV has all the great features of cero II and cero III with the additional innovation of a structural glazing effect that makes the forend almost completely invisible offering even greater transparency levels than ever before - the top and bottom sight lines on the panel profile are only 15 mm wide each and the vertical only 2 mm! In addition, the cero IV also has a frame that can be set flush into the ceiling, just like all other cero systems. This allows the frame and profiles to disappear from view almost completely so the generous glass area can take centre stage.
