cero III sliding doors
Triple glazed option achieves Uw values of around 0.8 W/m²K, suitable for passive homes
The stunning bespoke thermally insulated aluminium profile system cero sliding door benefits from 40 years of Solarlux experience in customised glass solutions, guaranteeing precision, innovative technical details and a discerning design - exclusively 'made in Germany'. It offers superb design freedom with its impressive transparency via the expansive glass panels, which open up rooms to make the line between the inside and out dissolve away.
The cero III with its ultra-slim 34 mm profile sight line provides a huge 98% daylight transparency. Individual sliding elements can reach up to 6 metres high with a total area of 15 m², so spaces are flooded with light, providing a feeling of airiness and grandeur.
The cero III triple glazed option achieves Uw values of around 0.8 W/m²K, suitable for passive homes depending on the size, glazing and configuration choices. As well as winning many design awards, cero III is PAS 24:2016 certificated and Secured by Design (SBD) accredited, the UK official police security initiative.
