Cero IV

"Solarlux’s cero sliding windows, which have won awards for their design, represent the pinnacle of aesthetic appeal, functionality and quality. The latest generation in the series, cero IV, offers greater-than-ever transparency in its incredibly slender building components. The model offers a structural glazing effect at the forend that renders the profile strip almost completely invisible – a feature you won’t find anywhere else on the market. This is possible thanks to the stepped-edge glazing used in the design. What’s more, the total percentage of glass in the sliding elements has been increased once more – the vertical sight lines of the cero IV’s profiles are each just 2 mm wide.

Despite the tweaks to the series design, the cero IV retains all the key features that proved so successful in its predecessors: Concealed glazing rebate ventilation reliably prevents a build-up of condensation in the double glazing. The weight of the building components – up to 1,000 kg – is channelled vertically into the running track profile of the floor track via the carriage built into the frame. As a further advantage, the thermal insulation could be optimized to a Uw value of up to 0.9 W/(m2K). Another noteworthy features is the new locking mechanism, which is now housed in the panel level to allow a smooth, uninterrupted flooring surface.
