Stunning and suitable for passive house standards
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 with its impressive transparency via the expansive glass panels which opens 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 width with a total area of 15 m², this means spaces are flooded with light providing a feeling of airiness and grandeur. The cero III triple glazed option achieves Uw values of around 0.8W/m2k, suitable for passive homes depending on the size, glazing and configuration choices.

The cero III sliding door is PAS 24:2016 certified
Window and door regulations for new builds:
With the desire for slimmer and slimmer aluminium door profiles, security may be compromised. Any windows and doors for new builds, as part of DOC Q Building regulations, must have a security standard that has been shown to be tested to meet the PAS 24 security standards.
What does PAS 24 stand for? PAS 24 is a British minimum standard which means there are no higher or lower grades, so it either passes or fails: PAS 24:2016 Enhanced security performance requirements for doorsets and windows in the UK. The product is tested by an independent 'United Kingdom Accreditation Service (UKAS)' body to ensure compliance and fit for purpose.
As well as winning many design awards, cero III is PAS 24:2016 certificated and Secured by Design (SBD) which is the UK official police security initiative that works to improve the security of buildings and their immediate surroundings to provide safe places to live, work, shop and visit. Don't settle for anything less than a quality product.
