cero sliding door
34 mm all-round frame, 98% glass, 100% secure - simply stunning!

Ultra-Slim profiled cero opens up rooms with extensive glass panels

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.

With ultra-slim 34 mm profile sight lines, the individual sliding elements can reach up to 6 metres in height and make up a total area of 15 m² (cero III). All in all, the system is made of 98% glass providing a huge 98% daylight transparency. Spaces are flooded with light providing a feeling of airiness and grandeur

cero II Key features

  • A mere 34mm narrow profile width gives a symmetrical, minimalist design and maximum transparency.
  • High-quality aluminium available in your choice of colour (RAL, DB powder coating and Eloxal), 30 RAL colours as standard.
  • Extra large toughened glass panels up to 12 m2 provides maximum transparency through 98% glass.
  • Intelligent drainage, tested and certified for wind load and air/driving rain permeability.
  • Versatile ground plans inc. flush-fitted for accessible living, multi-track and various corner situations can be executed
  • Easy glide stainless steel carriages/rails for long-term safe running properties
  • Motorisation options inc. electro-mechanical locking/unlocking and integrated insect protection

In addition

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. Extremely large toughened glass panels up to 15 m2.

Cero IV Also triple glazed, it 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.

The cero II & cero III sliding doors are PAS 24:2016 certificated

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, the cero II & cero III sliding doors are PAS 24:2016 certificated and Secured by Design (SBD) accredited 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.
