30 years of developing and manufacturing experience led to the invention of our minimum frame, maximum glass sliding door system cero. cero opens rooms with extensive glass panels – impressive transparency dissolves the line between inside and outside.

Three versions are available: cero I; uninsulated, cero II; thermally broken with thermally toughened safety glass (ESG) and cero III; triple glazed, achieving thermal transmittance values of UW=0.76 W/m2K meeting passive house standards.

Despite its minimal frame width of only 34 mm panel sizes of 4 metres width and 6 metres height remain possible with a glazed surface area of up to 15 m2 and 1000 kg panel weight.

The possibilities of combining the system elements of cero as sliding, fixed and corner elements are mutually limitless. They provide amazing degrees of freedom in design and layout. Single, twin and triple track depths of 97, 197 and 303 mm allow for wheelchair access according to DIN 18040. Panel-integrated stainless steel runners ensure an even spread of weight and easy sliding with little wear.

cero creates a seamless transition between the inside and outside as smoothly as possible. The glass’ maximum transparency enables 98% of the incident light to pass through directly. Still, the product can offer impressive resistance to the elements: the system is tested for wind loads up to class B4 (EN12 210 / EN 1627), protection against driving rain up to class 9A (EN 12 208 / EN 1027) and air permeability up to class 4 (EN 12 207 / EN 12 211). As all Solarlux products, cero is certified by a renowned, external testing institute and continuously improved and tested in-house to always meet the highest quality standards. The same applies for safety. cero III is certified to RC3 standards (DIN EN 1627), achieving the highest burglar resistance class. Special features are available upon request, such as electronic locking mechanisms, additional magnetic lock monitoring (reed contact), integrated break glass detectors and the integration of the entire system in existing master security systems.

cero is available powder coated in RAL and DB colours and as anodised aluminium to EURAS. Special colours are available on request enabling an endless wealth of design options.

The system’s sophisticated design and technology was awarded with the iF Gold Award in the category “Building Technology”, and the German Design Award in the category “Building and Elements”.

If you decide on cero you also decide on the highest service level provided by authorised Solarlux partners. You will be allocated to one contact person who will be taking over the entire project management from planning to execution putting your mind at ease.

For over 30 years Solarlux has been the definite market leading manufacturer of bi-folding doors and glass extensions. Solarlux is not only a company with strong family traditions but we also live by our core values.

Based in Lower Saxony, Germany, all products are bespoke designed and manufactured in one building. Solarlux has always been dedicated to the manufacture of precisely engineered systems that meet both the highest quality and security expectations and standards. Therefore, we work together with renowned external testing institutes. Our in-house Research and Development Department is continuously looking at ways on improving and refining our systems which have led to the creation of our new r.evolutionary bi-folding door. The new system combines the unique elements of Solarlux’s most popular systems SL60, SL70 and SL80 and of course, also combines the unique technical features from each, such as the slimmest sight lines of only 99mm and the lowest U-value of 0.80.

September 2016 saw the official opening of the new Solarlux Campus and factory. The innovative state-of-the-art building represents the company’s core values: innovation, design and superior quality. The premises exceeds passive house standards and produces more energy than is used.

Solarlux has established a network of authorised partners throughout the UK. We have always been keen to work very closely together with our dealers and ensuring their expertise through certified training courses.  Find your regional Solarlux partner on our dealer map or visit our Welwyn Garden City Showroom.

Taking on challenges, realising visions and exceeding expectations. Whether it be a new construction or a renovation, a private building project or a complex façade design – it is our ambition to develop an individual solution for every property.

Engineering the exceptional this is what we stand for.

Together with our authorised partners we will be exhibiting at several shows this year. Showcasing Solarlux’s innovative bi-folding doors, the minimalistic sliding window <em>cero</em> and our thermally insulated glass extension we are looking forward to welcoming you on our stand for product demonstration and individual project advice.
