Solarlux cero: the sliding window that vanishes
More than a sliding window. cero opens rooms with extensive glass panels so that the line between inside and outside dissolves. It is made in Germany, with over 30 years of Solarlux experience behind it.
Features that matter
cero uses stainless steel carriages and rails for easy, low-wear sliding, with an integrated roller unit for even load distribution. Electric operation can be installed on request. Intelligent drainage is hidden within the profile.
The sliding elements reach up to 15 m² of glass, with a 34 mm all-round frame, and you can combine sliding, fixed and corner elements. It has passed a longevity test of 100,000 opening and closing operations. RC2 and RC3 burglary-protection versions are optional.
- Slim sightlines and about 98% glass
- Motorised operation with group control
- Corner and multi-track solutions
