The “cero” sliding window affords a view from inside to outside with almost no frame at all. This is because with a visible width of just 34 millimeters, slender profiles enable a 98-percent glass surface. Even with individual elements measuring up to 15 square meters, the sliding window can easily be opened and shut manually. For increased comfort, Solarlux also offers a motor drive. Boasting resistance class RC3 certification, “cero” additionally offers a high level of burglary protection. Thanks to the flush floor rail, the sliding window is barrier-free.
