There is hardly any other sliding window like cero, which manages to combine large-area glass with the demands of modern architecture: individual elements can be up to six meters high and four meters wide, with a maximum area of 15 m² and a single weight of 1000 Kilo. The key are the elegant profiles, which are only 34 millimeters wide. The stable stainless steel guide technology is durable and robust. By touching a button or by hand, cero lifts the spatial boundaries and releases the entire house edge including corner posts. Certified to the RC3 resistance class, cero offers high break-in protection.
