The ES45 system comes with a graceful and minimal design, which can be used for sliding windows as well as doors within the permissible dimensions. The system comes with various track options to maximize the number of designs possible in this system right from the simple 2 track 2-panel design to the monorail system where opening a small area via sliding is made possible. The number of components used in this system guarantees a long-term performance in terms of airtightness, water tightness, and noise reduction.
