Before selecting your motorised system, consider the type of garage door you have: 1. Up-and-over garage door. Consists of a single panel that tilts upwards when opening. 2. Sliding garage door. Consists of multiple panels that open to the side. For this model, the motorised system is selected based on the size and weight of the door. For this type of door, Somfy recommends you use the GDK or Dexxo range. 3. Sectional garage door. Consists of multiple articulated panels that open towards the ceiling. 4. Roller garage door. Consisting of a curtain of roll-up slats, it coils into a box installed above the garage opening. For this type of door, we propose you use motorised systems especially designed for roller garage doors. 5. Swing garage door. Consists of two panels that open outwards. Swing-out garage doors most often use motorised systems with arms.
