Overlap is an innovative sectional door, thanks to its original opening system that doesn’t require ceiling tracks and reduces the internal protrusion by fifty percent. With Overlap the space inside the garage is best used and the door clearance is optimized, both in height and in width. A minimum of 200mm headroom is required. Overlap is equipped with the SilMotion operator embedded in the crossbar. This system operates the doors without visible ceiling tracks. The door raises, folds in half, turns below the ceiling, split in two sections and the lower one slides below the upper one.
