Sectional doors open vertically upwards, thereby creating space in front of and behind the opening. The door sections are parked directly underneath the ceiling, vertically above the structural opening, vertically up-and over or following the pitch of the roof. The exceptional breadth and depth of the range, thermal performance and certified safety make a sectional door convincing in every respect.
