De DucoSun Linear (200-300) is available with fixed or with electronically adjustable louvre blades. These are installed on site in the support structure (horizontal or vertical). The fixed louvre blades are installed below an angle of 45°. Together with the louvre blade, in the form of a parallelogram, this provides a particularly attractive effect. If the electronically adjustable louvre blades are closed, they have an optimum solar shading effect. The closed louvre blades and the façade area are aligned, forming one harmonious unit.
