They offer many advantages: easy to install, practical to open and close with guides and a standard motorized system, protected, with the fabric, by a cassette box.
Anyone concerned about an annoying “flickering” effect need not worry: the fabric always remains perfectly tensioned thanks to gas springs incorporated in the guides.
If you think that your skylight or roof is too flat for our tension awnings, the Zerogradi model has been designed to function at any tilted angle.
