A. Manufacture of the sail is done using a steel cable placed around its perimeter. Tensioning the cable creates a curve on each side, resulting in a decrease in the shaded area that can reach between 25% and 35% of the projected surface in large sails.
B. Each sail has a corner fixation system to prevent tearing during tensioning. These fixations also reduce a small percentage of the shaded area.
Usually, all anchoring points of the sail have a tensioning system, and occasionally one of them is fixed and lacks it.
This fixed point should be mounted directly on a facade. Additionally, this point will be the most perpendicular to the sun, as the separation between the sail and the facade will be smaller, resulting in a larger shaded area.
