Installation
Modern purpose-made shade sails vary in shape, size and color and there is trend towards installing multiple sails, sometimes overlapping, thereby adding some form and style to its function. Shade sails are tensioned usually by means of either a stainless steel turnbuckle or a pulley system fixed at each corner of the sail. For permanently fixed sails, the turnbuckle provides the best means of fixing the canopy since it generally allows more tension to be applied. For sails that are used on an occasional bases, the pulley system is more practical since it can be set up and taken down in a couple of minutes.
For domestic applications of shade sails it is recommended to install them with a quick release "snap hook" at each corner. This allows the sail shade to be quickly taken down in high wind conditions or during the winter season. Correct installation requires that adequate and quite considerable tension be applied to the sail to allow it to adopt its correct shape and prevent flapping in the wind. It is important to ensure that the mounting points are substantial and secure both to be able to accept the required initial tension and to absorb the loads created by wind gusts hitting the sail.
