Our Shade sails are designed for shade and are not waterproof.
Shade sails must be correctly installed. Your shade sail should be installed firm and tight so as to reduce windflap in the shade fabric. Shade fabric that is loose and sloppy will cause premature failure due to mechanical breakdown. An incorrectly designed and/or installed shade sail will trap water (and other debris) creating excessive load on both the shade sail and it’s fixing points.
