Frequently Asked Questions
Do permeable shade sails actually stop pooling?
Yes. Permeable HDPE mesh is woven so water and wind pass through the fabric instead of collecting on its surface. Proper slope and tensioning are still essential—permeability reduces pooling but won't fully prevent it if the sail is flat or loose.
How steep should the sail slope be for good drainage?
Aim for a noticeable slope: roughly 12-18 degrees is a practical target. In practice that means one corner should be at least several inches lower than the opposing corner depending on sail size. The goal is continuous runoff toward a low point rather than a flat surface.
Can I leave a permeable shade sail up in storms or winter?
For short storms the permeable fabric is better than solid canopies, but in severe weather, gale-force winds, or heavy ice loads you should remove the sail to avoid hardware damage. For winter, removing and storing the sail will extend its usable life—UV exposure and temperature cycles contribute to long-term wear.
