Sunbrella fabric is water resistant, and shade sails made from this fabric have to be installed with at least a 20 degree slope to allow water to run off and not pool on top of the sail. The chart at the right lists measurements for the amount of vertical drop recommended based on the size of the sail. Measurements are rounded.

Additionally, the perimeter of each sail is designed with a gentle curve inwards towards the center of the sail to control fabric tension. This inward curve will be approximately 6-8% of the length of each side of the shade sail. Therefore, when tension is placed on the shade sail, the fabric will not wrinkle or sag. Shade sails, when installed properly, do not sag or flap in the wind.

Due to manufacturing tolerances and fabric stretch, finished shade sail dimensions may vary 1.5" +/-.

Note: Due to the available Sunbrella fabric widths, and depending on the size ordered, your shade sail may have seams.

All standard size Sunbrella Square shade sails are made to order. Therefore, all sales are final. No returns or refunds will be accepted.
