Our Sunbrella Shade Sails feature Marine Grade Sunbrella Awning breathable fabric to keep you cooler and more comfortable in hot weather. This state of the art material provides a UV protection factor of up to 98% and is unaffected by moisture and natural temperature extremes. Sunbrella fabric is a solution dyed acrylic that is fade and water resistant. The near waterproof fabric also resists stains, mildew, and rot. The perimeter of each sail contains seatbelt type webbing for increased strength and durability. Each corner has a welded, solid, marine grade, stainless steel attachment ring to aid in attaching to a structurally sound fixing point. Sunbrella warrants its fabric with a limited 10 year warranty. Thread, webbing, and D-Rings have a 2 year warranty.

All custom shade sails are designed with a reduction of approximately 10% of your attachment point measurements in many cases. This is done to allow enough space for the mounting hardware, fabric stretch, and to tension the sail. All final shade sail measurements will be approximate due to tolerances during the fabricating process. Due to the limited available Sunbrella fabric widths, there will be seams approximately every 40-57 inches.

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 have a maximum depth, or gore, of approximately 6-10% of the length of that side of the shade sail. Therefore, when tension is placed on the shade sail, the fabric will not wrinkle. Shade sails, when installed properly, do not sag or flap in the wind.

Note: Sunbrella material is water resistant, it must be mounted at an angle of at least 20 degrees to allow water run off.

Determining the amount of Slope/Angle for your Sunbrella Shade Sail

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. Below is a simple equation and example to determine the amount of vertical drop from one attachment point of the sail to the opposite attachment point of the sail to allow water run off. A 20 degree slope can be estimated - if one corner is attached and you walk to another corner, then the sail must change height 3.6ft every 10ft you walk.

If you have a shade sail that is a 15 foot square the amount of angle/slope will be 5 feet 5 inches. You can determine this slope amount by using the equation: Sail Length x .36 = Amount of Slope

15 Feet x .36 = 5.25 Feet which is about 5 Feet 3 Inches.

Therefore it is best to attach two points of your sail 5 Feet 3 Inches lower than the two higher points to allow water run off.

Triangle Custom Shade Sail Skinny Corner of two long sides
Skinny Corner on Custom Triangle Shade Sail

CAUTION: If the area you wish to shade is much longer on one side and not very wide on the other, the inward curve will protrude far enough into the sails shape, the corner of the two long sides will become a skinny strap. This may be unexpected to the average person. So please be careful when designing your shade sails.

To the right is how a custom triangle shade sail corner may appear as the the two dimensions approaches twice the length of a third dimension. The inward curve of the two long sides makes the fabric converge quickly.
