Questions & Answers about Sunbrella Square Shade Sails

Q:

What is a shade sail, and how does it work?

A:

A shade sail is a modern, tensioned fabric canopy that provides effective sun protection for any outdoor space. Inspired by a ship's sail, it is made from durable, UV-resistant materials like high-density polyethylene (HDPE) or acrylic canvas. The sail is anchored, with about 150lbs of tension, at its corners to poles, walls, or other sturdy structures, creating a stable and wind-resistant cover. Known for their aesthetic appeal and versatility, shade sails are a popular solution for creating comfortable outdoor recreational environments in both residential and commercial settings, including patios, decks, pools, playgrounds, courtyards and dining areas.

Square Shade Sails made with Sunbrella Marine Fabric - 9 Stocked Colors for 2026 - BYC-SSSS


Here's one great sun protection solution - the Sunbrella Square Shade Sail. Courtyards, pool areas, gardens, children's play areas, car spaces, and even office building areas all benefit from the cool good looks of a Sunbrella Shade Sail. These sails can be mounted to a variety of surfaces and are easy to install. Now you can create a shaded area anywhere around your home or business.

Sunbrella's 100% solution dyed acrylic fabric is breathable, and provides excellent resistance fo fading in the sun to keep you cooler and more comfortable in hot weather. This state of the art material has a 10-Year UV warranty on Sunbrella Fabric - 2 years FULL!, remains nearly unaffected by moisture and natural temperature extremes. Sunbrella fabric is fade and water resistant. The near waterproof fabric also resists stains, mildew and rot. The perimeter of each sail is designed with a webbing for increased durability and a marine grade, stainless steel "Delta" or "D" ring at each corner. Shade sails, when installed properly, does not sag or flap in the wind.

These are made to order shade sails, therefore all sales are final. The dimensions supplied are for the finished sails dimension, corner to corner along a side. Your mounting points should account for the mounting/tensioning hardware (our turnbuckles+shackles are about 11") plus the fabric stretch of about 5% of the length of the side of sail. This is so you have enough space for your typical mounting hardware and the fabric stretch and still have enough space to tension the sun sail properly.


EXAMPLE: 15ft square sail (180 inches), would require that the mounting points be at least 200 inches apart at a minimum. 5% of 180" is 9", add that to 11" and you get 20" + the length of the side of 180" equals 200". Easy right?

Due to manufacturing tolerances and fabric stretch, sails dimensions may vary 1.5" plus or minus.

Note:Sunbrella shade fabric is water resistant, it MUST be mounted at an angle of at least 20 degrees to allow adequate water run off to prevent water pooling on top of the shade sail canopy. Please note that all Sunbrella shade sails are made to order and therefore these are NOT returnable.
