What Is a Shade Sail?

A shade sail is a patio or deck covering made from durable outdoor fabric that provides protection from the sun. Shade sails are installed by stretching the fabric and using tension to affix the corners of the shade to mounting points (like a pergola, post, tree or wall). Shade sails are considered a more affordable and versatile alternative to a hard-structure roof. Shade sails come in various shapes, sizes and colors to fit any style backyard.

Of course the main benefit of shade sails is sun protection. Most shade sails block between 90 to 95 percent of UV rays. There are some variations in UV absorption depending on the shade material’s weight color and the tightness of the weave, but the differences are typically less than five percent. But if you want maximum sun protection, know that heavier fabric, a tighter weave and darker colors generally block the most UV rays.

You also might want your shade sail to block rain. Shade sails are water resistant but not waterproof. A light sprinkle will roll off the shade, so it’s important to install it at an angle. In a heavy downpour, water will drip through the shade because it’s made from breathable woven fabric, which allows air to pass through and keep the shaded area cool. If you want full rain protection, look for a shade specifically categorized as waterproof.

Types of Shade Sails

If you can dream it, you can have it when it comes to shade sails. Typically, they’re available in three shapes: triangle, square and rectangle. But the combinations of style, installation technique and color are endless. Triangle shade sails offer the least amount of coverage but are easy to squeeze into awkward or small spaces. You can also layer multiple shades for more coverage, or simply to increase the wow factor.
