Sunshades Depot Waterproof Shade Sail Canopy Tent Replacement is the most cost effective shade solution per square foot. Shade Sails protect and shade your outdoor areas. Also known as Sun Sails, shade sails make beautiful additions to your patio, backyard, or other outdoor areas, while providing excellent protection from the sun and its harmful UV radiation. A shade sail is the perfect alternative to a traditional pergola or covered porch. Floating and curvaceous, Shade Sails make an attractive addition to any property, and with the right design, they can enhance the existing property with artistic or architectural flair and style. Sail Shades are wonderfully versatile; they can be attached to homes, fences, trees, or patio columns. In addition, they can be supported by wood posts or steel columns embedded in concrete footings. They can easily be taken down seasonally if necessary. Shade Sails are the ultimate in stylish sun protection. You can creatively design your own little shady area in a courtyard, pool, gardens, children's play areas, car spaces, and even entry ways. The perimeter of each sail is designed with a gentle catenary curve inwards toward the center of the sail to control the fabric tension. Shade sails have reinforced webbing around the perimeter, and steel D or "Delta" rings at each corner. When properly tensioned, shade sail fabric will not wrinkle, sag, or flap in the wind. The Polyester material will keep you cool and out of the hot sun. This unique state-of-the-art material will block the sun and UV rays, and will withstand damages caused by moisture and natural temperature extremes. Washable with regular soap and water. Heavy duty design will not droop or sag.
