All weather commercial shade sails can be installed over small businesses or large public areas like shopping centers, sports stadiums, hotels, and restaurants to provide shade. Shade sails are popular in Los Angeles for building car shades at malls, markets, and businesses as an eco-friendly alternative to concrete structures. Retractable and louvre shade sails are also popular at sports centers and hotels with pools to keep the water clean and cool while allowing private yet open-air swimming.
