High-Quality Material: This shade sail is made of 100% brand new high-density polyester that can block up to 95% of the sun's UV rays. It is a waterproof fabric, but it is recommended to maintain a tilt angle during installation. Temperature Reduction: Lower the temperature by up to 15 degrees under the shade, reducing your property's cooling cost and energy consumption. Curve Edge Design: The shade sails have curves in the edges to set up tension through the sail. As the corners of the sail are tensioned, the edge curves try to straighten, pulling the fabric tight. This design not only improves the pull strength but also effectively prevents the shade sail from drooping. Easy Installation and Maintenance: Detailed instructions are provided to ensure easy installation. It is easy to clean with soap and water, and it is fade-resistant, won't stain, or tear. This sun shade sail solution is widely used over a patio, lawn, garden, pool, pond, or deck. Custom Size and Warranty: We offer custom-sized sun shade sails to meet all your requirements. Our sun shade sails come with a 3-year limited warranty under normal weather and usage conditions.
