Trusted quality and value from Alion Home brand products. The Sunshade Panel is knitted with industry leading quality breathable HDPE (High Density Polyethylene) material. Lock stitch knitting stops screen from tearing or fraying. Achieves high industry privacy rating while allowing light, cool breezes, and water to pass through. While the main purpose is to keep unwanted eyes from peering onto your patio, backyard, pool or balcony, our panels also serve as wind break, shade for patio plants, a barrier to keep your dogs from barking at everything, and often a classy upgrade to an old fence/railing. They let air pass through to keep your outdoor area cool and water is never an issue. They are maintenance free, just put it up and enjoy years of privacy and shade.
