I ordered this sunshade to  help protect my garden from the intense sun. I have sun all day in my garden and delicate vegetables have always burned. So, when I saw the sun shade I knew it would work as perfect protection letting just enough sun in. It is currently placed low to the ground for small plants however I will raise it as they grow. I love this sunshade and it would work great on a rooftop terrace when the heat and sun are exteme.
