I ordered this to use over my deck for our pool. The deck is not finished yet so I am not able to put it up yet. But the material looks like it would keep the sun out very well. Perfect because it’s very light weight. Exactly what we need for our deck area. Careful when you opening packaging. Packaged very tightly so if you￼ use scissors careful not to cut sail.  I will update once it is installed.￼
