The fabric is a thick weave, but it's definitely not 90% sun blocking. It's maybe 70-80%. I created a retractable sunshade with it, and it does provide decent relief from the sun and heat. The measurements are a little off. 10x20 more like 9x19, and it was very crooked on one end. It's true that the grommets don't line up. It's a decent shade for the money, but don't expect perfection.
