We just screened in our patio because of mosquitoes. Love it and have been enjoying it a lot however in this summer heat the ceiling fan does give us some relief but we really needed some curtains to block the sun and be water proof. With the rain and sprinkler system these do a great job keeping our furniture from getting soaked. Patio still gets wet but these were just what we were looking for. Grommets are large and slide easily.
