Ladies...did a lot or research online. My home sits east and west and I don't have to tell you how hard it is to keep a house cool in the summer time. First I bought some window tinting thinking that is all that I would need to do. Well, it worked some but the evening sun still came blazing through my front windows and my AC still was still cycling all the time. Found these curtains and decided to just make the purchase as I could just send them back if they did not perform well. The windows in our home are very high with those half moon shaped ones at the top. That is a long long curtain to cover those. Purchased four set in the burgandy. Hung all for with just enough length to cover the half moon windows! On the front door, there are side lights and a half moon window. Just did some trimmiing, and with a little ingenuity of velcro the curtains are hanging perfectly. With the window film and the curtains I believe that the heat coming in and been dampened drastically as the AC is not running all the time and I set it to 78 degrees. I may have went above and beyond and they curtains should do the trick by themselves. They look great and are very soft and thick. When closed there is no light eminating through them. When I hang curtains I taken them all the way up to the ceiling if there is enough as It gives the illusion that the windows are taller than they really are and further out on the sides to really give good coverage and prevent no light leaks. Would definitely purchase these curtains again. Give them a try.
