We hung the curtains up the day they arrived when it was 90 degrees outside. It instantly dropped the temperature in the room and was surprised by how well the light color beige could block the light. The light weight sheen fabric con the top side is longer then the blackout fabric so it hangs lower to the floor. The quality is nice, weight is heavy and looks airy and soft yet reduces the heat like a pro. I am really glad I got these curtains.
