If you are looking for curtains to keep heat out! Do yourself a favor and purchase these !! (The blackout is an added bonus) I live in a second floor apartment and during summer it’s about 90 degrees up here. I was looking for ways to keep it cooler without needing to run an AC all day and I can’t believe the difference these have made. I searched for curtains for days until I gave in and bought these and I am not disappointed! The thermal white lined curtains are great ! Heavy and not too bad to look at. I would say they have kept my apartment no more than 70-75 degrees and that’s huge ! Considering how hot it can be up here.
