Definitely black out. Super soft like silky on one side. Love that its wrinkle resisitant. Super easy to install. I would say my only dislike on this is I took down the slates for my slider and replaced with this, the curtain is not like weight to its pretty heavy so I added the middle curtain rod holder with out thinking about it. We'll as you can guess with the middle curtain rod holder the curtain can not be open all the way onle half way. Luckily its worked for me right now bc we are getting into winter so I dont use the slider as much in the summer. But I will eventually just need to get a thicker or more sturdy curtain rod. Still works tho. Great quality and thickness for the money for sure.

I absolutely love these curtains! The quality exceeded my expectations. The fabric is thick, blocks out light very well, and provides excellent privacy. The light beige color is beautiful and looks exactly like the pictures. They were easy to install and fit my sliding glass door perfectly. They also help keep the room cooler during the day. Great value for the price. I would definitely buy them again and highly recommend them!”

These are great

I am gonna be real I dont even have a curtain rod for this thing aside from blinds so it is hanging uo with a hair tie. I am absolutely going to need one for every window. I dont have a comparison other than every other curtain ive ever bought that said black out. So. Obviously light gets in around where the curtain isnt. Where the curtain is?? So good.

I really liked this curtain panel right out of the package. I did not notice much wrinkling at all. It was ready to hang directly out of the pack with min wrinkle removal. I actually have a great wrinkle releasing spray I use. They feel great And seem like true quality with a deep solid black color. They do in fact block out the sun well and truly are a great value for the money. I like that they are black all the way through on both sides. Most of my blackout curtains have different interior color than exterior. These are solid black and feel thick enough to last a long time. Very impressed by this curtain panel and plan on buying more. These are on sale as of the day I’m posting this, so don’t hesitate to grab them. You won’t regret it.

This curtain is not only blocks out the morning sun, it keeps the heat from our older windows from coming through. I'm amazed because these curtains are lighter for being 100' across. I'm very pleased.

Pretty color and good quality material. Not total blackout but definitely reduced light and looks really nice.

I bought the Joydeco Blackout Patio Sliding Door Curtains (84') as a creative solution to divide a room for my two teenagers. As a divorced dad, I needed a way to give each of them a little more privacy while they shared a space, and these worked out perfectly with a simple divider system. The curtains are thick, durable, and feel well made, especially for the price point. They hang nicely and definitely create the sense of two separate spaces, which has been a huge win for our household. As blackout curtains, they do a solid job, but I wouldn’t call them 100% blackout. They block most of the light, but during the day some sunlight still filters through—enough that I’d compare it to the glow of a small nightlight. For everyday use, that’s not a dealbreaker at all, but if you’re someone who works mid-shift and absolutely needs total darkness to sleep, you might want to consider something heavier duty. Overall, for what I needed—a practical, affordable, and well-made divider that also cuts down on light—these curtains were a great choice.

Exceeded my expectations for the cost. The fabric is soft and nice quality, hangs beautifully and the curtains glide easily without getting stuck, the black out ability is good. I bought black and looks great in teen boy room.

Worked for my room, had an old set of blackout curtains that started letting light in over the years due to washing. This changed the entire room back to pitch black. They are very soft and after handing for a day had no wrinkles great curtains
