These window panels are perfect for me. Have been looking for a while now for a flexible option for my back windows. My windows are aluminum at the top which prevent me from putting blinds or shade. With this type of panel I can use a tension rod or attach them with the hooks that are provided with these panels . These are a great deal.

Purchasing another set for the kitchen windows. All of mine face West and they work great. They go behind my regular curtains.

Outstanding block out 100 of light keeps the cold out vary thick nicely made will be buying more

These curtains do block light, but mine did not come with the pin hooks required to attach them too the existing curtains. Additionally they are thinner than most curtains. See photos.

Nice. Blocks light as promised. ***I would highly recommend using a double rod instead of hooking liner to curtain.
