Zenna Home Josephine Thermal Energy Wrap Window Panels, Set of 2, Grey

I got these curtains to be used under their regular curtains for my son's bedroom as the colors are crimson and black. They are unlike any I have seen before as there are slits toward the end of each rod pocket panel for the ends to turn to enclose the window. Additionally, there are velcro dots so that you can "lock" the two panels together so that less heat will escape into the room. They are also room-darkening, but not a total dark as they do allow light to filter through. The fabric has a very pretty slubbed look to it, sort of like a slubbed silk. They are supposed to be insulating, but they are not somewhat stiff like some insulated curtains. Right now I don't really know whether they insulate a lot or just a little. I like them so much I am going to buy some for my own bedroom to be used as liners under the curtain in place of the sheers I have now.

The thermal shield Josephine curtains say 99% light blocking but I would say 75% they are lightweight and insulated three sided blackout good curtains and all noise reducing may be some help but if your looking for total blackout curtains I would buy eclipse blackout curtains that's what I have in my living room and they are very good I got the thermal curtains for my bedroom curtains are very nice looking blocks out 75% of the light so that works for me happy with them plus not too heavy on my curtain rod my room looks much better now good price good curtains comes with energy-saving fasteners included just stick to your wall I got the two panel curtains set so a very good deal save on my heating and cooling bills I got black colored curtains but with sunlight coming in a little more gray than black but I like anyways
