I bought these for my husbands office TV room to block out all the light and glare on the TV . They keep the room nice and cool. Very nice curtains.  I would recommend washing them on gentle before hanging them. They seem good quality and will buy more for our bedroom. I hope that when winter hits Texas , these will help with keeping the cold out. We have a very old victorian home thats gets very cold during winter. I will write an update when winter hits.
