As I stated on my last review of the same type of curtains but in Sage, these do not match the description that is shown on Wayfair.com website or the plastic wrap the curtains are in. In other words, nowhere is it mentioned that they are thermal. However the color, Mineral is true and the curtains hang very nice. They are soft but remember: they are not lined so if you live in an HOA community, ( I, don't) and need the curtain to be lined in a white backing, these are not. On both the Sage and Mineral curtains some light "filters" through but still provide privacy. I hung mine in my Den and Living room. I will not be returning and still will do business with Wayfair. Thanks to all the Customer Service Representatives! You all are the BEST!
