Although these drapes came out of the box needing a good ironing, once installed, they are indeed room-darkening and cut out much of the chill that seeps through the single-pane windows in my rental home.  I enjoy the coffee color that at first was a bit of a surprise, as it complements the neutral upholstery of my walls and furniture   I am quite pleased to have found a product of this quality at such a good price.
