This product was described as "black-out" and "thermal" so we ordered it for our baby boy's nursery. In actuality, these curtains are extremely lightweight, no more than a thin bed sheet. They block no light and there is no way they would provide any insulation. The style and colors match the picture, but that's about it. We ordered a different pair of thermal black-out curtains for our daughter's nursery and these actually block light and cool air from the windows, this is what we would expect from thermal black-out curtains.
