Promising review:"Purchased these for my studio, which is in an old mill. I wanted them for their insulating properties more than to block out the light because my studio loses a lot of heat at night due to its enormous windows. The curtains/drapes work great for both — I am especially pleased with how well they help keep the space from losing heat! Before having the curtains the space would lose about 8 degrees in temperature overnight (which in the winter is a significant amount, especially in the northeast). Now, with the curtains, the space no longer loses heat overnight! It is now so nice to go into my studio in the morning and find it still toasty warm!" —Noname
