Loft Living's room-darkening draperies from the Mervyn collection will insulate against temperature variations and block up to 90% of light, giving you daytime and nighttime privacy while they reduce glare in your room. The woven backing on these curtains, which are made from quality materials that are long-lasting, easy to clean, and resist wrinkling, also dampens sound and provides UV protection that can fade your floors and damage your furniture.
