Looking for total darkness during the day? Blackout drapes and curtains are the best window treatment option for when you need to completely block out the natural sun or busy city lights. The high performance materials protect against harmful UV rays, keep your room better insulated, lower your energy bill year round, reduce glare on TVs, and prevent fading from the sun on furnishings. Custom blackout curtains are the ideal choice for day sleepers, nurseries, and entertainment rooms.
