Block Out Curtains
Block out curtains are made with a fabric that helps to block out sunlight, street lights and offers 100% privacy. The block out curtains also have excellent insulating properties and help to regulate room temperatures. For optimal temperature regulation with block out curtains, on hot summer days keep blinds drawn and open them up at night to allow the cool breeze in. Similarly, on cool winter days, open the curtains up during the day to allow the winter sun to warm the space and close them before it gets dark to trap the warmth inside.
