Block out blinds is a type of window treatment that is designed to completely block out light from entering a room. It is typically made from a thick, opaque material that is designed to prevent any light from penetrating the fabric.

Block out blinds are ideal for use in bedrooms, nurseries, or any other room where complete darkness is desired. They are available in a range of materials, including polyester, PVC, and fabric, and can be operated manually or motorized.

One of the main benefits of block out blinds is their ability to provide total privacy and light control. They can block out not only sunlight but also streetlights and car headlights, ensuring complete darkness and privacy within a room.
