Note: Accurate measurement is crucial to getting the right size for your classroom window. Before ordering, please measure the window. Add 3 inches to your window width and 3 inches to your length before choosing your size to ensure a good fit. Includes: Made of 100% premium, blackout polyester fabric and sold as a single piece. These room-darkening blackout curtains are available in additional colors, suitable for classrooms, French doors, patios, living rooms, kitchens, and home offices. Easy to use: Unlike many window blinds and blackout curtains, no tools, hardware, mounting clips, or drilling are required. Strong adhesive strips keep the curtain in place. You only need to release the Velcro fastener at the top so that the curtain falls over the window. Then press the bottom edge of the curtain to completely block the view of intruders. Darkening and Privacy: These soft and durable door window covers are made from innovative triple-weave technology, which can ensure complete darkening. It is important that they completely darken the classroom to ensure the safety of everyone effectively. Our shades are safe alternatives to blackout curtains or blackout blinds for windows.
