All of our black-out blind kits provide complete blackout when applied correctly to the window. They can be hung either way on your window and can be cut to size by the customer with no hemming required (no-fray material). Everything required to hang the easy night blinds is included in the kits for both home and travel. TRAVEL (suction cups & removable frame fasteners for home or travel) HOME (removable frame fasteners only) Provides 100% block out if hung correctly. The Easynight Blinds have a silver backing to reflect the heat (not suitable for all Body Corp rules). The soft Velcro pads are attached to the silver side of the blind to correspond with the removable fasteners placed on the window frames. They are a light material making them suitable for travel and to hang via the suction cups or removable frame fasteners for all sizes.
