Blink enclosed blinds with LowE glass give you a maintenance-free option for controlling levels of doorglass light and privacy plus additional energy savings over regular glass. A single control lets you raise, lower, or stop anywhere in between, and tilt for full privacy, no privacy, or anything in between. Blink blinds provide full coverage of your doorglass, so sunlight, moonlight, and streetlights stay outunless you invite them in. Blinds are enclosed between two panels of glass, you never need to dust simply clean the glass like a window. The enclosed design protects the blinds to retain their new look, and eliminates the banging and swinging experienced with traditional blinds. The single operator without cords lets you raise, lower or tilt the blinds in an easy smooth movement. These replacement windows have been designed for use with steel and fiberglass doors.
