French Doors With Internal Blinds
These fiberglass doors are made by the Therma-Tru Corporation. They come with louvers that are installed between the two pieces of tempered glass. The controls allow you to tilt the blinds up or down or to raise them to the top of the glass leaving all but about 4" of clear view area below the raised blinds. I have installed quite a few of these and people are happy with them. They like not having surface mount blinds flopping around on the door and the neater appearance that they provide.
These blinds are available in either the full lite french doors pictured below or in a few different styles of doors with 1/2 glass and panels below.
