These days it’s practically feasible to get your new windows, French doors and patio doors along with built in horizontal blinds. The blinds are fixed inside the double-glazing cavity.
Rotation of the slats, closing them completely or pulling up the blind for most light and vision can control the amount of sunlight entering via the window, when using Slatted Venetian blinds. Unfortunately, the flat surfaces of the slats accumulate dust and are not easy to clean. One reason that prompts people to favor this arrangement is that fabric curtains, festoon blinds, etc. have to be removed for washing or dry-cleaning.
Another problem is the positioning of the blinds on or above a standard glazed door. It’s all the more pronounced if you opt to have French, patio or bi-folding doors.
The solution is straightforward. Within the two panes of glass forming a double-glazed unit you get a dust-free unfilled space that can be utilized. The operation of the blinds is thru magnets that are attached to the window, enabling their normal operation. This could be achieved physically or electronically.

There are some drawbacks of this:
* The expense of replacing present units and the extra cost of integral blinds.
* The blinds can’t be repaired in case of a break down.
Unless you plan to replace windows or glazed doors, integral blinds are not a feasible option. But it’s a worthwhile option if you plan to buy, mostly when the glazing is in full sun or you need privacy.
Mostly integral blinds are guaranteed against crashing for many years. As the mechanism is operated thru remote, the chances of ill-treating or rough handling or are very remote.
Though the blinds are available in very many colors, for low-maintenance PVC or aluminum window frames many people opt for the safer options of white or neutral tones to have more of decorating choices.
