Types of Windows and Guidelines for which Window Treatment to Use
Clerestory Window
Definition: A shallow window set near the ceiling. It is sometimes placed in the slope of a beamed ceiling.
Possible Treatments: If they don’t cause a privacy problem and the glare from light is not an issue, they should be left as they are. If the light does need control – Venetian blinds with very long control cords or pleated blinds.
Palladian Window (Venetian, Arched Top)
Definition: A window composed of an arched head and below divided into three compartments by two mullions usually consisting of one large center light and two narrow sidelights.
Possible Treatments: Often the top part of the window is left untreated and any method of curtains used below as shown in the photograph below. However there are many types of blinds that are designed especially for this type of window and they fan out over the window. The only problem with most of them is that they are often fixed and you then lose the detail of the window frame.

Glass Wall
Definition: Generally a grouping of windows fixed together to cover a large expanse, often to maximize views.
Possible Treatments: It is often difficult to select, as there is seldom any room above or to the sides to place tracks or stack backs of curtains. The widths of the windows are usually too wide for most types of blinds, as they tend to sag. A group of smaller blinds can work but then you get gaps and they can often catch when moving them up and down. A lightweight cellular type of blind could work, as that would also minimize the loss of view. Vertical louvers are a good solution as you can turn them to alter the light, and slide them back quite neatly to the inside of the window. This does encroach on the view but it is minimal.
This glass wall (grouping of windows) has been dressed with vertical louvers. As you can see they can be turned to let light in, or closed to keep the light out.
Skylight
Definition: A fixed or opening window in the roof. Some are pivoting; some are fixed and have ventilating units attached. Some have winding mechanisms and others have the new electronic controls, with the option of rain sensors for self-closing windows! They are used for letting natural light into internal spaces and for ventilation purposes.
Possible Treatments: They are frequently badly decorated as they are designed to let light in and not for covering, but if blocking out that natural light is necessary, Venetian, duette or pleatex blinds fixed to the window at both ends can be used. Sheers or nets on expanding wire are a simple and cost effective option.
