Window Shades are generally one piece of material that raise and lower with ease.
Roman Shades are used to block out the sun completely. They are unique in that they are made up of slats which stack up perfectly on top of each other when the shade is opened. One of the reasons that roman shades are so popular is that when opened, they present a smooth appearance, unlike most types of vertical shades. These stylish shades are usually opened by pulling on a cord, which allows you to adjust the degree to which they are open or closed. Roman shades can be constructed out of many different materials from aluminum to plastic to wood and even fabric. This endless array of designs means that roman shades can be used for almost any application and fit in seamlessly with your existing decor.
Cellular Shades are also an extremely popular choice. These are very much like the traditional pleated shades, except they feature two or more layers of material that are joined in "pleats" that trap air. This aids in providing insulation, which is great for people who value energy efficiency. These have a reputation of being the most energy efficient and sound proof shades available. As a result, their popularity has grown dramatically with the increased global interest in green technology. The degree of insulation depends on the size of the cells in the blinds that you purchase and the number of cells incorporated into the design. Any number of cells from one to three are available for an even more customized fit to suit your needs.
Roller Shades are highly convenient due to the rolling mechanism that is used to operate them. The top of the shade is fitted just above or near the top of the window. Cloth or high quality vinyl is attached to the top and bottom bars of the shade. The shade is opened and closed by turning a bar or operating a cord mechanism to lower and raise the shade. This is a very neat, attractive setup that allows a wide choice of designs and finishes. There are two types of roller shade. There is the standard option, in which the shade rolls out of the back of the mechanism, and the Reverse Roller Shade, in which the shade rolls out of the front of the mechanism, providing a more streamlined appearance. The Reverse Roller Shade is the most popular type of roller shade.
Pleated Shades feature a pleated accordion design that is decorative as well as functional. They look and act like shades, while the pleats offer the crisp linear definition of blinds.
