Roller Shades Window Requirements
Different windows require different specifications for window treatments. Measuring and assessing a window for roller shades applies and you'll need to consider the shape, size, location, and depth of your window before you settle on a specific type of roller shade.
Roller shades come as horizontal bars so it's a given that they are only made for vertical windows. Roller shades do not come in styles that fit odd shaped windows or sliding glass doors. With this in mind, consider the width and height of your window. If you've determined that either room darkening or light filtering roller shades are your best option, remember that the maximum width of a roller shade is 98”.
If you want a roller shade with a spring lift system, your window can only be 72” wide. Height restrictions also depend on the type of control system you want. Chain loop control systems come in roller blinds up to 120” in height and spring lift or Softrise systems are available in lengths up to 96”.
Also consider the location of your window. If the window is mostly shaded during the day, you may want to consider a light filtering or room darkening shade that can either diffuse or block light during the day but provide adequate privacy at night. If your room gets lots of sun but faces a neighbor or a street, you may want to consider a light filtering roller shade that allows some control over the type of light entering your home but still provides some privacy. Windows that have a view, however, usually require a special window treatment, like sheerweave roller shades, that allow you to enjoy your view while still diffusing bright light. Keep in mind though that these solar shades and sheerweave shades do not provide the same degree of privacy as the light filtering or room darkening roller shades.
The depth of each window is important, too. Although roller shades come with different size brackets so you can choose the distance between the roller shade and your window, roller shades also come in two roll styles. Standard rolls roll up the shade from the back of the roller bar where as reverse rolls roll the shade from the front.
With Standard rolls, the shade is pulled down from behind the roll, leaving little room between the shade and the window. This is a great option for windows that are shallow and have little decorative trim, like those in Orangeries. Reverse rolls, however, keep in the shade fabric in front of the roll, leaving considerable distance between the roll and the window. This is the best choice for deep windows with lots of trim.
Also keep in mind that manufacturers trim their rolls to different lengths and will compensate for the width of your window depending on their usually adjustments. Check with either your retailer or the manufacturer to find out more.
