Editing Window blind (section)

===Roller===
Roller blinds are a type of window blind that is typically made from a [[polyester]] fabric wrapped around a plastic or metal roller. The roller may either be exposed or enclosed inside of a frame and can be placed at the top of the window recess or outside of the recess. To control the roller blind there is typically a chain or string on either side of the blind. When the side chain is pulled one direction the roller will raise, and if pulled in the opposite direction it will lower instead.

Some manufacturers also produce a version of roller blinds with two layers of fabric, sometimes referred to as double roller blinds, for even greater control of light filtration through a window. Typically, one layer will be made of a [[sheer fabric]] that can be used to reduce glare, with a second layer that typically includes a blackout lining for even greater filtration when necessary.
