Roller Blinds, also known as roll-up blinds, are named for their mechanism of rolling the entire fabric up and down via a roller tube, in contrast to traditional fabric curtains that open and close horizontally. They are widely used in formal settings such as offices, office buildings, banks, and schools, making them one of the most common types of office blinds.

Based on the operation method, they can be classified into: bead-chain roller blinds, spring-operated roller blinds, and motorized roller blinds.

According to the Chinese building industry standard JG/T 254-2009 "Soft Roller Blinds for Buildings" issued by the Ministry of Housing and Urban-Rural Development of the People's Republic of China on June 18, 2009, they are defined as: sunshade devices that use a rolling mechanism to extend and retract flexible fabric at an angle greater than 75 degrees from the horizontal plane.

Sunlight Fabric: This fabric is typically made of polyester blended with PVC and woven using a special method. It features small pinhole-like openings, which allow some sunlight to pass through, hence the name "sunlight fabric" or "view-through fabric." Suitable for general office spaces, sunlight fabric roller blinds allow a view of the outside scenery while effectively blocking UV rays. They are widely used in office environments. Due to the unique properties of the material, they are generally fire-retardant.

Semi-Blackout Fabric: This fabric blocks visibility, preventing people from seeing indoor or outdoor scenes, but still allows light to pass through. It is the most common type of semi-blackout fabric, effectively blocking UV rays while offering slightly less transparency than sunlight fabric.

Full-Blackout Fabric: This category includes white-coated full-blackout, silver-coated full-blackout, and non-coated full-blackout fabrics, among others. They are suitable for areas with strong sunlight exposure or environments requiring complete darkness, such as bedrooms, media conference rooms, and west-facing windows exposed to intense afternoon sun. Due to the material’s excellent light-blocking and heat insulation properties, it is also one of the most common choices for office blinds.
