Top down, bottom up shades are just that – they allow you to lower the top portion of your shades, and roll up the lower portion of your shades. They are useful when you are looking for an unobstructed view of your window, but still want to maintain some sort of privacy. Typically, these sort of shades still operate with a traditional pull cord, continuous cord loop, or with enhanced motorized controls.
