A: Cellular shades, a popular option for those looking for light and energy efficiency, come in regular top down/bottom up designs as well as two-in-one options. The conventional top down/bottom up feature gives you the option of raising your shade from the window sill or opening it from the top (top down).
There's also a two-in-one option that works very similarly to the traditional top down/bottom up method. The two-in-one cellular shades give you the benefit of both an opaque room darkening cellular shade as well as a sheer, light filtering one. These shades literally have two shades on top of one another to give you the benefits of both worlds. Where the opaque cellular shade stops, the sheer one begins.
These are convenient and easy to use since they work the same as regular top down/bottom up shades. You can fill your window with an opaque shade and, when you want more light, simply pull down the top rail to expose the sheer shade. This is a great alternative for those who like both privacy and soft light.
