Blackout window shades (also called cellular blinds or cellular shades  ) have several aims to use: (1) they prevent light from penetrating into the room ( because of blackout window shades are perfect for bedrooms and media rooms), (2) they have large quantity of colors, and (3) they can be designed to be bottom-up/top-down.
  Get your cellular blinds motorized, cordless, with special lifting options, or with remote controls for easier and even safer operation. Available in several pleat sizes (the bigger pleat gives the better  insulation). Also choose between the single or double-celled window shades. Again, the more cells, the better your insulation.
  Blackout shades block 99% of all incoming light.  This is a popular option for bedrooms and home theaters.  You must know, that not all blinds and shades are equal when it comes to blackout, we've assembled the following selection of blackout blinds to make your selection even easier.
