Designer Glass Doors blinds are not commonly used for doors as there are certain difficulties related to it. Firstly, when these blinds roll up horizontally, they can stack at the top of the door and come in the pathway. Sometimes the doors are made high enough in order to avoid this. Secondly the cords of the horizontal blinds are longer in length and can stack in the doorway. Both these features can be bothersome.
On the brighter side, if you come across blinds made of advanced technology, you can overcome these simple difficulties. When used for bringing in light or sunlight to the room, the horizontal blinds for sliding glass doors are more convenient then the vertical ones.
