Choosing the right vertical blinds
Window treatments should facilitate looking out of the window from within the room and prevent or hamper looking inside the room. This can be achieved by the proper shades, coverings and shutters. While ventilation is unaffected the view from the window is enhanced while privacy is maintained. Choosing the right vertical blinds for the purpose will go a long way in decorating the inside of the house while maintaining privacy as well. The kind of blinds chosen for privacy will depend on the kind of house and where the window is facing.
If you live in a flat with a window facing the other flat you will need to have blinds that will completely block out any view from the outside.
