What are they?
Two sets of panels, one on top of the other that operate independently of each other.
Extremely versatile, giving excellent privacy and light control.
Not suitable for all windows as they can look to busy.
Reception and dining rooms.
Tier on Tier shutters have a quaint feel about them and do add the flexibility to open the top and bottom halves of the window independently. It does however leave a small gap between the upper and lower panels. If this is an issue we could look at a split tilt option instead.
