Am about to change windows, what bothers about the surface mounted shutter box windows is that the shutter boxes take away a lot of light, space.
Completely do without shutters with 3 fach. Glazing and e.g. inside only Raffstore, blinds, does that work?
Front shutters is what it's called...but you can also do without shutters altogether...it's your house after all....
Take a complete system. Window with factory-installed roller shutter recommended. Not bad, but such a roller shutter box takes about 15cm+ takes away the window area.
