Connection window/roller shutter

Hello, in the planning phase, you constantly come across new details. To prevent this: of course, we are doing the planning with the architect, but for the next planning meetings, I want to be as well-prepared as possible. So, here is the question: what I have learned is, - there are roller shutter boxes that are integrated into the shell construction - there are roller shutter boxes that form a unit with the window frame and are installed as one unit. Are there any other systems (which I might not know yet), and what are the main advantages and disadvantages of the two systems mentioned above? From my intuition, I would say that the latter (where the roller shutter box forms a unit with the window) can certainly be insulated and sealed more reliably against the masonry, or am I wrong? Thanks in advance Titus

The variant with the fully integrated roller shutter is the safest. The roller shutter is installed above the window and securely plastered.

Ave Socrates, Felix qui potuit rerum cognoscere causas. Nec scire fas est omnia Thank you for your reply. For proper understanding: You do mean the unit where the window maker delivers and installs the window and the roller shutter as one unit? Regards Titus
