ᐅ Replacing Windows with Roller Shutter Boxes versus Without

I have an existing property with older windows and built-in roller shutters.

Now I would like to install new windows and have been considering removing the windows and roller shutter boxes to replace them with larger ones. This should provide better energy efficiency, or am I mistaken?

At some point, mounting external roller shutters is planned.

Thanks and best regards

I don’t know, please explain in more detail where this effect is supposed to come from.

Those would, first, protrude outward, and second, they would have to be planned as part of the window installation anyway (right?).

I used to manage a window factory, and I can’t follow your logic.

Weißnicht, erklär´ das mal näher, wo der Effekt herkommen soll.

Does he perhaps have old, uninsulated roller shutter boxes?
In that case, current double glazing would likely be an energy improvement.

I also don’t understand why someone would want externally mounted roller shutters later on. Now would be the right time to avoid this visual compromise.

First of all, thanks for the responses and the food for thought.
My idea was simply to remove the old roller shutter boxes and fill the resulting opening with a correspondingly sized window.
I assume that a newly installed window would be more airtight than an old window with a roller shutter box.
What I didn’t consider is that a subsequently mounted higher roller shutter would still have to be installed over the already taller window.

For me, the cost issue and the timing of expenses play the decisive role. Therefore, airtight comes before dark.
