ᐅ Venetian blind or slatted roller blind for sun protection?

The living/dining area of our single-family house currently in planning faces entirely south and features a roughly 3.7-meter (12 feet) high glass front with triple glazing.

My initial idea was to install roller shutters in front of the windows for security against break-ins and as sun protection. However, I was told that
a) conventional roller shutters are no longer feasible due to the window height
b) roller shutters do not provide protection against break-ins
c) the roller shutter boxes built into the wall represent a weak point in thermal insulation

Point c) is clear to me, but what about a) and b)? Is that correct? What alternatives do I have, for example, an externally mounted electric louvered blind?

A small cathedral as well? One of our clients wanted that too (attachment) 😉

Whether a roller shutter box is a thermal weak spot is debatable; energy saving regulations do not allow much room here. What is certain is that you will not be able to install conventional roller shutters. In the attachment, you will also find a picture of a flush-mounted external roller shutter; if you have enough space above the window element, this is an alternative. These external roller shutters are also available with visible guide rails on both sides; much depends on your building’s architecture. Both systems can be motorized.

By the way, you will probably not even be allowed to install standard plastic windows; the structural engineer will likely object. The "cathedral" unit is an aluminum-reinforced window element.

Again, you should ask your architect what alternatives they can offer.
