Is a roller shutter possible for a large lift/slide door?

We have 3.01 m (rough wall opening), divided into two parts, so approx. 1.5 m louver length (aluminum).

Window construction had urgently advised back then not to make the louvers continuous, as they would be too unstable.

After plenty of storms in the first year, that was absolutely correct.

I estimate that with 2 m louver length, one should apply the planning brake....

It is also not bad to be able to control only the door blind individually. Then you can come in and out and the rest can remain shaded....

and that was exactly my intention with my 3.4m sliding door to divide the blinds. I can shade one side and still have access to the garden/terrace. Then of course controllable separately via a 4-gang switch.
