Install cable duct on external facade or inside

Such cable ducts would definitely not be an option for me.

Hm the roller shutter on the outside has guide rails on the sides anyway. If the cable duct is the same color as the guide rail and you stick it right next to it, you can hardly see it from the outside anymore. I would always do it on the outside in case the chipping option does not work for some reason.

Alternative 4: Make a virtue out of necessity - inside and take cables from Gi Gambarelli with the corresponding porcelain holders for surface mounting. If it fits the style, it looks beautiful.

Why do there even have to be roller shutters there? Personally, I think nothing of roller shutters at all. What is supposed to be achieved with them? Darkening? Heat protection? Burglary protection?

Darkening and of course heat protection, obviously. I don’t want to know how hot it would have gotten here last summer without [Rollläden].

Have you (if it suits the character of the house) ever thought about shutters?
