ᐅ Retrofit Installation of a Roller Shutter in an External Thermal Insulation Composite System (ETICS)

Hello everyone,

unfortunately, we did not install a roller shutter on one window and would like to add one now. Thanks to permanent home office, the room is now being used differently than originally planned and therefore needs darkening for the summer.

The roller shutter box to be installed is 14x14cm (5.5x5.5 inches), and the external thermal insulation composite system (ETICS) is 17cm (6.7 inches) thick. My idea was to cut out exactly this 14x14cm (5.5x5.5 inches) section from the ETICS above the window and then install the roller shutter box in this space. This would leave about 3cm (1.2 inches) of ETICS remaining, and I wouldn’t have to do anything on the facade. Essentially, this is the same setup as with the other roller shutters.

Is this a reasonable approach? Or would this cause significant issues regarding insulation or thermal bridging? THANK YOU VERY MUCH IN ADVANCE 😀

Here is a schematic of my plan:

You write that your main concern is blackout. For that purpose alone, a good interior roller blind is enough. Do you also want heat protection? There are even clamp-on options for the outside available. It’s just about one window. Alternatively, a simple exterior venetian blind could also be considered.

If everything needs to look completely uniform, you will of course have to install a roller shutter, which means opening the wall again and then hoping that causes no issues. This is naturally more expensive. But no one can make that decision for you.

The roller shutter guides are attached to the window, and the box is mounted onto the guides. However, to be safe, I would also fix the box to the wall with construction adhesive.

But then you would need an installation space to get the box past the guides into the opening. I also find it hard to imagine that it can be installed properly at all.

How is the operation of the roller shutter planned? Do you have electricity there, or does a mechanical drive still need to be installed inside?

I can get power there with relatively little effort, so that’s not a problem 🙂 I also understand that it’s not an ideal solution, but that’s usually the case with retrofits. My main question is whether it can basically be done that way or not.

Well, it’s actually not that expensive. Around 200€ (about 220 USD) for a roller shutter plus motor seems quite reasonable to me for a permanent solution. I can install it myself. Clip-on versions like those from Blinos, for example, are significantly more expensive?!

What do you mean? The box is placed onto the rails beforehand and then simply pushed into the cavity from below. The rails are then firmly screwed in place.

€200 (about $220) for the roller shutter, including preparatory and finishing work??
