Hello,

During the shell construction, wall openings of 282cm (111 inches) in height were made for the floor-to-ceiling windows. Originally, 250cm (98 inches) high windows were agreed upon.
After deducting 10cm (4 inches) for the floor construction and 250cm (98 inches) for the window height, 22cm (9 inches) remained for the external venetian blind box.

Now it seems that roller shutter dimensions were planned here. There is no external venetian blind with this curtain height that has a box smaller than 30cm (12 inches).
That means the windows would have to be reduced to 241cm (95 inches), which I would really dislike.

Does anyone know of a system manufacturer that designs much smaller boxes? The plan was for the C80 slat with beading. Without beading, it might fit smaller, but after inspection, that is not an option. It is too unstable, and the supplier also advises against it.

One option mentioned to me would be to use façade boxes that disappear within the external thermal insulation composite system (ETICS / EIFS). However, that would likely affect the house’s thermal performance and require a new calculation by the energy consultant.

Does anyone here know of a solution for special external venetian blind boxes that have a particularly low installation height?

Who is carrying out the construction? General contractor or individual contracts?
If using individual contracts, who is managing the construction supervision?
Simply put, who designed the 282 (measurement unit)? And who specified the 250cm (98 inches) high windows with external blinds?
By the way, I would reconsider the 250cm (98 inches) height. I have 232cm (91 inches), which is already very pleasantly tall, and the components become quite heavy at that size.
With 232cm (91 inches), my window sashes were only allowed to be 1m (3.3 feet) wide; otherwise, the continuous window strips would not have held up over time.

The general contractor planned everything. I specified windows that are as close to ceiling height as possible, equipped with external venetian blinds. They then responded that, given the room height, windows with a height of 250 cm (98 inches) could be installed. We agreed to this in writing.

After things didn’t go as planned with the windows and the first window manufacturer he was working with withdrew, I got involved in the technical discussions.

But you don’t seem to be familiar with an especially slim frame system either, do you?

By the way, most of the floor-to-ceiling windows are quite narrow at about 1 m (3 ft 3 inches), with the rest being large lift-and-slide doors.

At a height of 250cm (98 inches), you need to install aluminum windows. Anything else will cause problems in the long run.

The boxes all have a height of 30cm (12 inches). The problem is that at a height of 250cm (98 inches), the "package" of the slats also requires a lot of space inside the box. If you happen to find boxes with a height of only 25cm (10 inches), your slats will not fit inside and will be visible when fully raised. I would personally find that annoying...

What clear ceiling height will you have?

Only 10cm (4 inches) for the floor buildup? That little? What does your floor buildup look like? What kind of insulation do you have? For us, the floor buildup is 15cm (6 inches) (1.5cm (0.6 inches) tile, 5cm (2 inches) screed, 2.5cm (1 inch) fixing panel, 6cm (2.4 inches) insulation), even though we have 12cm (5 inches) of XPS insulation under the slab...

Am I wrong to get the impression that your house is being planned very "on the run"?

I also find a 10cm (5 inch) floor structure quite thin. You should also discuss the transition from the floor to the window. Floor-to-ceiling windows don’t automatically mean there is no threshold, which many people often expect.
