Hello everyone,
I don’t know if this topic really belongs here – I’ll just start.

We are planning a new building and now face the question of whether we should use built-in or mounted blinds. We have already read so many different statements about this. Some say that the mounted ones contribute more to the insulation of the house than the built-in ones. Others say that this is nonsense and that mounted blinds are rather used for renovations.
Has anyone of you had any experience and can give us some advice?

Thanks
Veti99

Hello veti99,

Years ago, I had a lightweight expanded clay block prefabricated shell built and did the rest myself. I was quite impressed with the system, especially being able to have the roller shutter boxes integrated directly into the exterior walls. The company claims to have a special patent for this.

On the inside and outside, there is a solid thinner clay layer, so the plaster can easily be applied over the box surfaces. On the inside, there is a profile into which the clips of the roller shutter slats are hooked. For the belt outlet, there are various gypsum solutions. I chose the flush-mounted variant; the winder can be serviced if needed by removing the front panel.

I prefer built-in boxes because they largely ensure the homogeneity of the walls. The plastic attachments give me the creeps. The loosely inserted polystyrene board in such models seems quite careless compared to integrated box systems.

Take a look at Lechner Massivhaus GmbH.

Best regards

Be careful!
You are mixing up the terms there. Make sure you don’t end up buying exactly the opposite of what you actually want.

A mounted roller shutter box sits above the window frame, is usually as thick as the wall thickness, and can be plastered on the outside.

Depending on where the opening lid is (in case of repair or replacement work), the inside of the box can also be treated (wallpapered, plastered, etc.) depending on the manufacturer.

This roller shutter box is insulated and easy to install (often already pre-assembled at the factory when ordered together with the windows).
However, this is one of the more expensive options to buy roller shutters.

In contrast, the attached roller shutter box (or surface-mounted roller shutter) is located on the outside of the window frame and is usually visible.
Example photo:

Here, the service lid (maintenance lid) is on the outside.
In the drawing, the box is round. Square boxes are cheaper.
The advantage of this variant is that it is cheaper and can also be retrofitted relatively easily.

However, it is very rare in new buildings.

An intermediate solution (with a good price/performance ratio) is a mounted roller shutter box with plaster carrier plate.

Here, the lid can be plastered on the outside and thus disappears into the wall.
It either works with lintel offset (window is mounted further inside) or if the full thermal insulation is thick enough, the windows can also be mounted "normally" and then finished flush with the full thermal insulation.

It should be noted that the box becomes larger the higher the window units are (logically, the more roller shutter slats need to fit inside).

Especially for new buildings, I consider this variant interesting because the price plays a significant role.

Thanks Romeo for the print-ready picture article,

which I can refer to additionally. In my contribution, I understood all the variants you mentioned as the ones labeled "mounted" by veti, although this is not entirely correct due to the also possible prefix constructions.

What I understood by what veti calls "built-in" is something like the mentioned Lechner solid house solution, where the box is virtually a homogeneous part of the exterior wall. Since veti is building new, a real alternative where the size of the windows is not so severely restricted. With the mounted or prefix roller shutter, the effective window size always suffers, but not with the built-in variant. These "solid boxes" also serve as a support for the concrete ceiling through special reinforcements (a kind of "flat lintel," I'm not a structural engineer, sorry); structurally, they manage that. My new building is still standing.

All right, all-rounder!

I just wanted to give a brief overview of the possibilities because the question seemed a bit confusing to me.

But okay, let's wait and see how the thread starter comments further on this. Before we start a detailed discussion here, we first need to know how the builder imagines the whole thing and which open questions remain.

I am not familiar with the Lechner Massivhaus solution you mentioned.
Before I start searching and possibly say something silly, maybe you could post a link etc. so we know exactly what this is about.

Best regards,
Romeo

The requested link ...

is unfortunately not so easy to obtain. The company still exists, but in my opinion has a rather superficial site. It, in my opinion, greatly underestimates itself and has only put parts of the old brochures online.

Unfortunately, a detailed description of the boxes is missing. I only have paper photos from the construction myself; digital photography was not so widespread in 2001. If interested, one would have to have information material sent or approach the company at a trade fair, where they are usually represented.

I don't want to advertise here, but I don't know anyone else offering such a system. Time for the questioner to get in touch ...

Best regards
