Which wall structure is meaningfully vapor-permeable?

Regarding the question: I believe the white bank had HaGeBau 2 years ago.

What is this? Integrated with heat recovery was unknown to me until now. The heat exchanger + technology takes up a lot of space. I only know of decentralized ventilation with ventilation openings outside in the reveal.

I believe we are talking about the same type of decentralized ventilation. I don't think I’m allowed to name manufacturers (?), but pretty much all major window manufacturers offer a decentralized ventilation installed in the window/in the reveal. How much throughput they have is another question, but at least the facade is not disfigured that way :)

How much throughput they have is another matter, but at least the facade is not disfigured

Go ahead and name the provider – it’s not forbidden. I’m still not quite clear on exactly what you mean. I googled and only found Endura Twist and Sigenia, which have a window rebate ventilation with heat recovery installed IN the window (or installed crosswise below the windowsill). Although that’s actually not really a window rebate ventilation. However, the nominal values are not convincing (only 62% heat recovery! at Sigenia and with 44dB noise). Otherwise, classic decentralized devices whose outdoor opening is located in the reveal. But not in the window. What exactly do you mean?

Or maybe rather for the "Kennichnicht" faction?

Kennermernit, bruchemernit, fottdomet.

It's not bad. Now you've learned something new again

Yes, I like to belong to the "learning more" faction - which doesn't mean that I then also acquire the objects of my learning. There I belong to the faction with the motto "simple rugged reliable".

The awakening comes at the latest with the direct comparison

That can be pretty much ruled out: that I would build a house twice for this purpose, or combine central and decentralized controlled residential ventilation systems in one house, just to be able to carry out this comparison.

Go ahead and name the provider – that's not forbidden. I'm still not quite clear on what exactly you mean. I googled and only found Endura Twist and Sigenia, which have integrated a window rebate ventilation with heat recovery in the window (or installed transversely below the windowsill). Although technically, that's not really window rebate ventilation. However, the nominal values are not convincing (only 62% heat recovery! at Sigenia and also with 44dB noise level). Otherwise, classic decentralized devices whose outside opening is located in the reveal. But not in the window. What exactly do you mean?

For example, the Geneo Inovent system from Rehau. Its values are also not impressive (71% heat recovery at 42dB), but inconspicuous and perhaps not a bad idea as part of a ventilation concept. However, I have never seen it in action, nor do I know anyone who has installed this or a similar system...

Thanks! I've never heard of it before.
