Myth?! "Breathing Walls" What is the truth?

You know what that means now?

Yep, I've already received one for another quote.

The funny thing is that I posted the text a second time (quoted the text from and noted that I reposted the post without links and that the old post can be deleted since I can't do it myself). However, this post was deleted. Strange admin...

I can live well with a reprimand

There are people who live happily on Rügen.

I am glad to have my CO2 measuring device in the solid wood block house.

It reminds me daily that it is time to ventilate.

However, the bathroom mirror has never fogged up, no matter how long and hot the shower is.

I keep reading these and similar sentences on the internet

Yes, you have to be careful with this internet. Sometimes there's nonsense there. :p

Of course, walls cannot breathe. However, it is largely undisputed that the different properties of walls have an impact on the well-being in residential buildings. If one takes the term breathing as a metaphor, one can - if one wishes - quite understand the core of the statement in a figurative sense.
