Brick exterior wall with thermal insulation system

Hi, of course there is always the risk of mold forming, this is because houses built in this way are very airtight. But this can be counteracted by ventilating a lot. In the first year there is a lot of water in the walls that needs to dry and this can only be done by heating and ventilating.

Hello,
thank you for your answers.

One more question: What does "viel heizen und lüften" mean to you?

Is it enough to completely open the windows once a day for 10 to 20 minutes?

Hello Guest100, I can understand that you are skeptical about the insulation and if someone does not ventilate well, it can indeed cause a mold problem. In the first year in a new house, this can happen. You really have to heat and ventilate a lot to keep the wall dry.

A solidly built house generally requires much more than just regular ventilation. A thermal insulation composite system in this form is never diffusion-open!

Does anyone have experience with this type of insulation?
Acquaintances are concerned that these insulation panels make the walls too tight and moisture forms, which can lead to mold.

The company says that even the insulated wall can breathe and you have to ventilate in every house.

Are you building a KfW40/60 house?
In the former case, a ventilation system with heat recovery should actually be mandatory.. Then you don’t have to ventilate either.
