For a house provider, special emphasis is placed on the diffusion-open wall construction in the house description. This is also one of the main reasons why the provider does not install a central ventilation system. Another reason is that biomass (smaller dust particles, etc. in the air) is attracted in the pipe system, and contamination (mold formation) can occur quite quickly in the distribution system.
Now I have two problems with this.
1. We tended to want a ventilation system, and the provider generally does not install one.
2. We now do not know how great this diffusion-open wall construction is and whether it might be sensible to do without the ventilation system because of it.
Here is briefly the wall construction (Swedish house facade) from inside to outside:
15 mm high-quality Fermacell solid construction panels
40 mm wooden frame construction with Knauf Insulation 40 mm WLG 040
0.2 mm vapor retarder SD 100 m
160 mm wooden frame construction with Knauf Insulation 160 mm WLG 040
30 mm wood fiber insulation board
24 mm battens
Approx. 20 mm SL cladding, spruce (color according to color chart)
It would be very nice if someone could explain to me the advantage of this diffusion-open wall construction compared to other walls with wooden stud construction. Especially the relation to the ventilation system would also be important to us. With Hagemann Haus, we would have to do without this ventilation system after all.
