our old building has now been completely gutted inside: plaster removed, floors taken out and excavated, etc.
The house will receive internal insulation using wood fiber insulation boards or optionally Multipor. Who is the best contact for calculating which material thicknesses can be used for the insulation (keywords: dew point, vapor diffusion, etc.)?
Thanks for your advice

Contact your energy consultant.I assume you are referring to a construction project in Germany. However, based on the thread history of the original poster, it concerns a property in Hungary, so it is not subject to the Energy Saving Ordinance or KfW programs, which are usually the areas of expertise of energy consultants.https://www.instagram.com/11antgmxde/

Does anyone have a contact who can calculate this for me—of course for a fee?
Feel free to send me a private message.

The house is planned to receive internal insulation made of wood fiber insulation boards or optionally Multipor. Who would be the best contact to calculate which material thicknesses can be used for the insulation (keywords: dew point, vapor diffusion, etc.)? I can’t recommend anyone specifically, but I can still give you a useful tip.
Try using xxx.ubakus.de/u-wert-rechner/
This tool is also used by many energy consultants, etc. The demo version is sufficient for you. In 99% of cases, a professional would confirm the results (based on my own experience). Of course, a professional can suggest alternatives that such a “basic” calculator cannot. But at least you’ll have an idea of the direction your insulation thickness should take.

danabanana7 Sep 2021 08:38Very interesting! I have uploaded the results as screenshots:
As far as I understand, I can work with wood fiber boards at a thickness of 80mm (3.1 inches).
I tested with 100mm (3.9 inches) insulation, but this results in a drying time of over 100 days during summer.
At the house location, winter temperatures rarely drop below -5°C (23°F), while in summer temperatures can exceed 30 to sometimes 40°C (86 to 104°F) for many weeks.
I hope I am interpreting the results correctly.
What do you think about the outcome? Can the insulation work this way?
