Timber panel construction - exterior wall thickness = 10 cm sufficient?

In my opinion, you can save at most 50% of energy costs through insulation. That is about 80 euros per month. In my opinion, the insulation is not worth it over the next 20 years.

Then I hope that there are only a few heirs. The only greater scourge of humanity than "brokers" are "brokers and communities of heirs". Tomorrow is Friday. If you have access to the building file then, we can still chime in over the weekend. If you can research the history of the sales efforts, that would be very helpful. How much "competitor pressure" do you have?

I can only ask the broker tomorrow. He said there are 28 competitors. The house is now for sale for the first time.

You can save at most 50% on energy costs through insulation in my opinion. That is about 80 euros per month. In my opinion, insulation does not pay off over the next 20 years.

I have now calculated your assumption and after 20 years it would be just under 20,000 euros.

It's not just about saving money - if the stealing cold of the walls makes life miserable, then one cannot even warm oneself with the thought that the costs of insulation wouldn't be recovered.

Mhh, so in your opinion I shouldn’t insulate, because otherwise there’s a risk of mold?

No, that means you should not only have the topic of insulation on your list but also the topic of ventilation. Possibly a decentralized ventilation system will then be necessary in addition to insulation. Otherwise, 180 kWh/sqm for an unrenovated 1980s building is relatively normal.

Is such a house worth it at all if you only have about €60,000 for renovation? (Still inexperienced

I am critical. With that budget, firstly there shouldn’t be many unexpected costs, and secondly you’ll have to do a lot yourselves. How old are the kitchen and bathroom? What about the electrical system? What heating is installed and is it still in good condition?

Am I critical. First, not much can be done with the budget, and second, you have to do quite a bit yourselves. How old are the kitchen and bathroom? What about the electrical system? What kind of heating is installed, and is it still in good condition?

- Kitchen would need renovation (wallpaper & floor)
- Bathroom is already renovated
- Electrical system would need complete renewal (from 1980)
- Heating system was renewed, but old pipes

No, that means you not only have to have the issue of insulation on the list but also the issue of ventilation. Possibly a decentralized ventilation system will be necessary for the insulation.

Otherwise, 180 kWh/sqm for an unrenovated 1980 building is relatively normal for us.

I suppose something like that would exceed our budget. :(
