Hello everyone,

We have a heated basement.
During the inspection with the energy consultant, he said he wouldn’t do anything to the interior walls as long as it is not going to be used as a permanently occupied living space.

One room is now going to be an office/workroom. It won’t be used permanently, but maybe some improvements are still possible.

The room is heated with a standard radiator.
Can I simply use insulating plaster here to get some benefits, or would you rather recommend using insulation boards?

No dew point occurrence in exterior walls without interior insulation – how is that possible? Could you explain?

Even if this calculation supposedly shows no mold growth, the construction is very vulnerable, and if the conditions change, the situation can quickly become very different...
