Hello everyone,
we are currently renovating the entire house. The house is being given comprehensive insulation. The basement remains uninsulated on the outside; only the basement ceilings are insulated.
The basement is mostly unheated.
We have two floors as well as a basement, with the stairwell being heated. On each floor and in the basement, a door leads to the stairwell.
In the basement of the stairwell, we currently have some "thermal bridges".
Wall 1 runs towards the ground and is not insulated so far. Wall 2 leads to the storage room, which is cool. The floor also remains uninsulated.
The wall leading up to the stairs runs in the basement towards a cold laundry room. This wall cannot be insulated due to the stairs, not even from the other side.
We would like to insulate Wall 1 and Wall 2, ideally with minimal thickness (e.g. PU/PIR). Otherwise, we use mineral wool or wood fiber throughout the house.
What should we pay attention to in this regard? Our energy consultant said that this is too complicated, especially with regard to condensation, and suggested consulting a building physicist (because of only two walls?!).
Does insulating here make sense, and if so, how should we proceed?
Thank you very much!
