Forgetting perimeter insulation

The ceiling is, "fortunately," now 7 weeks behind schedule - so the construction company could still add another layer.

That means, so far only the basement walls are standing? - in that case, demolition wouldn't be half as tragic. However, I would rather involve a specialist lawyer than a construction expert, since I would immediately consider changing the contractor (who knows what else they might forget).

The tough counter-question is how many legal instances you can finance for a construction site. In that context, laying the insulation boards over the base slab might be the lesser evil (if indeed only thermal insulation and not also moisture insulation was omitted). In my opinion, a height adjustment before the basement ceiling goes on makes sense. The building permit would, in my opinion, have to be adapted to the new construction; I have no idea what KfW consequences that might have.

However, I can also well align with the viewpoint

Honestly, the insulation is not necessary

foot coldness is girls' stuff, and basements are for boys.

Isn't some things getting mixed up here? How can insulation on any ceiling help against forgotten insulation under the floor slab? Besides, he doesn't have a basement.

Where is the construction now? Can the ground floor walls still be raised?

You can also create the insulation "downwards" through an insulating layer between the slab and the screed. I would, however, completely disregard Tomtom's comment. The thermal insulation certificate is part of the building permit. I consider it very dangerous to dismiss it in such a way.

Oh alex85

But that does not mean that it is absolutely necessary. You have to look at the whole thing and decide if it is worth it to you.

Functionally, you do not have to insulate under the base plate in a modern building energy saving ordinance house.
Before it comes to a huge argument and you are the loser, take the money they offer you.

Furthermore: Hide. Too generalizing, the overall concept counts. If the base plate was planned with insulation, then there is a reason for it. Omitting it is possible, yes, but then has consequences for measures elsewhere.

Am I writing in Turkish or what? What do you mean by "look at the whole thing"? Just bring a solution if you know it so much better, but don't say it's not possible,

And have a nice evening, I'd rather watch a movie.
