Ground-level terrace exit with façade insulation

I don't find that unimportant at all, at least I don't know of any perimeter insulation that is not compressive resistant.
A flat rate only works with the poor thermal bridge surcharge of 0.10 W/(m² K).
This often already ruins a KfW55, which should be worthwhile just because of the higher subsidy. And moisture protection is not proven this way either.
I only use such measures in monument protection if nothing else is really possible, or if garages are located inside the house or stairs lead to unheated basements. It becomes very difficult to improve a thermal bridge afterwards. But often the blower door test also becomes a problem there.

Thank you for your comments, but that is not the topic here. It sounds strange, but due to the new higher subsidies, we get more for KfW70 than for KfW55, which would also cost us more.

That will not really work out, as all expensive trades are also in KfW70. Neither the building services nor the windows and doors will change. Possibly it is 2 cm more insulation on the wall or roof, or a thermal bridge surcharge of 0.05 W/(m² K) or less will suffice. Only then must the calculated proof be provided.

But all good, I wish you success

In our case, it actually works out thanks to the increase in funding at the beginning of the year. (Last year we applied for KfW55, then withdrew it and applied for KfW70)

We had checker plates installed. It’s not exactly visually appealing, but it was simply the quickest and easiest solution for now. We’re still not happy with the type of fastening, as it seems too loose to us. Our building contractor still needs to take care of that.

Just the other day, I realized that we will have the same problem with the front door, since it is also raised by about one step. We’ll see if we can simply leave out the insulation under the door.

I’m still surprised that there are so few solutions on the internet about this topic. This issue actually affects everyone who insulates the facade and replaces doors at the same time, doesn’t it?

Not everyone makes a problem out of it,...
