Roof insulation with under-rafter insulation

Hallooooooooo:(:D

Hello,

Preliminary exterior wall: 17.5 Ytong with 16 CM Neopor as an external thermal insulation composite system ETICS or whatever it's called :D.

ETICS --> External Thermal Insulation Composite System

plus a 3 cm styrofoam cavity insulation.

Why styrofoam?

Is that OK like this?

Whether that is OK cannot be said due to (reasons known to you)
See this

Then the forum no longer makes sense to me. It doesn't matter anyway, I'm done with the planning and I saved the energy consultant; the neighbor took care of that.

Hello,

Then the forum makes no sense to me anymore.

It does make sense. Because if you accept the given tips, you can be sure that your house is really "planned", components and heating technology are optimally coordinated and not just randomly put together.

Doesn't matter, I'm done with the planning and I saved the energy consultant, the neighbor took that over.

Is your neighbor an energy consultant or something like that?

I have no idea what you do for a living but when I read your posts it gives the impression that you want to make money here and land jobs. I gave you all the data from the description etc. also on other topics but you don’t want to say anything. The paid energy consultant could do that ;) My house is finalized in terms of planning but I know that I didn’t find any help on the internet. More likely in the green forum but there the biggest architects are also running around :D

So what now? :confused:

You just don't want to understand, do you?
With your information, no reliable, valid statements can be made about whether it is sufficient for your house or not. The statement "I want KfW70, have triple glazing, aerated concrete, 16cm ETICS and 200mm insulation mat" simply isn't enough. Even your "neighbor" can't do anything with these few data points, bet on it??? ;)

It wouldn't help you if someone said Wow, 200mm insulation in the roof, that's already something. Just do it like that.

Why is it so hard to understand that house planning is not about just putting together four walls and installing a heating system? The house is a complicated structure that must be planned down to the detail considering many parameters.
