We have planned windows for cross ventilation, but would rather follow Epis' opinion. It is definitely not airtight up there.

Is it really a true cold roof, i.e. a double-shell roof?

Do you then always go up and down there to open and close windows?!

Hello,

we do have two windows (each in the gable) in the attic, but they are only opened for cleaning.

The air exchange in the attic is done by "Lüfterziegel".

This works quite well.

The temperatures in our attic do fluctuate between summer and winter - you cannot really call it "constant" there.

Regards,

Dirk

At our place (Pultdach), perforated metal sheets were integrated into the roof overhang at the front and back, allowing air to circulate throughout the entire roof. Unfortunately, I did not take a picture of it.

That only works well with a double-shell roof - if you have, for example, a roof window in it, it's usually no good with that.
