Insulate cold roof with clamp felt, price

I thought it would be better this way than opening new threads on the same questions ...!?

I personally consider two years as the limit to possibly start anew on the same question instead of attaching oneself. However, it has also often happened to me that I wanted to tell a "graverobber" (or even did tell them) how hopeless I found it, especially trying to resume a conversation with a rare visitor here after years – and after a few hours or the next day, the person addressed would check back in. Maybe that also applies to ?

I only noticed after I gave Dr. Hix an "i love it"

Alright, I am learning and vow to improve! On the other hand, I don't think I've even read comments like: "use the search function, this has been discussed dozens of times ...." or similar. Personally, I think it's not wrong to add questions or answers in an existing "collective thread" and discuss the topic rather than starting it anew ....!?

I feel the same way. My “favorites” :-( are, by the way, the threads that start three times (first in the wrong section / dumb title, then without any basics in the opening post, then a third time and all without linking to the original). And of course the TEs who, completely ignoring that there’s a "search" at the top right, come in as the forty-seventh with an FAQ. Especially when the thread starter’s urgent need for answers is satisfied but the thread idles for less than two years, I always prefer to attach myself.

Hello everyone!

According to which criteria should one choose the thickness of the insulation felt? Basically "winging it" under the motto the thicker the better, or should this topic be examined more closely?

Our rafter depth is 24 cm. Should I therefore also choose 24 cm in case of a decision in favor of insulation, or is there fundamentally no objection to 18 cm insulation? The latter would be quite inexpensive and immediately available for me, hence the question. The 24 cm would cost me about 50-60% more.

Thanks in advance!

From "Klemmfilz" I deduce here that the insulation of the attic is visible, meaning there is no enclosed cavity between it and the room climate of the loft. Therefore, I consider the thickness negligible and 18 cm still a significant improvement compared to before.

Thank you , that matches my previous layman’s understanding. Your confirmation helps me further....

The attic does not have to be super insulated, but it should represent an improvement compared to an unventilated cold roof.
