ᐅ Insulating a cold roof with compressed fiberglass insulation, cost

NordlysHello friends,
We have a bungalow with a slab measuring 13.5 by 10 meters (44 by 33 feet), and a hipped roof with a 30° pitch along the length and 45° on the short sides. So far, the roof is not insulated. The roof area is approximately 160 square meters (1,722 square feet), possibly a bit more. The ceiling between the floors is insulated. We use the attic not as living space but as a cellar substitute. It is accessible by a staircase, not a hatch, since the stairs are easier to use. A patio door separates the living area from the unheated attic well, providing good thermal separation. Unfortunately, this floor gets very cold in winter during frost — I’ve even had paint freeze — and very warm in summer. Now that we have some funds available, we have asked a carpenter to provide a quote for insulating the unheated attic floor (ceiling below the attic).
He is quoting us 8,500 gross for installing 200 mm (8 inches) of cavity insulation between the rafters, along with a vapor barrier and drywall lining, without plastering or painting.
Is this a fair price? Too expensive? Or even a good deal?

I thought this would be better than creating new threads on the same questions ...!? Personally, I consider two years as the limit for reopening a thread on the same topic instead of continuing the old one. However, I have often felt like calling someone a "grave robber" (or even did so) for trying to restart a conversation with a rare visitor after years, thinking it was pointless – and then, just a few hours or the next day, the person addressed would show up again. Maybe this also applies to @Dr Hix?

Alright, I’m learning and promise to improve!
On the other hand, I don’t even recall seeing comments like: “use the search function, this has already been discussed many times...” or similar. Personally, I think it’s better to add questions or answers to an existing “collection thread” and discuss the topic there, rather than reopening it as a new thread...!?

What I find most frustrating :-( are the threads that are started three times (first in the wrong category / with a poor title, then without including any basics in the initial post, and then a third time with no link to the original). And of course, the original posters who completely ignore the search function in the top right and come in with the 47th FAQ post.
Especially when the original poster’s immediate need for answers is met, but the thread has been inactive for less than two years, I always prefer to add to the existing discussion.

Hello everyone!
What criteria should be used to choose the thickness of the insulation board? Should it be decided more or less "by feel," following the idea that thicker is better, or is it better to look into the matter more thoroughly?
Our rafter depth is 24cm (9.4 inches). If I decide to insulate, should I also choose 24cm (9.4 inches) insulation, or is there fundamentally nothing against using 18cm (7 inches) insulation? The latter would be quite economical and immediately available for me, so that's why I'm asking. The 24cm (9.4 inches) option would cost me about 50-60% more.
Thanks in advance!

From the term "Klemmfilz," I infer that the insulation in the attic is visible, meaning there is no enclosed cavity between it and the living space climate of the loft. Therefore, I consider the thickness negligible, and 18 cm (7 inches) still a significant improvement compared to before.
