ᐅ Renovating Beam Ceilings and Floors – Challenges and Questions

Hello everyone,
I’m new here, but I’ve owned my own home (an older building) for 6 years already. A little bit about me...
I’m Sven, 28 years old, and I’m looking for help because I’m a bit stuck.
I’m facing the problem that in my older house, the intermediate ceiling consists of wooden beams. From below, these are covered with drywall panels and a wooden understructure. Above the beams (which are 180mm (7 inches) deep), there is about 60mm (2.4 inches) of glass wool insulation, then cardboard, and finally a layer of wooden boards (see pictures).
When walking or moving normally on the upper floor, the noise is extremely loud below (like a hollow box or megaphone effect?).
Currently, the entire floor (13m x 6m (43ft x 20ft)) is not in use, but it is planned to become living space in the near future.
My idea is to remove the entire wooden board layer, fill the hollow space (no glass wool!), and then install a proper floor using Fermacell leveling panels. Above that, I plan to lay a vapor barrier, then an impact sound insulation layer made of compressed wood fibers, and finally OSB boards for a clean finish. On top of that, a solid wood floor could be installed.
Good idea? Any other opinions or suggestions?
Best regards,
Sven

Am I the original poster? Oh, no, but in general I dare to assume that the answer to this question can also be found in the mentioned source.
I assumed that the question referred to the intended construction (see the cited technical literature) – the actual construction was described by the original poster:

Good evening,
sorry for the late reply. I was just finishing installing a door frame in the kitchen...
The structure is as follows:
Gypsum board – battens – joist layer.
This setup is not designed to support heavy loads. That’s why my idea is to fill it with stone wool or wood fiber insulation. Although thermal insulation is not the main concern here.
Tomorrow, I will review the PDF from "ift Rosenheim."
Thanks in advance and have a nice Sunday evening!

Caspar202018 Mar 2018 20:20That’s why I’m asking about the current situation. The joists are only the 180mm (7 inches) ones. By now, it’s clear that there is practically nothing there.
So, what is it now? If the construction isn’t going to be thick on the joists, load-bearing inserts are needed, and on or between them a proper filling.

If the crawl space floor doesn’t support much weight, and you don’t want or can’t reinforce it structurally:
If you have enough ceiling height on the upper floor, you can lay OSB boards directly on the joists and then add weight on top using dry mineral loose fill or concrete block ballast. Above that, install an impact sound insulation layer and a screed with the complete floor build-up. However, you will need 15 – 18 cm (6 – 7 inches) above the joists, and the structure must be able to support this load.
