Hello everyone,
We still need to make a decision about our interior walls at some point.
Our builder explained the (Q-)options for selecting the interior walls as follows:
• 12.5 mm gypsum fiberboard + 12.5 mm gypsum plasterboard
or
• 13.0 mm wood-based panel (e.g., OSB) + 12.5 mm gypsum plasterboard
Both options should be similar in load-bearing capacity, do you think so? I have a gut feeling that the option with the OSB panel might be somewhat stronger. On the other hand, I’m not really sure what additional load capacity we would need. I think a hanging kitchen cabinet sets the benchmark here, and both options should easily support that (even the new desired TV weighs only 35 kg).
Since we are planning a mechanical ventilation system with heat recovery, and it’s sometimes said that the air can be a bit drier with this system, one might argue that the double gypsum boarding could store and release twice as much moisture. But that is just a speculative theory of mine...
What would you do?
I appreciate your opinions because we will have to decide eventually 🙂.

I don’t want to focus the discussion too much on humidity now, but rather on what you think about the different wall constructions. Both options are fine; you can’t really go wrong. We chose double Fermacell in front of the installation layer.

hampshire26 Nov 2021 15:26There are two types of anchors for drywall. One screws directly into the drywall, while the other expands behind the drywall. The latter can hold a considerable amount of weight. You can quickly find drywall anchors by searching for them. "Spaxen" is faster and easier but can cause the hole in the drywall to fray.
Are these special screws that need to be used there, or can you also use Spax screws?
Could these possibly be the same types used for drywall? If so, I actually know both...
Is there any concern regarding the insulation if there is no separate installation wall and the thermal insulation starts directly there?

Have you seen the "sister thread"?
