ᐅ What is the best way to cover a ceiling?

Hello everyone,

I just signed up here, my name is Valentin. I am currently building an L-shaped bungalow.

Now to my question:
In about 4 weeks, I need to cover the ceiling (wooden beams). After the ceiling is insulated and the vapor barrier is installed, drywall or Fermacell boards will be applied. I want to ask you which one should be used: drywall or Fermacell, and what thickness would be recommended.
I recently heard that Fermacell is more expensive but significantly easier to work with, and that you need less additional materials (battens, screws). Can this be confirmed?

I would appreciate your help...

Fermacell is generally somewhat more expensive, but the gypsum fiberboards are also more durable and less sensitive to moisture compared to standard gypsum plasterboards (drywall). In addition, they have better fire resistance. A more robust and thicker substructure is recommended since the boards are significantly heavier. The thickness of the underlying battens should at least match the penetration depth of the screws; otherwise, the vapor barrier could be perforated, compromising its effectiveness. So, you won’t save on fastening materials. However, only narrow joints need to be filled with joint compound.

There is no paper surface like on gypsum plasterboard, which could be damaged when removing wallpaper later on. Small items can also be attached directly with a screw, as the load-bearing capacity is better.
