Is there any convenient way to hang a dropped ceiling from a ridge beam? I have an existing extension with a ridge beam and open up. I want to install a "regular" interior ceiling and place the insulation on it. The span is 5.4m. It would be possible to dimension it as self-supporting, but that seems unnecessary.
The ridge beam is not quite at the ridge, it is offset so it is approximately 3.4m and 2m.

You can hang them up with either 45x45 or perforated tape in the beam. Then you need to frame up the ceiling and then attach the beam/perforated tape to the beam and then to the framework for the suspended ceiling. It's an advantage to use a line laser that you set up under the framework at about 100mm, then make sure you have 100mm in the middle of the beam before fastening the 45x45/perforated tape to the beam. That way it will be straight and neat. Is there any sparsely spaced ceiling as it is now? If so, you can also hang it up there.
The existing ceiling must go, so I can't hang from it. Do you think 45x45 is enough to hang from and nail 3(?) nails into the framework for the ceiling? I want to be able to walk/crawl on top of the ceiling without falling through... 
Is 45x120 enough if you keep it to a total length of 5.4m, and hang with a 45x45 about 2m from one side?

Okay, there are no trusses to take advantage of? Yes, if you put one in each stud to the subroof, they should hold. Otherwise, you can go up to 45x70. Yes, it might be an advantage not to reach the ground floor when you're insulating but are you only going to be up there when insulating, or will you use the space for something else? Unfortunately, I don't know anything about calculations or such, but I think it should work if it's for insulating and then holding up a layer of plasterboard. But maybe someone on the forum who knows more about sizing and spans can answer that?
