Planning to install a ceiling in the new garage, I have a question,
Should I use plasterboard or chipboard?
Plasterboard is best for fire safety, it's "dead," meaning it doesn't move as much when painted. But can you use plasterboard on cc120? If not, I need to install furring strips first at cc60.? Also, it's harder to screw into.
Chipboard moves, burns, but is better for screwing into and can be installed on cc120..? right?
This might not be a real question... but is it allowed to use chipboard or does it have to be plasterboard for fire safety reasons?
So what do you think? What am I missing?

CC 30 should be in the ceiling according to what I learned when I built my storage. Ended up with double gypsum in the end. If I'm going to hang something heavier than what an expander can handle, I aim for the framework.
The maximum CC distance might vary slightly from board to board. If you download the following manual from Gyproc http://www.gyproc.se/gyproc/bestall...tUNID=370652D4EBD94E22C125712900245799&m=memd you can read about cc400 for G's regular boards. But cc30 should also work well.
Then, I don't think particle board will manage with cc120, there seems to be a significant risk of bending and/or the boards crawling over the screw heads.
I would have put gypsum in the garage myself, but I have a welder too...

If you have the garage closer to the house than 2 meters and/or less than 2 meters to the property boundary, the garage must be fire-insulated, which requires double layers of gypsum for both walls and ceiling. However, the entire ceiling does not need to have double gypsum; I believe it's 2 meters in from each wall side that the ceiling should have double gypsum.
This was discussed in another thread a few weeks ago regarding fire classification in garages, and it was also mentioned that 24mm board material and insulation are sufficient for the fire classification. Thus, it doesn't need to be double drywall; it works with OSB + single drywall and insulation on top of that.
Correct me if I'm wrong?

My garage is EI 30 and constructed from the inside of the garage: 13mm gypsum-12mm plywood -95mm insulation rock wool -12mm plywood-13mm gypsum. Thus, double gypsum but a bit apart. I'd like to see someone put chipboard on 1200 c/c... wondering if you can get out of the garage before they come down. c/c 300 applies for the ceiling regardless of material. Maybe a panel can handle c/c 600
Sounds good. I'll have cc60 in the workshop area since the floor frame to the loft has cc60.
I'm trying to keep costs down and see that wall gypsum is half the price of ceiling gypsum per square meter. It will be a hell of a job to put up 1200x2500 sheets straight up with a ceiling height of 2.90 :S
