I'm renovating the bathroom and part of it involves lowering the ceiling and installing recessed spotlights. The bathroom is relatively small, 230x140. The plan is to glue and plug primary studs (https://www.bauhaus.se/norgips-primarregel-45) around the room in the walls (one concrete wall and three lightweight concrete walls) and then secondary studs (https://www.bauhaus.se/norgips-sekundarregel-45-85) across at cc45. Now to the question; do you attach the secondary stud from underneath with self-drilling screws? Do the screw heads become a problem when it's time to drywall? Or do you screw the secondary stud at the top in the small "flange" that sticks out?
Feel free to suggest alternatives otherwise! Thanks in advance!

So you should screw the secondary profiles into the old ceiling if I have understood it correctly. Then you can do as you wrote except that you should not have primary profiles as a frame but a regular track. The primary is used as a "beam" if the secondaries hang freely.
Well, I was thinking of lowering the ceiling a few cm to allow for electrical conduits to be installed there, so I was planning to attach a frame to the walls and place the secondary beams in the frame, meaning they will only be attached to the frame. I'm attaching a picture of how I was thinking... but I think I can't screw them from below as the gypsum will ride on the screw heads that fasten the secondary beams together.

Put a 70 track around. 25 mm secondaries instead of 45 mm and a primary in the middle anchored to the ceiling at one or two points. The screw head you're concerned about can be a 13 mm sheet metal screw with a thin head.Z Zingow said:
