I'm going to do my livingroom ceiling (35m² ) with drywall and 7cm knauf ultracoustic p for insulation. Can you help me with the framework? I have to put them closer . I worry for the weight per screw. Thanks 👌 🇬🇷
If you are concerned about the heavy weight of the ceiling, then you can increase the number of profiles and, accordingly, their attachment points to the ceiling. I would also recommend using steel dowel-nails.
