I have bought a newly built house with approximately 5 linear meters of interior walls constructed in the simplest manner with single gypsum + 70mm stud + single gypsum. My idea is to reinforce these walls with a sheet (OSB/plywood) and then gypsum. The walls are only plastered and painted so not particularly arduous, but only part of the wall is an interior wall, and the rest is an exterior wall. For this reason, I don't want to extend the wall out towards the living room as I would then have to continue over a large section that already has a stable construction. Additionally, the ceiling height in the living room is 4 meters. The alternative I am considering is to instead dismantle the wall from the back, cut OSB/plywood to fit between the studs and attach it with angle brackets to the studs. I would then fill with insulation (if this helps to make the wall rigid?) and finally attach OSB/plywood + gypsum in the usual way since on this side of the wall, it's not a problem to build with 12mm.
What I am wondering about is the solution with the sheet mounted from behind/inside against the gypsum - what do you think about this solution? The purpose is mainly stability, quality feel (avoiding the "hollow" sound when knocking on the wall), and acoustics. Of course, I also want to be able to hang pictures etc. without having to find studs.
It's the red walls that are being reinforced!
