I have a newly built house from 2012 (ok, not brand new anymore, but not old either 😉 ).
I would like to improve the sound insulation of the exposed ceiling joists from the ground floor by adding something from below afterward.
I was thinking, as I sat on the sofa staring at it, to insulate between the ceiling joists (10 x 24 cm) with about 10 cm (4 inches) of dense/heavy stone wool insulation, attach support battens on both sides, and line the spaces between the joists with gypsum fiberboards, then fill and paint them white (so the ceiling joists remain visible, with white fiberboards between them).
Attached is a photo of the current ceiling.
Do you have any comments on this assembly or suggestions for an alternative? The main goal is to reduce the noise from children playing upstairs to the floor below, as it is quite extreme. Of course, most of it is caused by vibrations in the structure, which are difficult to control, but we want to minimize it as much as possible. I know it is best to address the noise at the source, but since there is already about 20 cm (8 inches) of floor build-up upstairs and we can’t easily add a few centimeters (inches) of height there, for example with gypsum fiberboard composite or insulation panels, we are looking for something to reduce the noise from below. Upstairs, we have already replaced the laminate flooring with carpet in the playroom, for example.
Best regards
