Hello everyone,
I need your advice regarding impact sound insulation. We are in the final stages of planning. Our prefab house provider has planned a floor heating system panel 30-3 as impact sound insulation under the screed on the upper floor.
Alternatively, they offer a 30-5 mineral-based impact sound insulation board.
This would improve the soundproofing of the ceiling.
The additional cost is around 500 euros.
Is it really worth switching to the mineral insulation for impact sound, or is it better to neglect it since the improvement is minimal and invest the money elsewhere?
The children’s rooms are on the upper floor, so we are considering this carefully.
Thank you very much

clad with 12.5mm (0.5 inch) gypsum fiberboard. How is the gypsum fiberboard attached to the joist structure? If you double-layer the ceiling underneath and decouple it well from the joists (using a spring channel or hanging system), you can improve impact sound insulation a bit, depending on the floor construction above and the adjacent building elements.

In our house, we have a comparison: part of the upper floor is insulated with expanded polystyrene (EPS) (hallway, bedroom, bathroom), while the two children’s rooms are insulated with Rockwool. The flooring is the same laminate everywhere except for the bathroom. The difference is clear when the kids drive their toy cars—whether they are in their rooms or in the hallway/bedroom. Generally, stone wool provides better sound insulation than EPS, probably due to its greater mass.
