Hello,
We are currently considering how to construct the intermediate ceiling in our single-family house. According to the structural engineering, wooden beams measuring 10x24 cm will be used as ceiling joists between the ground floor and the upper floor. For aesthetic reasons, we could leave these visible, cover them from above and build up the floor height (planned are 40 mm impact sound insulation, 8 cm rigid foam, 6-6.5 cm heated screed, and tiles/laminate). We need a certain height to incorporate the installation pipes, which would otherwise disappear between the ceiling joists, such as water, wastewater, and ventilation pipes. However, we have some concerns regarding sound insulation (I believe this is called impact sound insulation). We are concerned about the noise heard downstairs when, for example, the children are playing upstairs and blocks are being thrown around, the Duplo train rattles on the floor, etc. Since the living room will be below the children's rooms, we could use a classic method by insulating between the beams, for example with 200 mm spring wool, covering it from below with drywall, and instead of about 20 cm, have only 15 cm floor build-up on the upper floor.
What do you think about this? Any other/better suggestions? Can the architect calculate what is more sound-absorbing?
