Hello,
we want to insulate a part of the visible ceiling beams from the ground floor perspective in our new building (2013) and cover them with plasterboard, since we only want the open beam look in the living room and hallway.
Above the beams/floorboards there is, from the upper floor, a 4 cm thick stone wool impact sound insulation, 8 cm rigid foam/styrofoam insulation, 0.2mm construction foil on the insulation/PE edge insulation strips on the walls, underfloor heating for warm water and 6.5 cm screed, plus floor coverings tiles and laminate.
Now the question, the beams are 24 cm high, should they be fully insulated (glass or stone wool) or only partially e.g. 20 cm to work according to the spring/mass principle? We also hope for somewhat more sound insulation by doing this, since the rooms above are the children's rooms and the noise carries through quite a bit when they play, which is probably also due to the cheap laminate that is very loud and transmits sound well despite a 3mm universal impact sound insulation. We then want to switch this off and then cover it with plasterboard,
What about a vapor barrier foil? Does one have to be installed and if yes, above or below the insulation? This is to be done in the utility room, guest room and guest bathroom; in the hallway and living room the open beam ceiling is to remain as it is.
Best regards
