No, that works well. Not a belief, but recently did 120sqm myself. For that, there are extra short staple needles.I believe that with 2 cm PIR/PUR insulation with aluminum facing, it gets a bit tight with staples.
Yep. PUR downstairs to the basement and upstairs whatever is most effective for impact sound insulation at 20mm.But as long as the ground floor & attic are in the same "climate zone" regarding underfloor heating, then it is not necessary to install expensive PUR in the attic – you basically do not need insulation there if the rooms are relatively evenly climate-controlled.
