For soundproofing? Doesn’t one negate that again with wood-angle-screw-floor?
Not for soundproofing, it’s on the ground floor; it’s meant to let the floor flex (good for the joints). And it works exactly as I had planned ;-) But it’s probably just a big coincidence since I couldn’t calculate THAT at all but only roughly estimated it (beam cross-section and spacing, counter battening, OSB, impact sound insulation + parquet, etc.)
