Be Quiety,
Be Your Standard.
Certification for outstanding floor noise reduction,
proven by AI-based all-unit measurement data
QUIETY Standard measures every unit at each construction stage to verify insulation performance,
and certifies complexes whose quality is proven.
It is a private certification run by Metainnotech and does not replace the statutory performance inspection.

through stage-by-stage measurement,
and manages complex-wide variation by measuring every unit.
