Production, quality assurance, emissions and health-relevant ingredients are monitored by TÜV SÜD; that certification covers the product, not a site installation.",

    "limitations": [
      "Conductive paint left ungrounded floats at the potential of nearby wiring and can raise the AC electric field in the room rather than lower it",
      "The declared dB applies to a continuous coated sample: windows, doors, sockets and service penetrations are unshielded paths and usually dominate the installed result",
      "Coats have to be continuous and of the declared wet film thickness; thin or patchy application loses several dB with no visible sign",
      "A TÜV SÜD certification of the product is not a measurement of the finished room, and no attenuation figure predicts what a meter will read after installation"
