    "limitations": [
      "The declared 80 dB is a flat-sample figure; overlaps have to be conductively joined or each seam becomes the dominant leak",
      "Needs a level substrate for crease-free bonding, and structured surfaces must be smoothed or shielding paint used instead",
      "Metallised coatings degrade with abrasion, moisture and corrosion, and the loss cannot be seen",
      "Conductive: it must be grounded correctly to control low-frequency electric fields and to be safe near wiring"
