      "Interior application on non-heat-absorbing glass only: applied to already-metallised solar-control glass, multiple reflections heat the pane and can crack it or break the edge seals",
      "The cut edge exposes the metal layers and has to be sealed, or the film corrodes inward from the edge",
      "32 dB on the glass does nothing about the frame, the reveal or the wall around it, and the window frame needs separate shielding to keep the path closed",
      "Field arriving through walls, roof or floor is untouched, so a film alone rarely changes a whole-room reading much"
