The acoustic doors with high sound insulation have a noise abatement Rw, measured according to ISO 717-1, equal to 50 dB. They are built from a robust metal frame containing inside a high-efficiency sound-deadening assembly on which multiple gaskets are housed. The hinges are adjustable for optimal registration.
There are different sound-absorbing, sound-insulating and damping materials to avoid the propagation of sound through sheet metal vibrations.
The acoustic grilles, of a special type to guarantee an excellent noise reduction, are made of galvanized sheet. A sound insulation measured according to ISO 717-1 Rw> 30 dB has been detected.
