When it is desired to reduce noise by the means of an acoustic enclosure (soundproofing hood), or of a(n acoustic) partition or to protect people (from noise) by the means of a cabin (for soundproofing or soundproofed), or to limit the propagation of noise through an acoustic screen (which is sometimes referred to as a noise barrier), ITS offers a wide range of metallic acoustic door sets for many applications of soundproofing / sound insulation relating to the protection of workers against noise, the preservation of the acoustic environment, the limitation of noise emissions in the energy sector, to testing rooms acoustics.

Quality metallic acoustic door sets contribute to the acoustic comfort in buildings in an important manner.

Range of applications

  • creating a sound reduction or a sound insulation by integration either in a (metallic) construction of an enclosure (hood), in a wall, in a partition (between 2 rooms or between a premise and outside) for industry, for buildings (namely: machinery premises), for environment or in an acoustic screen (indoor or outdoor)

Benefits

  • excellent technical characteristics and robustness (compatible with a high traffic of people and equipment for intensive use)
  • ease of implementation
  • high adaptability of acoustic performance
  • wide range of possible applications (related technical performances on request)

Presentation

  • metal frame with powder coated steel as standard (for aluminum siding or stainless steel: on request) to ensure rapid installation
  • wing(s) with metallic double shell sidings and peripheral gaskets to ensure a good seal to noise (perfect mechanical strength over time)
  • coated steel sidings as standard (for aluminum siding or stainless steel: on request)
  • standard filling made of medium density glass wool
  • thickness, filling, finishes tailored to the desired performance

Construction

  • steel parts (frame and wing) assembled by electric welding
