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 sound absorbing panels 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.
Range of applications
- creating a sound reduction or a sound insulation by the (metallic) construction of an enclosure (hood), of a partition, of a screen, with a limitation of the amplification of noise level on one side of the acoustic protection and/or on the other side
Benefits
- excellent technical characteristics and robustness
- ease of implementation (vertical or horizontal or oblique using, easy assembly/disassembly)
- high adaptability of acoustic performance
- wide range of possible applications such as enclosures (hoods) for varied noisy equipment including machine tools (punching presses, presses, ...), machining centers, rotary presses, ..., the partition of noisy areas in a workshop, the production of workshop screens, the achievement of booths for the acoustic test of components for production lines in a noisy environment, the soundproofing of thermal and cooling production equipment, the realization of outdoor noise barriers for air conditioning equipment or for processes of any kind, the realization of acoustical enclosures for engines, compressors, fans, the construction of soundproofed test benches, ...
Presentation
- single or double skin metal panel, modular, ensuring on the one hand a very good seal to noise, and also an easy disassembly and reassembly (perfect mechanical strength over time)
- thickness, filling (generally mineral wool or polyester wool with possibility of intermediate galvanized steel sheet), finishes tailored to the desired performance
- powder coated steel siding, many colors as standard (other colors, or aluminum or stainless steel siding: on request)

Construction
- each module comes in the form of a freestanding box
Standard constitution
- non perforated steel sheet shell, thickness according to performance requirements, with powder coating (other finishes available on request)
- a filling made of high density rock wool
- a perforated steel sheet, thickness according to performance requirements, with powder coating (other finishes available on request).Note: possibility of a reinforced siding (non perforated steel sheet according to performance requirements).Note: possibility of a filling including an intermediate galvanized steel sheet
- width of the modules: 1000 mm
Anti-corrosion
- for typical applications, the sound absorbing panels are protected by a multilayer coating system in accordance with ISO 12 944 C2, with high durability (above 15 years).
- for more demanding applications, the sound absorbing panels are protected by a multilayer coating system in accordance with ISO 12944 C4 or even C5 with high durability (above 15 years).
Weather resistance
- indoor or outdoor use in normal environments (other finish for different uses: on request)
- options: composition for special applications (high pressure washing, chemical, pharmaceutical, ...)
Fire behavior (reaction to fire of ingredients according to standard NF F16-101)
- siding:galvanized finish: rating M0;powdercoating finish: rating M1
- filling:rock wool: rating M0;polyester: rating M1
Miscellaneous
- in case of a filling made of rock wool, a glass cloth prevents grinding
- in case of a filling made of polyester, no surface treatment is necessary, the filling being not subject to grinding (due to a surface microfusion) and being not in a position of releasing biopersistent material
- whatever the filling is, the sound absorbing panels contain no element favorable to microbial growth
Thermal performance
- thermal conductivity of rock wool filling (RW): 0.035 W / m / K
- thermal conductivity of polyester filling (PO): 0.0365 W / m / K
- thermal resistance R of the filling of thickness E
