Acoustic insulation panel with 2 absorbing faces

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 acoustic insulation panels with 2 absorbing faces 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 on the other side
the acoustic insulation panels with 2 absorbing faces are particularly appropriate when one is looking for a simple wall effect

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 separating workshop halls or soundproofing adjacent workstations (boxes of welding, grinding, hammering, ...) or the realization of partitions in an acoustic enclosure like a soundproofed container for energy production, a soundproofed test bench or the completion of splitters for rectangular silencers, ...

Presentation

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)

metallic acoustic insulation panel
(absorbing face)

Construction

each module comes in the form of a freestanding box

Standard constitution

a perforated steel sheet, 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). Possibility of a filling including an intermediate galvanized steel sheet
width of the modules: 1000 mm

Anti-corrosion

for typical applications, the acoustic insulation panels with 2 absorbing faces 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 acoustic insulation panels with 2 absorbing faces 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 acoustic insulation panels with 2 absorbing faces 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

E (mm)	filling RW R (m2 . K / W)	filling PO R (m2 . K / W)
60	1,71	1,64
80	2,30	2,20
100	2,85	2,75

Acoustic performance

sound reduction index according to the standards NF EN ISO 140-3 Acoustics - Measurement of sound insulation in buildings and of building elements - Part 3: laboratory measurement of airborne sound insulation of building elements and EN NF 717-1 Rating of sound insulation in buildings and of building elements Part 1: airborne sound insulation

E (mm)	filling RW Rw (dB)	filling PO Rw (dB)
60	32	32
