Rigid mineral wool acoustic insulation panel for walls FRATELLI RE
REPI SOUND

The REPI SOUND panels are metallic panels with insulation made of mineral wool fit for the realisation of Roofs Coverings, Walls, Internal Division of industrial and civil building
The REPI SOUND panels are constituted of two trapezoidal or microgrooved metallic supports with interposed insulation of oriented fibre mineral wool which is arranged in fillets perpendicularly to the two metallic supports.

METAL SUPPORT:
The REPI SOUND panels are made of two trapezoidal, microgrooved or flat metallic supports obtained by cold-process profiling the sheet coils.
The materials which are used are:
- Galvanized Steel
- Prepainted Galvanized Steel
- Stainless Steel
- Natural Aluminium
- Prepainted Aluminium
- Copper

INSULATION:
The insulation is made of oriented fibre mineral wool which is arranged in fillets perpendicularly to the two metallic supports. The thickness of the insulation may vary from a minimum of 40 mm to a maximum of 300 mm with a density from 75 to 150 kg/cu.m.

PERFORMANCE AND TECHNICAL ASPECTS
The REPI SOUND panels belong to the category of fire-proof products and soundproofing and soundabsorbent products. The REPI SOUND panel obtains the soundabsorbent power thanks to its typical Perforated Sheet exposed to noise. Acoustic tests have attributed to the REPI SOUND panels values of RW equal to 32dB, 33dB, 35dB, which face the problems concerning noise reduction. In order to increase the soundproofing power, it is possible to produce a monolithic panel supplied with triple sheet, that is to say with a thin metallic sheet between two insulating layers.
