SOUND ABSORBENT PANELS FOR REVERBERATION TIME TREATMENT

Sound absorbent panels for the acoustic adjustment of recording studios, meeting rooms, restaurants etc, where is evident the necessity to reduce the reverberation time “echo effect”.

AECO ZERO PYRAMIDAL (Polyurethane – Melamine Resin)

AECO ZERO Pyramidal is made up of expanded polyurethane, flexible to open cells, made of polyester, 35 kg/m3 density, anthracite colour; temperature resistance: -10°C and + 90°C. Very good for absorbent acoustic insulation, it
also gives a good thermal insulation, with a consequent energy saving.
The AECO ZERO Pyramidal panel, thanks to its angular structure which triple the absorbing surface, allows to reach very high acoustic absorption levels, with very good results on medium high frequencies (500-2000 Hz).

AECO ZERO Pyramidal can be made of expanded Basotect® by BASF, based on melamine resin, pale grey colour.
Product with a high thermal resistance*150°C, it is in class 1 and in case of fire, does not drip and it is not fibrinogen.

AECO ZERO Pyramidal in melamine resin has a very high acoustic absorption, in particular on medium high
frequencies (500-2000 Hz).

AECO ZERO DIMPLED

AECO ZERO Dimpled is made up of flexible polyurethane foam based on polyester, self-extinguishing, not dripping,such as NG35 of anthracite colour. It allows to disperse the very high intensity of the acoustic energy produced in the environment.

AECO ZERO Dimpled is a sound absorbing product widely used for the acoustic restoration of industrial environment,in the sound absorbent coating of air pipes, of shooting ranges, of carters internal coating, encapsulations, silencers,acoustic cabins, ventilation systems, etc.

Whereas is necessary to obtain a very high sound absorbing coefficient, AECO ZERO either Pyramidal and Dimpled can be assembled to the sound insulating barrier AESTARK PLUS.

Light and practical, the AECO ZERO panels are particularly simple to be used and prove to be the ideal solution for the instantaneous acoustic treatment. Available in various sizes, allows to improve the functionality with the architecture of
all interiors.
