The AECO ZERO soundproof panels, similar to the SOUND AE ZERO ones, have been designed and manufactured to improve and reduce the echo period. The pyramidal AECO ZERO panel, thanks to its angular structure tripling the absorbent surface, reaches high acoustic absorption levels, with remarkable results on the medium and high frequencies. It can be in expanded polyurethane or in expanded Basotect from BASF in melamine resin. The Dimpled AECO ZERO, in flexible polyurethane glue polyester based, is particularly recommended for the acoustic improvement of industrial environments, for the soundproof covering of air drains and shooting ranges and in the internal covering of carters, encapsulations, silencers, acoustic rooms and ventilation machineries. Lightness, convenience and easy application are amongst the most relevant characteristics of the AECO ZERO panels, available in various dimensions and compatible with the architecture of all the interiors.
