Project Description

AECOSILENT OVER

Technical Data Sheet

Specifications

AECOSILENT OVER is proposed in the market as an example of accomplished synthesis between environment, technology and innovation. The creation of a product with high performances through the use of recycled materials is a challenging project implemented through new technologies. AECOSILENT OVER is designed as floor product made up of a ELT rubber mat (750 Kg/m3 density, 3 mm thickness) coupled with a polyurethane agglomerate layer (90 Kg/m3 density, 5 mm thickness). The characteristics of hardness, treading, resistance to compression and abrasion,

crushproof over time and the elastic module typical of the upper layer (ISOLNOISE AE) are such to protect either the material of the lower layer than to guarantee the high soundproofing capacity. Easy to use, AECOSILENT OVER is equipped with side overlapping selvage so to avoid that imperfections during laying could compromise even only slightly the final result. AECOSILENT OVER, provides results in line with the promised performances.

Generic purpose

AECOSILENT UNDER is used as decupling elastic-resilient mat for the creation of floating floors to reduce the impact sound noises in buildings with any intended purpose, so to comply with the law requirements.

Applications

It is efficiently used in any kind of floors, over the screed.
