AECOSILENT UNDER 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 UNDER is designed as floor product made up of a ELT rubber mat (750 Kg/m3 density, 6 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 UNDER is equipped with side overlapping selvage so to avoid that imperfections during laying could compromise even only slightly the final result. AECOSILENT UNDER, provides results in line with the promised performances.
