Project Description
AECOSILENT SPECIAL 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 SPECIAL designed as floor product is made up of a ELT rubber mat (50 Kg/m3 density, 2 mm thickness) coupled with a polyester fibre layer (30-50 Kg/m3 density, 6 mm thickness). The characteristics of hardness, treading, resistance to compression and abrasion, crushproof over
time and the elastic module typical of the upper layer are such to protect the material of the lower layer. Easy to use, AECOSILENT SPECIAL 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.
