Description

Insulation system against impact sound noises made up of one layer of polyester fibre (35-50 kg/m³ density) and a second one made up of natural and synthetic elastomeric compounds, coming from the recycling of E.L.T. (end of life tyres) bound by mass-polymerized polyurethane (950 kg/m³ density).

USE

Acoustic insulation from impact sound noise obtained by carrying out a floating floor over a suitable de-coupling layer made up of an elastic-resilient material after the realization of lightened levelling screed. The elastic element at issue is made up of an elastomeric granules mat bound by mass-polymerized polyurethane resins of 950 kg/m³ density, 2 mm thickness, coupled with a layer of polyester fibre of 35-50 kg/m³ density, 6 mm thickness, with an attenuation rating index of the impact sound pressure level of Lw = 32 dB and absolute dynamic rigidity equal to 13 MN/m³ . The AESSE RUBBER system by VALLI ZABBAN, thanks to the edges with overlapping selvage, does not require any further jointing elements between the rolls, if these are carefully laid perfectly adjacent to one another; it only remains necessary the external connection with the vertical partitions, using ISOLBAEND V, for the construction of the floating floor tank
