THE SURFACE OF THE MATERIAL
The resilient underlay by Eterno Ivica guarantees acoustic performances.
The test is specific for resilient underlays and is performed on a sample of size 200x200 mm.
The choice of the shape of the contatc surface of the resilient underlay, with the underlying screed, influences the performance.
The wavy and punctiform surfaces, compared to the flat ones, are more effective and improve the acoustic comfort.
