摘要 |
<p>The invention relates to a multilayer acoustic absorbent coating comprising (a) a supporting layer consisting of an organic polymer foam having an open porosity of between 0.50 and 0.995, (b) a surface layer formed by a glass textile material, having a static resistance to airflow of between 105 N.s.m-4 and 106 N.s.m-4, measured according to the ISO standard 9053, and (c) a discontinuous adhesive layer having a mass per unit area of between 17 and 60 g/m2, at the interface between the supporting layer (a) and the surface layer (b). The invention also relates to a method for producing such a coating and to the use of such a coating for improving the acoustic comfort of a room or a building.</p> |
