The invention relates to a multilayer wall covering comprising: (a) a support layer formed by an organic polymer foam having an open porosity of between 0.50 and 0.995 or by a non-woven fabric made from viscose fibres having a mass per unit area of between 150 g/m2 and 500 g/m2; (b) a surface layer formed by a glass textile, having a static air flow resistivity, measured in accordance with international standard ISO 9053, of between 105 N.s.m4 and 106 N.s.m4; and (c) at the interface between the support layer (1) and the surface layer (b), a non-continuous adhesive layer having a mass per unit area of between 17 and 60 g/m2. The invention also relates to the use of such a covering for improving both the acoustic and thermal comfort of a room and to two methods for the production thereof. |
