The invention relates to a self-adhesive wall covering comprising a glass textile with a closed structure, consisting of glass fibers and of a water-permeable polymer binder, and an adhesive coating comprising both a pressure-sensitive adhesive (PSA) and a water-activable latent adhesive. The definitive attachment to the wall of this repositionable self-adhesive covering takes place, after hanging, by applying one or more coats of water-based paint.

Self-adhesive water-activable glass web

A multilayer sound-absorbing covering includes (a) a support layer made of an organic polymer foam having an open porosity between 0.50 and 0.995, (b) a surface layer formed by a glass textile, having a static air flow resistance, measured according to the standard ISO 9053, between 105 N&#xb7;s&#xb7;m-4 and 106 N&#xb7;s&#xb7;m-4, (c) at the interface between the support layer (a) and the surface layer (b), a discontinuous adhesive layer having a surface density between 17 and 60 g/m. There is also provided a process for manufacturing such a covering and the use of such a covering for improving the acoustic comfort of a room or of a building.

Acoustic absorbent wall coating

A multilayer sound-absorbing covering includes (a) a support layer made of a nonwoven based on organic fibers having a tranverse multilobal cross section, (b) a surface layer formed by a glass textile, having a static air flow resistance, measured according to the standard ISO 9053, between 10N&#xb7;s&#xb7;mand 10N&#xb7;s&#xb7;m, (c) at the interface between the support layer (a) and the surface layer (b), a discontinuous adhesive layer having a surface density between 17 and 60 g/m. There is also provided a process for manufacturing such a covering and to the use of such a covering for improving the acoustic comfort of a room or of a building.
