The invention relates to an adhesive insulating system (3) that is non-destructively removable, e.g. for repair purposes, for sound insulation of partition walls (1), particularly in motor vehicles. Between the foundation and the overlying layers of the insulating system (3) a layer (2) of a highly under-cross-linked polyurethane material or a special bitumen mixture is applied that has a strong adhesive effect and thus enables a force-locked connection to be made between the foundation (1) and the insulating system (3). To ensure that the desired flexibility is obtained together with unchanged acoustic effectiveness even when a carpet (8) is laid on the insulating system (3) or its heavy layer (6), according to the invention a decoupler (7) of soft elastic, predominantly open-pored material is arranged between the carpet (8) and the heavy layer (6). Surprisingly, along with the desired flexibility, the acoustic effect is further improved.

An adhesive, non-destructively removable insulation system for sound insulation of partition walls comprising an adhesive coating disposed between a partition wall and a spring having sound dampening properties, said adhesive coating providing releasable adherence of said spring to said partition wall, and an acoustic decoupling layer, disposed above said spring, providing acoustical decoupling between said insulation system and a covering disposed over said decoupling layer.
