RENOVATION

A minor impact sound insulation can cause essential problems in the house and commercial building. The impact sound insulation shows the quality of the ceiling system in relation to structure borne soundstimulations which arise by walking or other user noise on floors (e.g. moving chairs). The sound energy, which is induced in the component, is partly quickly transferred in heat and partly spread over many components and thus finds its way into adjacent rooms in kind of airbone sound. Consequently, the system can be judged as total system which shows next to the „direct sound way“ about the ceiling also sound byways that develop especially about the flanking components.

A “floating floor screed construction” can help considerably to reduce the structure-borne sound transmission from the screed plate to the ceilings below and the flanking components – effectively by about 10 to 40 dB.

A good working “floating floor screed construction“ can be reached by means of a complete acoustic acting separation between the ceiling and the flanking walls to the screed floor. This separation is made by an intermediate layer consisting of very elastic components with an appropriate deflection amount.

Structure-borne sound bridges between the screed plate and the ceiling or walls can impair the impact sound considerably. Therefore, it is of increased significance to avoid structure-borne sound bridges during the screed. This means at the borders edge stripes have to be fitted carefully. The ceiling has to be covered completely with an impact sound insulation and at the borders edge stripes have to be fitted. In edges of rooms, on doors, in bathtubs, showers and at pipe penetrations special attention and control is required to avoid the appearance of structure-borne sound bridges.

The acoustic renovation makes it possible to locate and eliminate structure-borne sound bridges. This method allows a renovation without replacing the screed construction. The reconstruction last only one day, thus only leading to less interference of the living and working rooms.

The renovation of an old building requires a very careful and predictive planning. During the renovation phase technical details are often considered insufficiently which leads to sustainable structural damages.

We support you in the renovation planning so that sound, heat and humidity insulation are not left to chance. By a professional construction considerable costs can often be avoided.

By the selective use of advanced measuring techniques we are able to appraise humidity and mould damages. Any renovation measure must be successful for the long term – a pure optical lamination is not the right way.

Constructive problems have to be alleviated or solved in order to allow an comfortable use of room and working rooms
