Sound Insulation Properties of the Facade Elements - The Influence of Filling Cavities of Facade Elements on the Values of Laboratory Airborne Sound Insulation

The paper is focused on the issues of sound insulation properties of the facade elements which are currently applied mainly at industrial hall buildings. Requirements for the sound insulation properties of these buildings are requested not only from users themselves, but also from residents of surrounding objects, who are often disturbed by operation of the halls. In the paper are presented outcomes from laboratory measurements of the specific samples of external cladding. These measurements were performed by the mutual cooperation between the laboratory of the Brno University of Technology and the firm of civil engineering practice, which develops and produces these constructions. Presented data are focused particularly on the influence of filling cavities of facade elements just with regard to the sound insulation properties, i.e. the values of laboratory airborne sound insulation.
