Sound Insulation of Façade Element with Triple IGU

Sound insulation design for structural glazed façade is an important task in environmental noise control, as increased continuously repeated a significant factor impacting on people’s well-being and associated with negative impact their health. For façades, addition to sound insulation, requirements safe use high energy efficiency are also usually raised, which partly determine the composition of glazing: triple insulating glass unit (IGU) inner safety laminated sheet. Therefore, aim research was investigate sealed structure IGU effect thickness ordinary glasses, position IGU, gas cavities, mass frame level glazing. Experimental measurements index investigated elements various constructions were performed acoustic reverberation chamber according standard procedures. The result study indicated that second inefficient, highest indicators achieved by increasing thicknesses external sheet cavity; has only little
