Abstract

In recent years, a significant economic effort has been made in the refurbishment and energy improvement of buildings, which should be used to improve their acoustics performance. It is necessary to avoid energy improvement from deteriorating the pre-existing acoustic performance prior to the refurbishment. In this work, an analysis of the acoustic insulation of the façades of enclosures in residential buildings is carried out in which the thermal insulation of the blind part of the façade is improved on the outside without mullions and battens. The most important factor for the improvement of the airborne sound insulation of the blind side of the façade is that the dynamic stiffness of the external thermal cladding is as low as possible, and that the openings are solved with a double asymmetrical glazing and its air cavity is as thick as possible. The obtained results may be useful for all professionals involved in the construction process of building renovation: architects, engineers, developers, manufacturers, etc.
