• Resumen

  • Lightweight steel-framed (LSF) constructive system has become increasingly popular both in new buildings and in refurbishments. Due to LSF buildings usual low mass and rigid connections between the outer and the inner sheathing of the walls, some acoustic performance drawbacks can emerge. In this work, the influence of the steel frame in sound insulation performance of LSF façade walls is studied. For this purpose, several LSF walls types are assessed, namely cold, warm and hybrid constructions. The assessment of the thermal behaviour and sound insulation is performed using Sharp model with some modifications.
