Abstract Modular construction offers clear advantages over traditional building methods, including shorter construction times, reduced on‐site labor, improved quality control, and lighter structural systems. Despite these benefits, concerns remain regarding the thermal and acoustic performance of modular solutions, particularly those based on lightweight steel framing, which are widely used in residential and commercial buildings. This study investigates the thermal and acoustic behavior of steel‐framed modular wall systems, with particular emphasis on airborne sound insulation and heat transfer performance. The adopted methodology follows relevant ISO standards, notably ISO 10140 for acoustic testing, as well as applicable national technical regulations. The baseline analysis compares conventional modular wall configurations with optimized solutions incorporating commercially available products, such as acoustic studs, high‐performance boards, and enhanced thermo‐acoustic insulation layers. Key performance indicators, including sound reduction (R) and thermal transmittance (U), are evaluated through a comprehensive assessment framework. The results aim to identify improvement strategies that can be readily integrated into existing industrial manufacturing processes without compromising system efficiency or modularity. Overall, this work seeks to provide practical guidance for the development of modular construction systems with improved thermal and acoustic comfort, supporting the broader adoption of more effective and sustainable building solutions.
