New Lightweight Gypsum Composites for the Construction of LSF Walls: A Study of Thermal Behavior

This study analyses the thermal behaviour of a new lightweight gypsum material, developed in line with the principles of the circular economy, which has reduced the thermal conductivity of these compounds by up to 30.4%. Similarly, the contribution of these compounds to the energy efficiency of LSF walls with steel structures in different configurations has been examined, including thermal break strips to mitigate the thermal bridge effect. The thermal resistance of the walls has been analysed using 2D numerical simulations, which have demonstrated the positive impact of these various solutions on improving the energy efficiency of LSF systems.
