Thermal Performance of LSF Wall Systems with Vacuum Insulation Panels

Lightweight Steel Frames (LSF) in building construction are becoming more popular due to their fast, clean, and flexible constructability. Typical LSF wall panels made of cold-formed thin-walled steel lipped channel studs with plasterboard linings. Due the high thermal conductivity steel, these components must be well engineered covered against unintended bridges. Therefore, it is essential investigate heat transfer different configurations reduce loss through walls by lowering transmittance, which would ultimately minimise energy consumption buildings. The effect novel insulation material, Vacuum Insulation Panels (VIP), position on configuration, Oriented Strand Board (OSB) plasterboard’s transmittance were investigated numerical analysis. A total 56 112 finite element models analysed compared minimum U-value requirements UK regulations. Numerical model results exhibited that using plasterboards instead OSB has no considerable walls. However, 77% (4 times) reduction was introducing 20 mm VIP. Moreover, VIP negligible. Based results, optimum proposed highlighting methods. Additionally, this study, literature, seeks identify other areas additional research can conducted achieve desired efficiency buildings systems.
