The cutting-edge building structure envelops are composite layers of metals and insulating media that enable best features of strength, insulation as well as corrosion resistance. Thee are designed with multiple metal layers inside which core materials are sandwiched. As compared to conventional wall and ceiling construction, the use of these sandwich composite panels enables peak levels of cost-effectiveness as well as sustainability in construction projects. The use of these alternate panels makes it possible to gain an ideal balance between the aesthetic as well as functional features of a structure and thus better benefits in both are assured. These provide a wide range of advantages that makes them a highly popular choice for contractors and engineers. Use of sandwich composite panels in wall and ceiling cladding Sustainability and cost-effectiveness are two major factors that determine the overall approach to modern-age infrastructure development. Every process, ma
