Abstract:
For insulated wall panels, a common practice is to connect the two concrete wythes with a solid concrete block through the insulation at the corbel location. The resulting thermal bridge significantly reduces the energy efficiency of the wall panel. Depending on the climate and building use, the accumulation of moisture on the surfaces can lead to degradation of indoor air quality or the appearance of the panel. These effects are the main reasons for the research summarized in this article.
