ABSTRACT OF THE DISCLOSURE The invention concerns the use of pressure plates made of non-electrically conductive material of low thermal conductivity in a curtain wall which covers the exterior face of a building structure. These pressure plates serve to attach panels, such as window panes or the like, to a metallic (for example, alumi- num) structural framework and to attach thereon metallic (for example copper) exterior trim profiles. The non-conductive pressure plates act as separators between the exterior trim profiles and the structural framework to avoid electrochemical corrosion which would otherwise occur if these two metallic elements were of different metals and in direct contact. The low thermal conductivity of the pressure plates serves as a thermal barrier to limit heat flow from the interior to the exterior in the winter, and vice versa in the summer.
