The objects of research are translucent elements in curtain wall systems, which are common modern architectural and structural solutions. Method. To determine the stress-strain state of a translucent element as part of curtain wall systems, different calculation methods are applied to calculate insulating glass units under full wind load. These methods are based on recommendations from regulatory documents, Navier Solution and numerical experiments in Mepla ISO program and ANSYS software package. In calculations, insulating glass units have different values of linear dimensions, glass thickness and air gaps. The deformation characteristics of a two-component sealant are determined by testing the material in an experimental setup. Results. Based on the results of the work, the convergence of the methods with each other is considered, and the glass unit with the smallest deformation values in the outer glass from the action of wind loads is determined.
