Lifetime performance evaluation of stick and panel curtain wall systems by full-scale testing

This study presents stick and panel curtain wall systems’ lifetime performance comparison by conducting full-scale testing according to a proposed test method. The procedure is based on Turkish standards and supported by CWCT. Besides weather tightness, wind and seismic resistance tests, thermal cycling are included to the procedure in two-stages between −10 °C and +50 °C considering temperatures in 20 years in Istanbul. Results showed that stick system might be more fragile than panel system under the same conditions. This study is thought to be a leading work in lifetime performance assessment of such curtain wall types by considering specific local conditions.
