Abstract

Highlights: Mandatory tests are inadequate to evaluate lifetime performance of façade systems. Full-scale tests can provide realistic information about system performance. Stick system might be fragile than panel system under similar extreme conditions. Thermal cycling test is significant for lifetime performance evaluation. Air and water infiltration are the most common problems in curtain wall systems. Abstract: 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.
