What other tests are exterior wall mock-ups subjected to?
Many curtain wall mock-ups are subjected to vertical and horizontal interstory movement. Simulated floor slab conditions are mechanically fastened to permit hydraulic jacking side to side and up and down. The purpose of these movements is to simulate wind induced movement of multi-story buildings and live load conditions. Horizontal movements due to seismic events are performed on occasion as well. Thermal cycling and condensation evaluations are also performed frequently on curtain wall systems. Stud wall chambers covered with foam insulating board are erected on the exterior of the mock-up. The curtain wall mock-up is subjected to alternating hot and cold cycles maintained for two hours per cycle. Window washer anchorage load tests, supplemental water resistance following sealant removal, negative load sealant bonding tests are performed when specified.
