FAQ
(1) What performance tests can be completed with this system?
This system can evaluate key curtain wall properties including air permeability, water tightness, wind load resistance, and in-plane deformation performance. These tests help verify whether curtain wall assemblies meet design requirements and applicable building standards before installation.
(2) What types of curtain walls can be tested?
The system is suitable for various curtain wall structures, including unitized, stick-built, glass, aluminum alloy, steel-framed, and composite façade systems. The configuration can be adjusted according to specimen size and laboratory testing requirements.
(3) How does the system evaluate water tightness?
