A structural glazing system can be used to construct visually impressive all glass façades. The system offers the designer a wide and diverse range of profiles that will provide structural integrity, weather performance, thermal enhancement and importantly can only be seen on the inside of the building. Its classic visual appearance offers the designer a continuous and expansive external glass face to the façade uninterrupted by external face fixed cover caps. The system is further complemented by the option of introducing concealed frameless top hung casement windows.
