The Crystal, Newham

摘要

While externally it is all glass, only 39 per cent of the Crystal's envelope is transparent. The remainder consists of glazed insulated metal cassettes with the DGU bonded to its carrier frame. All panels use high-performance glass. The envelope comprises structural steel mullions and transoms of varying cross-sections. Toggled-fixed DGU cladding panels are mounted on the steel sections. The design focused on the DGU joint as a potential weak spot. The joint has a high-performance gasket and quadruple cavity external silicon band-mounted outside the toggle to maintain air barriers.
