Semi-Unitized Structural Glazing
A semi-unitized curtain wall glazing system is a type of structural glazing where the primary structural framing components are erected individually as an erector set. In this set, the vertical mullions are attached first to the floor slabs and the horizontals are attached to the vertical mullions to resemble a grid. The glass panel and the spandrel, which can be either glass or aluminium are shop glazed and installed into the assembled grid work. The joineries and perimeter sealants are fields installed. The semi-unitized systems are largely anchored to the face of the slab as embedded plates or inserts. The vertical mullions in most semi-unitized glazing systems can span two floors with ease and as a result, provide greater structural efficiency.
Semi-Unitized Structural Glazing is used extensively in skyscrapers, with glass facades a ubiquitous feature in the financial centres of cities across the globe. Strengthened, laminated glass can also be used in floors, roofs and frameless glass walls at home.
