"Structural glazing glass has been driven for years by the constant development and increasing demands in facade construction. Five aspects need to be highlighted in particular. Glass becomes thinner - reduced glass thicknesses, combined with more differentiated, high-performance intermediate layers, allow savings in weight and material. Glass is getting bigger - the trend towards larger formats is unbroken and allows possibilities well beyond the usual jumbo format of 6.0 x 3.2 m2. Glass is bent - today, free facade shapes can be continued over the glass surfaces without breakage. Cold forming by deliberately pressing a glass package onto the substructure or hot forming in the furnace with extreme curvatures is possible and expands latitude.
Glass becomes more functional - additional properties lend new functions. In this way, the heat balance and solar utilisation can be controlled by switchable transmission regulation. Likewise, façade surfaces are increasingly and transparently used to generate energy at the place of consumption. After all, media glazing is available as displays or touchscreens. Glass is becoming safer - new layer sequences, joining possibilities and material developments allow greater safety even in extreme events, such as fires, hurricanes or burglaries and explosions. In addition, the design methods are refined and allow a more precise quantification of impacts such as impact or permanent loads that lead to material aging. This will provide more possibilities - especially by combining several advanced ideas - which can serve as a source of inspiration for new applications and designs".
