Enabling Crystal Clear Façades

Interest to include glass to façades has always been present due to its transparency enabling interaction between indoor and outdoor. Major advances in technology have enabled fully glazed sustainable designs providing the demanded aesthetic, whilst respecting occupant benefits such as daylight and energy efficiency systems. This explains the growing interest for increased glass in facades in commercial buildings. The use of bulky frames limiting the transparency of a façade can be minimized through adapted fixation systems including structural glazing designs. Yet even these have their limitations since the adhesive used for the bonding, the weathersealing or the secondary sealing of insulating glass units, are not necessarily both transparent and durable.
