Doors and windows have always been at the intersection of various technologies and architectural processes that evolved in parallel and often intertwined. Last century’s breakthroughs in terms of glass and frame technologies transformed glass doors and windows into powerful and efficient devices to control light, solar heat, ventilation and vision as well as important spatial […]

Insulated glazing units with gas filled cavities are commonplace in the United States. Climatic pressures should be considered to assess “pillowing” in flat units and the utilization of glass and edge silicone seals in curved and small units. However, the only codified values for climatic loads parameters are presented in the DIN 18008 standard; derived […]

Demands for improved energy conservation of windows and glazing and for solar shading systems installed in the cavity between glass panes mean that the cavity in insulating glass units have to be increased. However, there are tight physical constraints because larger cavities lead to greater climatic stresses of the glass panes and edge seal and […]

Laminated glass is often modeled with one of various effective thickness models to simplify analysis. Effective models are intended to be limited to linear deformations however they are often employed in general glazing applications, such as windows, which typically perform nonlinearly. Consequential, window designs with laminated glass modeled with effective thickness models do not adequately […]

The need for higher transparency in façades has led to the development of jumbo sized glass. Until now, the almost jointless appearance of large-scale glazing could only be reached with laminated safety glass. However, due to the more stringent energy efficiency requirements imposed to buildings, efforts have been initiated by manufacturers to propose transparent insulating […]

Since A.Zoller has proposed the idea of vacuum glass in 1913, vacuum glass technology become more and more mature from the last 100 years. This paper is focused on the main advantages of vacuum glass comparing the characteristics such as sound insulation, thermal transmission and anti-condensation with insulated glass based on the application area of […]

The development of windows and insert unit constructions is essentially driven by architectural trends, statutory energy efficiency specifications, the growing sustainability culture, demands for optimised cost efficiency and the increasing requirements for comfortable living. At first glance, the ongoing architectural trend towards more transparency and narrow profile face widths with concealed fittings is at odds […]

The Vacuum Insulating Glazing (VIG) is a highly thermally insulating window that is thin in profile, light weight, and has a potential lower limit in thermal conductance outperforms existing insulating glass window technologies. Since the University of Sydney VIG invention reported in the early 1990’s, numerous research efforts around the world have led to a […]

The Vacuum Insulated Glazing (VIG) is a thin, light weight, highly thermally insulating window technology that has now a commercial lifetime of over 20 years. Much of the performance of the VIG has been well documented in the scientific literature. Nevertheless, in the last decade it has become clear that the thermo-mechanical performance of the […]

Insulated glass (IG) manufacturing is in a change. The product turned from a technology to a commodity. Internationally qualification on the shop floor is decreasing. And on the one hand the demanded high quality in spec regarding gas filling and tightness as well as lifetime are even more increasing – at the same time pricing […]
