Insulating Glass with inserts for sun and energy control

Frank Schneider, OKALUX GmbH, Germany

Glass has become an indispensable material in today’s architecture and building design. Aside from the insulating capacity, the facade has to fulfil technical functions, such as glare and sun protection. All these parameters have an influence on the reduction of the building’s energy consumption and CO2 emissions. New applications for technical inserts inside the cavity of an Insulating Glass Unit will be discussed in this report. E.g. capillary slabs improve the thermal insulation by stopping the convection. Further improvement can be achieved with fillings of nanoporous Silica-based Aerogel, which prevents convection and conduction. In the future, all possibilities have to be used to enable a maximum performance of the façade with respect to the buildings energy reduction and the users comfort.
