Werner Wagner, Sika Services AG

Gas-filled insulating glass units in windows and capped-system curtain walls is state-of-the-art technology.

The development of other warm edge spacers and new silicone secondary sealants gives insulating glass manufacturers more options to produce gas-filled insulating glass units with UV resistant edge seals for the use in structural glazing facades. Gas loss rates as low as 0.2 % per annum ensure a service life of more than 20 years. Nevertheless all this requests highest product and production quality and precise calculation of the sealant height considering both wind loads and climatic loads.
