The Applied University of Bern (BFH) has researched the use of two component adhesive compounds for the manufacture of windows for more than a decade. BFH developed the idea of using structural sealant glazing (SSG) technology to produce the next generation of wooden windows that allow for a highly automated production and large areas of glazing, and conform to all the current requirements regarding energy efficiency and sound and burglary protection. In cooperation with an industry partner, nolax AG of Sempach-Station, Switzerland, the BFH currently is investigating the replacement of plastic blocks used to fix glazing into the window frame with liquid filler compounds. Today, such blocks are pieces of plastic or hardwood of a predetermined thickness, that are inserted thigh between the insulating glass and the window frame on all four sides. This insertion process requires considerable manual labor and high precision at the assembly line. Also, even small inaccuracies within the glazing's seal edges create stresses that can cause the glass to break while in operation. Thus, the research undertaken investigates if liquid fillers inserted into the space between the glass and the window frame could improve this connection and does allow producers to reduce the labor content of this activity.
