quality assessment of insulated glass

Defects in IG units

Insulated glass production is characterised by fully automated manufacturing processes. It is possible to achieve objective and in particular continuously 100% quality inspection for all glass at many different stages of production. Single sheets prior to assembly as well as bonded insulation glass units can be inspected precisely with the LineScanner. During the quality assessment of the insulated glass, any optical defects – in special butyl defects, the frame and frame structure – will be detected by the LineScanner exactly and completely.
