Viprotron has developed a new technology for the exit of the furnace, that allows the measurement of the distortion of tempered glass with high precision and unparalleled repeatability. The patented “True Edge Technology” used for this purpose makes it possible to start the measurements right at the glass edges and not just with an offset. This allows the edge kink at the leading and trailing edge to be measured with a high degree of precision. Such exact measurement results are important, especially when tempered glass is further processed into laminated safety glass. But this technology also measures the center areas with high precision, so architects can rely on the documented measurement results with regard to the final aesthetic appearance of the tempered glass, in order to be able to classify the quality of the final façade accurately.
