At sedak, tempered glass shows what it can really do
Glass tempering means treating basic glass products, up to 20m (787in) long, to create heat-strengthened or fully tempered glass, which, after firing, can be further processed to form laminated safety glass.
sedak has one of the world’s largest glass tempering installations with a 75m (246ft) long furnace for processing flat glass to create heat-strengthened or fully tempered glass.
In 2017, sedak expands its range of capabilities and starts operating a new tempering furnace for glass up to 16.5m. The so-called convection furnace allows the glass manufacturer to temper pre-coated glass. That leap in technology offer clients not only time but also cost efficiency.
We also set standards in terms of quality control of heat-strengthened and fully tempered glass. If required by a customer, we can test every fully tempered pane in our heat-soak chamber for the nickel sulfide inclusions that can cause spontaneous failure. The result of the heat-soak test is a standardized, high-quality, heat-soak-tested, fully tempered glass.
