The production process of BENGglas
The vacuum glass production line has a length of 400 meters and annually produces 120,000 square
metres of tempered vacuum insulating glass annually.
In upgrading a monumental building in Arnhem, BENGglas fitted the facade entirely with tempered vacuum glass.
The contractor for the project – Achterberg Schilders – points out a number of important aspects of vacuum glass. He mentions the good insulation value (U=0.4), the manageability and the light weight of the glass. Installation of this glass is done in the same way as traditional insulation glass.
What makes vacuum glass particularly suitable for the renovation market is that it is very thin. With a thickness from of only 6.3 mm, it almost always fits into existing window frames and does not need to be replaced.
Residents noticed a huge difference compared to traditional double glazing. The motive for switching to vacuum glass was the improved insulation value, but they are also very enthusiastic about the increased living comfort. They feel no ‘draft’ and noises from outside are muffled.
The entire project only took two days. Installation of the glass has been carried out by one of BENGglas Dutch partners.
BENGglas is the only tempered vacuum insulating glass in the world!
Tempered glass offerss several advantages:
The ball drop test is used to test the mechanical strength of the glass.
