How do I know for sure that I have received BENGglas®?
Unfortunately, there is a lot of counterfeit glass circulating that is wrongly offered as BENGglas®. However, BENGglas® is the only brand that is manufactured with titanium – for maximum insulation and an exceptionally long lifespan. Moreover, the U-value of BENGglas® is confirmed with independent European test reports, so you always know exactly what you're getting.
Do you want to be sure that you have really received BENGglas®?
Check it easily with our checklist:
- There is always 55 mm between each spacer.
- The flexible metal edge seal is nicely rounded at the corners – this is important for maintaining the vacuum.
- This edge seal is approximately 9 mm high on all sides. Including the absorption strip, it amounts to approximately 13-14 mm.
- The edge seal can have different colors: white, dark red, or light yellow. Never green, dark yellow, or any other color.
