Enjoy the appeal of glass

Sand, lime, dolomite and soda are all used to make the exceptional material that is glass. The ingredients melt at a temperature of 1,400 degrees Celsius, or 2,552 Fahrenheit and turn into glass. The basis is a liquid that remains transparent when it solidifies and is very stable. The float glass method is the most successful in the history of flat glass production, which goes back thousands of years.
Grenzebach and CNUD EFCO have been supplying production and processing machinery for industrial float glass from the very beginning. Since the 1990s, we’ve been technology pioneers in this sector.

Today, way more than half the panels of glass fitted in buildings are based on Grenzebach technology and/or produced by CNUD EFCO.

There’s no end to the variety of ways glass is used. But regardless of whether it’s architectural glass, automotive glass, patterned glass, thin glass, wired glass or customized glass, special machinery is required to make, fabricate and convey it. With over 300 systems installed internationally, Grenzebach and CNUD EFCO are hugely experienced in the sector.
