Anyone glancing through a wrought-iron window in a historic building, castle or church will immediately notice what a difference float glass technology has made. You can look right through the glass without any optical distortion. Grenzebach and CNUD EFCO have been shaping the story of float glass technology from the outset. Our wealth of experience benefits our customers all around the world.

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.

“Glass is one of the world’s oldest materials and has achieved a quantum leap thanks to float glass technology. We provide end-to-end support to float glass manufacturers and I’m always impressed each time I walk down a production line. And that really motivates us as a team to break the mold and make the technology even better for our customers.”
