We see the world through glass

Float glass production with Grenzebach and CNUD EFCO GFT

Profound knowledge and decades of experience deliver their full potential: Together, Grenzebach creates added value for the international glass industry. Consolidated expertise in flat glass production means innovative technologies, which are optimized through digitalization and energy-efficient operation for the future.

Go directly to the solutions

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.”

Hot to cold

Our mission:

Grenzebach’s mission is to cover the journey glass takes from hot to cold. We offer a one-stop solution that encompasses the tin bath to the annealing lehr all the way to the cold end, transporting the finished product to the warehouse. Why not make use of this unique factor?

Technology & equipment

Tin bath

The tin bath is the heart of every float glass production line; it is a decisive quality factor. Consequently, at Grenzebach, it is always tailored to each customer’s requirements. Using process simulation, we are able to extract the ultimate in yield and quality.

Drossbox

In the dross box, the glass floating on the tin is lifted out of it for the first time and transferred to the annealing lehr. The trick is to transfer the glass ribbon from a liquid and full-surface support to a roller conveyor.

Annealing lehr

The annealing process is a decisive factor for quality, productivity, and efficiency. With our innovative systems, you can keep it fully under control: the latest technological control applications monitor your process at all times, prevent production losses and help to minimize downtime.

Utilities and central power supply

For a float glass plant to operate reliably and at peak performance, it needs a steady supply of energy and other media like natural gas, electricity, inert gas, tin and much more.

Conveying technology

Our technology conveys glass gently and precisely – even over distances greater than 100 meters or 110 yards. What’s more, our conveying solutions operate smoothly and have long service lives too.

Cutting technology

Cutting technology lies at the heart of the cold end of a float glass production line. Combined with the breaking system, the cutting heads, force-regulated controls and an intelligent optimization system form a superbly efficient unit.

Metrology

As a glass manufacturer, a stable production process is more important than ever these days. Grenzebach’s inspection and measurement procedures stand for advanced control methods and top product quality.
