Throughout this series, we will delve into the cutting-edge advancements and innovations in insulating glass (IG) production. This first episode is dedicated to the �ձʳ�® technology. Join us as we uncover the history of �ձʳ�®, what sets this technology apart and what new developments are available today for IG producers.

�ձʳ�® stands for Thermo Plastic Spacer, belonging to the “warm edge” spacer category. However, �ձʳ�® represents much more than a mere acronym. It encompasses precise and robust technology for producing double to quadruple IG units.

History of TPS

The origins of �ձʳ�® trace back to 1994 when the company’s visionary founder, Karl Lenhardt, recognized the pressing need to automate insulating glass production. Soon after, an applicator was developed that applied the spacer directly onto the glass – first horizontally and then vertically, as is done to this day. This process revolutionized insulating glass production by eliminating manual spacer application.

Presently, more than 160 �ձʳ�® IG production lines are operational worldwide. This translated into over 100 million �ձʳ�® IG units produced on these lines to date.

Advantages of the TPS technology

The �ձʳ�® technology offers numerous advantages. Most notably, all IG units can be produced on a single production line – regardless of their format. This eliminates the need for separate production steps such as sawing, bending, connecting, desiccant filling and butyl-coating. And thanks to the high level of automation, the process requires only two operators.

To support sustainability, �ձʳ�® ensures the right spacer in exactly the right quantity, with no waste or offcuts.

Last but not least, �ձʳ�® makes uninterrupted operation possible due to the special dual-drum pump system, which allows drum changes without stopping the operation. Furthermore, the newly developed and Glaston-patented follower plate optimizes the material flow, resulting in up to 35% improved material output.  

All these benefits significantly save time and money for IG producers.
