Glass coating technology for that functional and attractive finish

Coating Technology

Architectural glass showcases buildings. Grenzebach’s PVD coating technology turns the raw material into an energy-efficient component. PVD large-area glass coating is a core technology that meets requirements in terms of functionality and appearance. Grenzebach provides turnkey equipment for the entire coating process and materials handling. We’re the only supplier when it comes to fully automatic and customized coater solutions that can produce thermal insulation and solar control layers on glass. And of course, service for the PVD coaters installed worldwide is part of the package. Three decades of experience mean we know coaters inside and out.

Quality of life of the glass with the right coating

The feel-good factor.

Coating technology. Or

Glass plays a pivotal role in delivering a healthy indoor climate in homes and workplaces. It fulfills people’s needs for interiors that are light, cozily warm or pleasantly cool. All of us encounter glass hundreds of times every day and it helps foster that feel-good factor. Glass controls how bright rooms are, but does much more than that, it creates an atmosphere. This aspect should be very important to us, because, after all, we spend about 80 percent of our time indoors nowadays.

These are all aspects that stem from the unbeatable performance of coatings applied in the coater. Due to their composition, the coatings are so temperature stable that the sheets of glass can be bent or turned into safety glass at high temperatures.

From Solar Control to high-end Low-E coating systems

Our fully automatic PVD coaters allow the production of state-of-the-art coating systems ranging from Solar Control to high-end Low-E coating systems. The coaters can also apply all types of coating destined for exclusive products. Examples include

  • dielectric (electrically insulating) materials such as Si3N4 or TiO2
  • to ultra-thin metal and blocker layers like Ag and NiCr
  • all the way to special coatings for use in displays or the solar industry such as transparent, conductive layers (ITO, ZnO, ZnMgO).

Our PVD systems are designed to deliver anything customers could possibly want in terms of coating.

Coating lab

Our new coating lab’s main purpose is to create products for tomorrow’s world. The lab was custom built to carry out experiments and tests in order to develop and adapt glass coating technology.

The jumbo glass coater is deal for research and development and all lab application requirements. It’s one of the world’s few lab coaters that can operate on substrates that are up to 3.4 meters or approx. 11.15 foot long. The coaters can also apply all types of coating destined for exclusive products.

Integrated control

An integrated control concept takes coating-line productivity and efficiency to a new level – a benchmark for all the coating and handling machinery. Interlinking production steps, as well as tracking and analyzing machine parameters, are what make needs-based maintenance and therefore longer service lives possible in the first place. We’ll liaise with you to shift to flexible maintenance and cleaning based on actual requirements. Downtime and coating costs drop while productivity rises. We generate added value for customers paired with maximum flexibility.
