Before the Doors Open: A Sneak Peek at glasstec’s 2026 glass technology live
A day before glasstec 2026 opens its doors, Messe Düsseldorf gave press an early look at glass technology live, the show’s special exhibition of research and industry innovation. Professor Dr. Ulrich Knaack, one of the leading experts behind gtl, led the Oct. 19 preview tour as exhibitors and crews finished their preparations for the show opening.
glasstec runs Oct. 20-23, in Düsseldorf, Germany, and is built around three themes: the circular economy, digital technologies and decarbonization. The gtl exhibits, contributed by companies, research institutes and universities from Germany and abroad, put those themes into physical form.
The displays at glass technology live in 2026 demonstrate the range of performance challenges put before the industry, with demands for products that meet increasingly rigorous functional, aesthetic and sustainable requirements.
“In the 90s, the innovations were pure structure,” says Knaack. “In the 2000s, we saw double glazed systems. Now, it’s a lot more diverse. We are seeing products for energy, longevity, circularity; tooling to help with digitalization. We’re seeing the complexity of the industry.”
Seen at the glass technology live preview
The theme of reuse and recycling is apparent in several of the gtl exhibits. Eckersley O’Callaghan’s Full Circle pavilion is made of 54 identical curved laminated glass elements that slot together by hand, with no frames or screws, so the structure can be easily reconfigured or rebuilt.
A foldable glass wall from TU Darmstadt’s Glass Competence Center and Frankfurt University of Applied Sciences reprocesses glass recovered from insulating units and laminated safety glass, joining the panels with laminated zip fasteners.
Large-scale and complex forms also drew attention. Luoyang North Glass’s MONOLITH installation uses eleven cast-glass panels nearly 15 feet tall to support a glass roof holding a pool.
Additionally, Sedak is showing a jumbo-size multi-axis bent tempered glass lite, produced through a multi-curved process that produces sizes up to about 40 feet long and 12 feet wide without molds.
Energy generation continues to be a focus of innovation in glass. The tour included an exploration in new building integrated photovoltaic modules, with Sunovation. The custom BIPV glass modules offer new opportunities in colors and shapes for energy-generating glass façade materials.
The artistic glass centerpiece of glass technology live is Réflexions, a lattice of about 1,400 glass prisms, roughly 10% of them made from industrial offcuts. The piece was created by Atelier Emmanuel Barrois.
