Glas Trösch has introduced Silverstar Light, a thin triple insulating glass unit featuring an ultra-thin 0.5 mm center pane from Corning made of Enlighten Glass, positioning the innovation as a lightweight alternative for modern glazing applications. As the first processor in continental Europe to adopt this technology at scale, Glas Trösch is targeting improved installation efficiency and reduced structural load across new build and renovation projects.

Depending on configuration, the system reduces total insulating glass weight by 17% to 47% compared to conventional 4 mm pane assemblies. This reduction simplifies handling on site and can support slimmer frame and fitting designs, while also improving long-term durability of window systems.

Two variants are available: the 0.5 mm ultra-thin center pane and a 2 mm option suitable for laminated safety glass (VSG), meeting required safety standards. Performance remains comparable to standard triple glazing, with Ug values as low as 0.5 W/m²K, alongside strong acoustic and light transmission properties. Solar control coatings can be integrated to manage summer heat gains.

Sustainability is a key advantage, with a calculated CO₂ footprint of 2.88 CO₂ eqv/m², over 20% lower than conventional insulating glass units under EN 15804+A2 methodology. Certified under DIN EN 1279-2 and 1279-3, Silverstar Light is available in sizes up to 1500 × 2200 mm.

Field tests confirm durability and ease of installation, supporting use in energy-efficient façade systems and renovation upgrades across residential and commercial buildings. Manufacturers highlight compatibility with existing frame systems and improved lifecycle performance under demanding climatic conditions across Europe markets today.
