Stepped IGUs are used primarily in modern structural and unitized façades, where the seamless, glass-only exterior must be paired with high technical performance. The step enables a durable and watertight connection between the glass and the aluminium structure using appropriate structural silicones, while also facilitating proper drainage and stress compensation.
Stepped units are manufactured exclusively from tempered or heat-treated glass, and their production requires precise adaptation to the specific façade system.
Corner glass is also available in stepped variants, allowing architects to create striking glass corners without the need for visible aluminium profiles.
Glass corners are an increasingly popular architectural feature in both residential and commercial buildings. At Vitroterm-Murów, we produce corner IGUs bonded at a right angle, without mullions or aluminium profiles.
This solution creates the effect of a continuous glass surface, opening the interior to the surroundings and providing maximum daylight and panoramic views.
Stepped insulating glass units are used not only in facades but also as safety floor glass in balconies, mezzanines, walkways, and landings. The stepping—the recessing of one pane relative to the other—allows for the aesthetic concealment of the glass edges and precise embedding of the unit in the supporting structure, without visible frames or mounting elements.
This solution is widely used in modern architecture, both indoors and outdoors—wherever glass serves not only as a structural element but also as a decorative one.
The production of stepped glass requires the use of modern processing and cutting technologies that ensure perfect panel geometry and maintain strength parameters. Each step—from tempering, through layer bonding, to the application of functional coatings—is subject to strict quality control, as even the slightest deviations can impact the safety and aesthetics of the entire façade.
In practice, this means that stepped or corner glass panes are created based on custom designs, tailored to the architect's requirements and the façade system in which they will be installed. This allows designers and investors considerable freedom in designing façades while maintaining the highest technical and safety standards.
