Large-format insulating glass units are technologically advanced glass assemblies reaching sizes of up to approx. 3200 × 6000 mm, with a weight of up to 1.5 tonnes and a thickness of up to 100 mm. These parameters make it possible to execute exceptionally demanding architectural concepts.
Their multi-layer construction provides stability and excellent performance despite their impressive dimensions. Each unit consists of at least two panes separated by spacer frames, filled with noble gas (e.g. argon), ensuring superior thermal insulation.
Large-format insulating glass units with a step edge are an innovative solution designed for architecture where glass plays both an aesthetic and structural role. The step element perfectly complements contemporary large-format glazing, accentuating its minimalist character.
This characteristic offset allows for the concealment of structural components such as spacer bars or aluminium profiles. As a result, only a smooth, uniform glass surface is visible from the outside, giving the façade a sleek, modern appearance.
Such glass types are primarily used in structural and element façades, where aesthetic excellence must be accompanied by precise workmanship and long-term durability. The step design enables stable and watertight integration of the glass with the aluminium structure while ensuring proper drainage and stress compensation caused by temperature fluctuations.
At Vitroterm-Murów, large-format step-edge IGUs are produced exclusively from tempered or heat-treated glass, guaranteeing safety and durability in demanding façade projects. Every unit is engineered to match the specific façade system, ensuring perfect compatibility and a flawless final appearance.
Multi-layer construction – combining several glass panes into a safe, durable, airtight unit resistant to loads and temperature variations.
Exceptional thermal insulation – low-emissivity coatings reduce heat loss in winter and help prevent overheating in summer, meeting the requirements of energy-efficient and passive buildings.
Safety and impact resistance – tempered or laminated glass with PVB interlayers protects against injury in case of breakage and may provide anti-burglary performance.
Solar control – selective coatings block thermal radiation while allowing natural daylight to pass through.
Acoustic comfort – high-performance acoustic units effectively reduce noise, which is especially important in urban environments.
Together, these technologies ensure that large-format glazing delivers reliable, high-quality solutions for premium architecture
