Oversized glass, also called jumbo size glass, is increasingly used in modern architectural projects to meet high aesthetic and design requirements. When a building design includes too many glass joints or gaps, the overall visual effect can be negatively impacted. To achieve cleaner lines, wider views, and a more seamless appearance, oversized glass panels are often preferred.
2440mm×3660mm [8’×12″] —————-called oversize（elementary）
3300mm×13000mm [ 10’10“×42’8”] —–for Vivois Oversized Standard
3300mm×18000mm) [10’10“×59’1″)] —-called extreme
2750mm × 6200mm [9′ × 20’4″] ———-for curved tempered glass
In general, glass is considered oversized when the width exceeds 2440 mm (8 ft) and the height exceeds 3660 mm (12 ft).
Oversized glass: width: ≥ 2440mm * (8′) ; height: ≥ 3660mm (12′); extreme lengths: ≥ 18,000mm (59’1″).
Oversized glass can be processed into different architectural glass types, including tempered glass, laminated glass, and insulated glass, depending on project requirements for safety, strength, and thermal performance.
The maximum available dimensions for our standard products are 3,300mm × 13,000mm (10’10” × 42’8″), with custom options available for extreme lengths up to 18,000mm (59’1″). Additionally, we offer curved tempered glass with production capabilities up to 2,750mm × 6,200mm (9′ × 20’4″).
Oversized glass allows architects and designers to create open, transparent spaces while maintaining structural performance and visual elegance, making it an ideal solution for high-end facades, curtain walls, and landmark architectural projects.

Over-size Glass can be manufactured to comply with regional building regulations and performance standards, depending on destination markets.
To demonstrate the practical value of Over-size Glass, here are representative project applications across different architectural sectors. These cases highlight structural capability, manufacturing precision, and export experience.
Location: North America
Application: Commercial Office Tower
Glass Type: Tempered Insulated Over-size Glass
Panel Size: 3300mm × 6000mm
This landmark commercial building required large-format curtain wall panels to reduce vertical joints and create a seamless façade. Our Over-size Glass units were manufactured as double-glazed insulated panels with high-performance Low-E coating to meet strict energy codes.
Key Results:
The use of Over-size Glass allowed the architect to achieve a minimalist exterior while maintaining structural reliability at high elevation.
