overlength

DESIGN AND TRANSPARENCY

From 6 to 18 meters

Producing and installing overlength glass panels with formats from 6 up to 18 x 3.21 meters is now possible. It opens up entirely new creative possibilities for construction actors who dream big.


DESIGN AND USE

Overlength glass shapes the architectural character of a building both from the exterior perspective and in the interior space. Inside, the boundaries increasingly dissolve and daylight floods the space. Outside, the large glass facades appear seamless and monumental.

Overlength glass panes are recommended wherever the goal is to achieve open, airy design with a connection between the interior and exterior environment. The spectrum of applications in construction where Overlength glass panes can be used is broad:

 

Overlengths have their own tradition in architecture: here the UN building in Geneva from 1971 with 13-metre-high windows. 


DESIGN OPTIONS

The usual float glass types (Diamant and Planiclear) and to-be-tempered coatings (COOL-LITE XTREME, COOL-LITE SKN and Planitherm) can be used as Overlength formats. In addition, the glass can be processed, assembled and refined using all the processes known from standard formats.

Saint-Gobain is your partner of choice to assist in building facades with Overlength glazing, offering a strong network of processors and installers to meet your project expectations.

Everything is possible with overlength glass:

  • Pre-cuts and edge processing with an arrissed, a cut or a polished edge
  • Drilled holes in the glass
  • Curved glass
  • Pre-tensioned glass as toughened safety glass, also with heat-soak test
  • Laminated safety glass
  • Fall-proof glazing
  • Design glass with laminated colour or decorative foils
  • Single or multi-coloured patterned ceramic digital printing
  • Full surface enamelling

Uncoated basic glass

SGG PLANICLEAR®

With its low iron oxide content, this basic glass sets new standards when it comes to the look and aesthetics of float glass. Especially for applications involving thicker glass, SGG PLANICLEAR is very convincing thanks to the fact that it lets in more daylight, is more colour neutral and absorbs less light. 

Available in thicknesses of 8, 10, 12 and 15 mm.

SGG DIAMANT®

The basic glass is extremely transparent due to its extremely low iron oxide content and has very little colour of its own. These properties allow the best possible neutrality, even with large and multi-layered glass structures, with natural illumination and undistorted reproduction of colours and contrasts. 

Available in thicknesses of 8, 10, 12 and 15 mm.


Coated glass

SGG PLANITHERM® XN II thermal protection coating

A highly effective and transparent thermal protection coating with a metallic base. The low-emission coating reflects the long-wave infra-red radiation and ensures a very high degree of thermal protection in the insulating glass structure, as well as offering excellent light transmission with a high g-value. SGG PLANITHERM XN II can be toughened to achieve higher mechanical and thermal resistance as is required for projects involving oversized glass panels.

Available in thicknesses of 8, 10 and 12 mm.

SGG COOL-LITE® SKN II sun protection coating

Highly transparent sun protection coating with undistorted colour and a particularly natural lighting effect. The perfectly coordinated combination of superb sun protection, high light transmission and excellent heat insulation ensures an ideal indoor climate in every season. Highly neutral transparency in both directions, meaning it is also suitable for listed buildings. The layers of the SGG COOL-LITE SKN II family can be toughened.

Available in thicknesses of 8, 10 and 12 mm.

SGG COOL-LITE® XTREME II sun protection coating

Highly efficient sunscreen coatings with a selectivity greater than 2 and Ug values up to 0.4 W / (m²K) in triple-glazed panels. Its high selectivity combines excellent light transmission with a low overall energy level transmittance and creates an extremely bright atmosphere inside the room without unpleasant heat. The layers of the SGG COOL-LITE® XTREME II family are toughened, which increases both the mechanical and the thermal resistance.

Available in thicknesses of 8, 10 and 12 mm.

The Broad Museum

Los Angeles

Glass dimensions:  7.50 m x 2.40 m

Architects: Diller Scofidio + Renfro, New York

Half-shade architectural setting

"Invisible" glass in the entrance area of the museum due to seven-and-a-half metre high windows with profileless vertical joints.

The architects at Diller Scofidio + Renfro call their concept for The Broad "veil and vault", which combines two distinct and clearly visible functions in one form: The concave concrete structure inside, like a vault, houses the private collection of contemporary art of the museum's founders, Eli and Edythe Broad, which comprises some 2,000 works of art. The areas above and below this non-public storage facility are used for exhibitions and are fully enclosed by the veil, whose honeycomb-like lattice structure composed of glass-fibre-reinforced white concrete appears like a hovering blanket.

The perforated structure creates a breathtaking effect of semi-shade and filtered light on the upper exhibition level, which is intended to contrast with the normally dazzingly bright streets of Los Angeles. On the ground floor of the exhibition, which appears to have been carved out of the concrete vault of the warehouse, daylight is deliberately utilised to create refreshing half-shade, partly by the veil and partly due to the overhanging building structure.

To enable the twofold nature of this light to be recognisable, the glass of the ground floor had to be colour-neutral, inconspicuous and, in a sense, invisible. This has been achieved with 7.5-metre-high glass panes, which reach from the floor to the ceiling without any cross-section and achieve an extremely visually reduced appearance due to the profileless vertical joints.

The Oculus in the heart of Manhattan

The 800 individual glass panes in total have widely differing sizes, including oversizes of 7.8 x 0.8 meters. 

At the rebuilt World Trade Center subway station in New York, the outline of the underground ellipsis has been continued at ground level by Spanish architect Santiago Calatrava in an impressive construction known as "The Oculus": At a depth of 10 metres below street level is a large, two-storey, oval-shaped piazza. This is covered by a steel-and-glass construction that rises up to approximately 38 metres above ground level.

The ribs of the white steel girders cantilver out on both sides, creating a dynamic figure that might be interpreted in numerous ways. Calatrava himself sees, above all, a bird released into freedom out of the hands of a child. The vertical surfaces between the girders are glazed, allowing daylight to reach the elliptical piazza and, from there, to the platforms. A skylight at the top of the structure also allows a special view of the New York sky and the surrounding skyscrapers.

A total of around 4,000 m² of highly transparent, extra-clear glass with a special sun protection coating ensures that the underground levels are bright with daylight and do not overheat, even under intense sunlight. When the building is lit up at night, the direction of the light and, with it, the perceived ratio of steel to glass are reversed, creating an exciting visual effect: No longer are  the ribs  the dominant element, but rather the pillars of light between them, via which the building illuminates its surroundings.

These columns of light follow the slopes and curvatures of the structure so that a very wide variety of sizes was required for the 800 individual glass panes. Oversized glass elements measuring 7.80 x 0.80 m  among other things have been used for the entrance area. These have the same optical properties as the standard sizes due to the fact that all glass panes stem from the same manufacturer.

Innovation Center

Herzogenrath, Germany 

Glass dimensions: 18.00 × 3.20 m

Architects: Molestina Architekten, Cologne, Germany

Impressive showroom window

A huge glass pane on the ground floor of the new pavilion enables clear views from the outside and inside,  with the foyer façade seemingly having disappeared.

Saint-Gobain is investing in Industry 4.0 and in new technologies and digitization as a result of which the company is expanding and modifying its factory premises in Herzogenrath. In future, visitors to Saint-Gobain will be welcomed in a new pavilion. This new construction embodies the company's openness and love of innovation, which has been realised architecturally using light wood and, of course, lots of glass.

Just beyond the factory gate is the new Co-Innovation Centre, or CIC, with a canteen, meeting and seminar rooms and exhibition spaces. The existing structure of the adjacent research and development centre is also being modernized. Together, the two buildings comprise a new, green central area - known as the "campus". The ensemble is conceived as a place where customers, external partners, universities and colleagues can come together and encourage creative interaction. 

The design by Molestina Architekten from Cologne transforms the three pillars of Saint-Gobain - innovation, sustainability and comfort - into a light-flooded pavilion on an almost square floor plan. The incorporation of glass into an otherwise purely wooden construction demonstrates the full range of Saint-Gobain applications to passers-by while. 

The foyer's west façade is a particular eye-catcher. Visitors are directed past this to the main entrance on the north side. Like a huge showroom window, its vast width of 18 metres allows for exciting views inwards and outwards, causing the interior and exterior spaces to visually merge. On this scale and in this form, this represents something truly unique. 

The two-storey foyer behind it serves as both a reception and exhibition area, onto which the canteen will also be joined. An open staircase with a back wall made of wooden slats leads to a gallery on the top floor, from where there is a choice of going directly into meeting rooms or, alternatively, to a pergola on the north façade, then continuing to a bridge made of reinforced concrete and glass connecting the new building to the old.

The structure of new Co-Innovation Centre radiates clarity and openness, an effect produced both by the design and the materials. The massive glulam panes combined with the glass panes create an exciting spatial structure. In addition, the reduced range of natural materials creates a warm, lively atmosphere.

Exhibition Center

Salzburg, Austria

Glass dimensions:  2.20 × 6.50 m

Architects: kadawittfeldarchitektur, Aachen, Berlin

Trade Fair with panoramic views

The large-size glass panes used in the façade enable visitors and conference guests at the Messezentrum Salzburg to enjoy a panoramic view of the exhibition area and beyond, all the way to the Alps.

In recent years, the architecture of trade fair halls and convention centres has undergone dramatic changes. Whereas in the past they were planned as functionally inward-looking areas on greenspace, recently the focus has increasingly shifted to both integration into existing structures and relationship with the environment. This is the case with the Messezentrum Salzburg too. Despite the need to accommodate large numbers of visitors, the new, cube-shaped building by kadawittfeldarchitektur from Aachen has been integrated elegantly into the existing, ring-shaped hall structure while also complementing the exhibition area with a striking extension. The nearly 28,000 square metres of floor space encompassing the foyer, multifunctional hall, seminar rooms and adjoining areas have been compactly arranged on two levels by the architects. On the ground floor, the recessed foyer welcomes visitors, while on the upper floor, the projecting conference area offers an unrestricted view of the trade fair landscape and, in particular, a breathtaking panoramic view of the mountains down the trade fair boulevard through the huge, storey-high window front. 

The design of the glass façade facilitates subtle but exciting interaction between interior and exterior. The impressive views are made possible by the large-size glass panes measuring 2,200 x 6,500 mm containing extremely colour-neutral CLIMATOP COOL-LITE SKN 165 solar control glass. The surface of the glass measures approximately 650 m2 and can also be backlit in different colours, depending on the desired mood.

Exhibition Center for Building Materials

Etoy, Switzerland

Glass dimensions: 2.80 × 5.50 m

Architects: Alain Porta, Lausanne + Wurlod Architects, Pully

Large sizes for clear lines

In Etoy on Lake Geneva, the products of a building materials retailer  have been displayed in a special ambience bathed in natural light. 

At first glance, the strictly formal cubature covering a floor space of 93 x 43 m and the windowless longitudinal fronts appear somewhat closed off and almost introverted. But the glass façades on the north and south sides, as well as the courtyard, which is also completely transparent, create a bright interior offering constantly changing views of the outside. Conversely, in darkness, the exhibition centre appears to viewers on the outside as a weightless, seemingly floating light sculpture.

Following the geometrically minimalist structure of the entire building, deliberately large glass panes with dimensions of up to 2,781 × 5,474 mm have been used, which allow a greater light incidence thanks to fewer profiles and, at the same time, emphasise the clear lines of the architecture. In total, there are 2,200 m² of glass with different sun and heat protection qualities, weighing up to 1,200 kg per element.

These large sizes and heavy loads on the main façades tilting outwards by 23° posed a particular challenge and technically speaking constitute overhead glass.  As well as being an architectural idea, the tilting is part of the sophisticated climate concept: direct sunlight is avoided on the south side because the building casts its own shadow, thus reducing both heat loads and the need for sun protection coating.

The courtyard façades are shaded by horizontal slats in the upper sections of the windows. At the same time, there is a special adiabatic cooling system: During the hot season, jets on the doors and under the trees spray a cooling veil of water vapour. The conditioned air can be routed through the building and discharged via motorized roof openings.
