The Glass

We must invent and learn at the same time

Viraver designs, develops and manufactures flat or curved glass sheets, laminated security glass and other bespoke glass products tailored to the Nautical, Automotive, Architecture, Industrial and Armoured sectors.

For each sector and circumstance, Viraver contextualizes its products with particular attention to norms, regulations, and individual specifications. The company’s innovative solutions come as the design trend is heading towards ever larger glass applications. Viraver’s unique specialty is to deliver these large sizes using thinner sheets of glass, for a consequent weight reduction, but with no loss of resistance or structural quality.

Process

viraver vetro curvatura n 002

Viraver uses the sag bending technique to create large curved surfaces.

With this technology, even very thick sheets of glass can be bent, to form cylindrical and spherical curves, while retaining excellent optical properties and creating surfaces free of flaws, distortions and undulations.

The experience acquired in obtaining curvature, and using the 3D processing technique for surface detection, allows the team to guarantee the continuity of the surfaces even in the most complex projects. Viraver’s larger new furnaces are able to bend glass sheets as large as 21.32ftx10.17ft (6,50mx3,10m).

The chemical strengthening process of glass is used to improve the physical characteristics of glass, increasing its resistance to mechanical stresses and to thermal shocks.

The chemical strengthening process by its nature does not involve any kind of optical distortion and imprint on the treated glass.

The chemically strengthened glass is not subject to the risk of spontaneous rupture from inclusions of Nickel Sulphide and therefore does not require Heat Soak tests.

Viraver prides itself on being the only company to be able to produce chemically strengthened glass sheets as large as 26.4ftx10.53ft (8mx3,21m).

Silkscreen printing is a glass printing technique which serves both aesthetic and and functional purposes, as it helps to safeguard the quality of the gluing.

It is achieved by printingon glass or plastic interlayer, with the use of silkscreen printing frames and suitable ink of compact and shaded bands.

Laminated glass is one of the most used products in projects where glass is a structural part because it combines transparency with the robustness and security features required by standards and norms.
In Viraver lamination is executed for each piece of glass by bag technique and autoclave cycle.
The stratification techniques used in Viraver allows innumerable materials to be added to the plastic interlayer that further enhance the purpose to the glass, for example: heating elements, heat shields, electromagnetic radiation shields, electric and decorative opacifier films.

This is the process in which the union between the glass and the plastic material that make up the stratified takes place. In Viraver lamination is carried out in an autoclave, which consists in subjecting the laminate to the simultaneous action of pressure, temperature and vacuum in order to generate the intimate union of the different materials. Viraver is equipped with a new large autoclave for glass and polycarbonate sheets equal to 29.53ftx10.83ft (9mx3,30m).

Viraver interprets the implementation of glass and considers it as a design element functional to its purpose and this product, one of the protagonists, has the characteristic to blend chromatically with the colors of the hull creating an almost total uniformity, until one gets closer to the yacht and the integral element (glass) can be discerned.

The privacy offered to the interior spaces is guaranteed by the way the dots are configured which cut the source of direct or indirect light therefore incrementing the shielding ability from the exterior towards the interior and is so doing offering a private and comfort area.

Viraver confirms its commitment to research and development to find new usages and technologies and its ability to create bespoke products thanks to its team of specialists who work closely with the client.

Nowadays, during the stages of development of Super and Giga Yachts, the fire resistance characteristic is more and more frequently requested; this property is determined through the application of the Fire Test Procedure Code issued by the IMO.

Viraver has introduced to this specific safety sector a fire protection system of excellence, which confirms Viraver Technology’s leadership in the yachting sector.

Viraflame revolutionizes the concept of fire rated windows using an exclusive technology.

A system certified by Viraver, which seamlessly combines the need for safety and design, offering superior quality, compared to traditional products on the market, in terms of reduced thickness, transparency and stability of quality in time.  The fire protection system Viraflame, in fact, does not use intumescent gel but rather exploits design innovation related to the frame, the type of fixing and the sequence of installed materials.

The classification obtained, in accordance with the FTP tests, is A0 (extendable to A30 with dedicated splinklers), with a maximum size for the element equal to 3m X 2m.  The Viraflame system also complies with the Passenger Yacht Code – CISR.

The weak point of the classic fire-resistant glass with intumescent is in its instability. Already at temperatures ranging from 70° to 80°, that can easily be reached simply by direct exposure to sun rays, the gel begins to react to the temperature, causing bubbles and progressively losing its transparency.

The fire protection system Viraflame, maintains its qualities of transparency unaltered even over the passing of time.  Because the system does not use intumescent gel, both in normal circumstance and during a fire on board, the transparency of the glass guarantees that  one can see and evaluate the eventual state of danger.
