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.
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 is 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 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 large new autoclave for glass and polycarbonate sheets equal to 29.53ftx10.83ft (9mx3,30m) in addition to the pre-existing one.
Viraver has an ISO 9001: 2015 certified quality management system. Viraver monitors all business processes in order to improve the effectiveness, efficiency and quality of its processes, products and services. Viraver systematically controls its products before delivery with the aim to verify the customer’s standards, and in particular in particular the optics, aesthetics and dimensions of the products. The checks on the finished products are carried out by qualified national experts.
