The fire resistance feature is increasingly demanded in many sectors and especially in the yacht sector; this property is determined by applying the Fire Test Procedure Code issued by the IMO. Viraflame revolutionizes the concept of fire resistant windows, combining perfectly safety and design requirements, offering superior quality to traditional products on the market, even in terms of thickness reduction and transparency.
The Viraflame firefighter system does not include intumescent gel but 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 (extensible A30 with dedicated sprinklers) and with maximum dimensions of the parental element of 7.35ftx9.67 (2240mmx2950) (free light 7.23ftx9.5ft (2214mmx2914mm).
This system also complies with the requirements of the Passenger Yacht Code – CISR.
CHEMICALLY STRENGTHENED GLASS / CHEMICAL STRENGTHING PROCESS
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 practical purposes.
At Viraver, we use two printing technologies:
CLASSICAL SILKSCREEN PRINTING • Which involves printing by means of silkscreen frames and inks on compact and shaded, black and colored strips, which protect the glues used to install the glass, while at the same time creating an attractive aesthetic effect in the combinations of glass and structure.
PRINTING ON PVC • Viraver is a Kuraray licensee for SentryGlass® Expression™, a type of technology which enables high definition coloured images to be printed continuously on both transparent and opaque interlayers.
CLEAN ROOM ASSEMBLY
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 lamination 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 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 optical, foreign and sizes of products. The controls on the finished product are made by qualified national experts.
