Viridian VTough™

Creating physical but not visual boundaries

Whenever the benefits of ordinary glass need to be combined with extra strength, safety or heat resistance, Viridian VTough™ toughened glass offers a complete and proven solution, allowing designers and specifiers greater scope with glass for building.

Product description

VTough toughened glass is a Grade A safety glass manufactured to AS/NZS 2208 for use in buildings or AS/NZS 2080 safety glass for land vehicles. It is manufactured by heating and then rapidly cooling flat glass. As a result, balancing compressive and tensile stresses are set up in the glass, which gives toughened glass four to five times more strength than ordinary glass of the same thickness, combined with much greater resistance to impact. In the unlikely event of breakage, the glass forms small granules. VTough toughened glass cannot be cut or edgework processed after manufacture.

Range

Virtually all glass types can be supplied in toughened form, the exceptions being some deeply DecorPatterned glass and glass for leadlighting.

Considerations

• Heat Soak treatment is recommended in certain applications by Viridian to provide a superior quality glass and may be a Viridian warranty requirement
• Tolerances – as listed in customer acceptance standards and AS/NZS 2208, toughened glass is inherently less flat than ordinary glass
• Wind load – toughened glass can be used in larger areas than ordinary glass of the same thickness. This allows a consistent thickness and appearance to be achieved in areas of higher wind load or panel dimensions. Deflection should be checked
• Selection and glazing – glass must be selected and installed in accordance with AS1288 or NZS 4223. Attention is also drawn to the breakage characteristic of toughened glass and it is the specifier’s responsibility to assess each application

Features

• Strength – Toughened glass allows large, clear spans with minimum fixing. Toughened glass is used with bolt or patch fittings for frameless doors and assemblies, or glass shapes including holes that may weaken normal annealed glass. Toughened glass has good resistance to soft object impacts. For example, it is often used for basketball backboards
• Thermal resistance – resists temperature differences of 250ºC in a range of – 70ºC to +300ºC. This means that toughened glass can be used in appliances, splashbacks and where thermal stress breakage is an issue
• Heat strengthened glass – this is not a safety glass, but has approximately double the strength of ordinary glass. It is resistant to thermal breakage (temperature differential of 180ºC) and if broken, breaks into large pieces. The glass is used in building spandrel areas because it is flatter than fully toughened glass or also used where additional strength without safety is required such as the corners of buildings for high wind load
• Viridian Seraphic™ is toughened glass with a screen printed ceramic solid colour or design
• Laminated – can be laminated for additional safety, solar control or appearance
