Viridian EnviroShield Reflective™

Sheer brilliance in solar reflectivity

Description

Viridian EnviroShield Reflective™ high performance reflective glass is a solar reflective glass that utilises a permanent metallic coating applied through the vacuum sputtering process. EnviroShield Reflective significantly reduces solar heat load on a building facade, both reducing air conditioning loads and providing a reduction in capital and operating costs. The coatings are spectrally selective and work efficiently by reflecting and absorbing over 70% of infra red solar radiation. EnviroShield Reflective has enabled designers to use large glass areas economically and is typically specified on buildings that have extensive glass or curtain-walls, or where a reflective appearance is required for consistency and privacy.

EnviroShield Reflective is available in a monolithic and laminated range of coatings. These have been developed for Australasian conditions, where a balance of light transmission and external reflectivity has been achieved in an environment demanding very high solar and glare control. The EnviroShield Reflective range has been developed in conjunction with local council requirements for reflectivity.

EnviroShield Reflective can be incorporated into insulating glass units for enhanced solar and thermal insulation. It must be toughened or heat strengthened before coating or laminating.

Coating characteristics

• Coatings are designated by type (two letters) and by light transmission (two numbers) on 6mm clear glass. The lower the light transmission numbers, generally the higher the solar control and reflectivity
• There are three standard coatings: Sky Blue (TS), Silver Grey (SS), Silver (SL)
• The SL coating is laminated only

Considerations

• The coating must not be glazed to the exterior of the building
• A thermal safety assessment is essential prior to ordering
• Refer to handling, glazing and site protection guidelines on our website
• The glazing system requires particular attention to avoid distorting the glass
• Toughened and heat strengthened glass has a degree of distortion and is not as flat as standard annealed or laminated glass
• Viridian VTough™ must be Heat Soak treated

Spandrels

EnviroShield Reflective for spandrels will need to be heat strengthened. It can be supplied with an opacifier to prevent see through. In these locations, use glass with light transmission of 20% or less. Another method is to use Viridian ThermoTech™ made with an outside panel of EnviroShield Reflective and the inside glass to the unit an opaque Viridian Seraphic™ glass.

Coated surfaces

The coated surface identifies how the glass should be glazed. EnviroShield Reflective Monolithic has two surfaces, #1 is outside, #2 is inside. A laminate has four glass surfaces, #1 is outside, #4 inside. The coating must never be glazed outside.

• The coatings are applied to 6mm clear, grey or green glass as standard products. On inquiry these can also be applied to Viridian SuperGreen™ and Viridian SuperBlue™ or 10mm clear substrate glass
• Other non standard coatings – TS40, TS50, SS08, SS14, TE10 – Gold, SC (pewter) – SC20, SC30, SC40
• For laminated glass only, other non-standard coatings are SL10 for solar control, SL30 for higher light transmission
• Tempered laminates use a thicker 1.52mm PVB interlayer

Features and benefits

EnviroShield Reflective Laminated

The coated glass is laminated with a PVB interlayer to clear float glass. By using tinted interlayers a wide range of colours and thickness are available. These configurations using clear glass mean that EnviroShield Reflective™ Laminated glass is less susceptible to thermal breakage than coatings on tinted glass.
