Spectrally Selective Tinted

Understanding Spectrally Selective Glass

Spectrally selective glass is defined as glass with a Light to Solar Gain ratio (LSG) of 1.25 or better. LSG is equal to the Visible Light Transmittance (VLT).divided by Solar Heat Gain Coefficient (SHGC).

Spectrally selective glass takes advantage of natural daylight while lowering solar heat loads. As a result, architects and designers can minimise reliance on artificial cooling and lighting in a commercial building, resulting in reduced building operating costs.

PPG Glass Technology provides a range of products, including Solarban 60 and the Oceans Of Colour range of tinted products, that meet or exceed this requirement. In some cases lead their categories in energy efficiency with LSG ratings as high as 1.86.

The ‘Oceans of Colour’ palette is reserved for the highest performing spectrally selective (see below) tinted glass products. They provide buildings with a desirable low solar heat gain coefficient and high visible light transmittance — in a versatile range of creative colours.

A strikingly beautiful aqua-green colour, Caribia™ Glass will blend naturally with surrounding building materials to create remarkably attractive commercial structures. Caribia Glass boasts qualities similar to the best performing spectrally selective glass products with visible light transmission of 67% and solar heat gain coefficient of 0.50.

When incorporated in a 24mm I.G. unit the performance is even more impressive with visible light transmission of 60% and solar heat gain coefficient of 0.39.

(formerly Azurlite^®)

Azuria™ Glass is an ideal blend of solar control and visible light transmittance in a stunning aqua-blue appearance. The solar heat gain coefficient of Azuria Glass in a 24mm I.G. unit is an extraordinarily low, 0.39. Yet, visible light transmittance is a high 61%.

Even when used monolithically Azuria Glass provides an excellent solar heat gain coefficient of 0.50 with visible light transmittance a fantastic 67%.

(formerly Solargreen^®)
Atlantica™ Glass is an emerald-green glass that combines desirable high visible light transmittance (67%) with low solar heat gain coefficient (0.51). When used as the outer light of a 24mm I.G. unit, Atlantica glass provides 60% visible light transmittance and a solar heat gain coefficient of 0.40.

Its sparkling green colour is especially striking against light coloured facades.

(formerly Solex^®)
Solexia™ Glass is a light green tinted glass that has provided aesthetic and performance solutions for builders and architects world-wide for decades. Its light green colour subdues interior brightness while still providing the highest visible light transmittance (77%) of any tinted glass available. This is combined with a solar heat gain coefficient of 0.60.

Earth Tone Series

In addition to the “Oceans of Colour,” PPG offers a powerful aesthetic statement with an expansive earth tone palette featuring our Performance Gray and Tinted Glass products.

PPG PERFORMANCE GRAY

Optigray^® 23 Glass
Optigray^® 23 Glass is a medium gray-tinted glass with a warm undertone and improved solar control properties. It maintains a light transmittance of 21% in a 24mm I.G. unit and blocks 67% of the total solar energy. The solar heat gain coefficient in a one-inch I.G. unit is one of the lowest of any architectural tinted glass product: 0.29.

Graylite^® Glass
A rich, dark gray, Graylite Glass combines heat load reduction and solar control with a distinctive colour contrast. Its solar heat gain coefficient is 0.34 for a 24mm I.G. unit while visible light transmittance is 12%, making it ideal for glare control and privacy glazing.

TINTED GLASS

Solargray^® Glass
Solargray Glass combines a cool light-gray appearance with the ability to control solar heat gain and glare.

Solarbronze^® Glass
Solarbronze Glass, in a warm bronze appearance, reduces solar heat gain and glare while providing a visible light transmittance of 47% in a one-inch insulating unit.
