PPG Solarban Solar Control Low-E Glass - image 1

Solarban^® Solar Control Low-E Glasses
Solarban^® 60 was engineered to control solar heat gain, which is essential to minimizing cooling costs. In a standard one inch insulating glass unit, Solarban^® 60 has the following features:

Exterior appearance similar to clear, uncoated glass
Blocks approximately 60% of the total solar energy
Excellent insulation value (U-Value = 0.29)

Solarban^® 60 glass is now available on Starphire^® ultra-clear glass and can also be combined in insulating units with an outboard lite of a PPG tinted or reflective tinted glass to increase performance options (see performance data to right and on page 21).

Note: This product meets the new energy efficiency guidelines set forth by the Federal Energy Management Program (FEMP) for spectrally selective glazing products.

LSG Ratio: Using the Light to Solar Gain Ratio (LSG) allows performance comparisons to be made between glazing products, and highlights the standards set by PPG glasses. The LSG ratio is the ratio of visible light transmittance to solar heat gain coefficient. The higher the LSG ratio, the better the glazing is at reducing unwanted solar heat gain and maximizing desirable natural light transmittance. Excellent LSG ratios can be attained using spectrally selective tinted glasses and/or Solarban^® Solar Control Low-E glasses.

Solarban^® 80 glass is designed to address the need of a single product for superior solar control, high visible light transmittance and aesthetic appeal.

Like no other glass, Solarban^® 80 glass creates a dynamic exterior aesthetic. A sample viewed indoors provides a glimpse of the same steel jade appearance exhibited by Solarban^® 80 glass when shaded from the sun. When the glass is bathed in direct sunlight, the glass transforms into a satin reflective finish, with true color reflected images...of the sky that looks blue and trees and landscaping that look green.

Solarban^® 80 glass has a Light to Solar Gain (LSG) Ratio* of an unbeatable 1.96, placing it at the top of its class.

A one-inch insulating unit of Solarban^® 80 (2) clear glass provides:
Optimum balance among visible light transmittance, glare control and superior solar control
A satin finish that reflects undistorted images, clear and crisp, but not overpowering
Solar control properties that meet the most stringent mechanical requirements
True color transmittance for building occupants
