The PPG architectural glass products described in this program can be combined into a myriad of window systems to satisfy both the aesthetic and performance requirements of your projects. The examples shown here illustrate how significantly the energy performance of a building can be influenced by the glass combination chosen.
The first four diagrams illustrate how dramatically the performance of a one inch standard insulating unit can be enhanced by substituting a spectrally selective glass, and how even more dramatic improvements can be attained through the addition of various PPG Low-E coatings.
The other four diagrams illustrate how visible light transmittance can be adjusted to your specific needs by selecting the right PPG tinted glass in combination with our outstanding Solarban® 60 Low-E glass.
All of the examples show important solar energy values under summer daytime conditions, the time when maintaining the total solar energy transmission at a manageable level is a must for your HVAC cooling system. The standard ASHRAE summertime conditions that apply to all of the examples shown are:
Incident Solar Radiation = 248 Btu's/hr/ft²
Outdoor Air Temperature = 89°F
Indoor Air Temperature = 75°F
Outdoor Air Velocity = 7.5mph
Indoor Air Velocity = 0 mph
Also illustrated at the bottom of each example is the winter nighttime U-Value
for the I.G. Unit shown. The standard ASHRAE Winter nighttime conditions for
determining U-Value are:
Outdoor Air Temperature = 0°F
Indoor Air Temperature = 70°F
Outdoor Air Velocity = 15 mph
Indoor Air Velocity = 0 mph
And, these are only a few examples of the many combinations available.
With the broadest glass product line in the industry, PPG stands ready to provide the aesthetics you desire with the performance your project demands.
