There are lots of Glazing options to choose from. Choose the order you would like the Energy Ratings to be sorted by (Whichever order is most important to you):
- Use for passive solar applications or where
heating load reduction is the priority
- Use where thermal comfort is the priority
- Use where cooling load reduction is the priority
See the
American Recomendations (Energy Star) for thermal performance and compare them to the values below!

The Fine Print:
* Glass Code:
- 1st digit - number of layers of glazing
- 2nd digit - number of SuperSpacers
- 3rd digit - number of Low-e coatings and argon gas fills (assumed 90%argon, 10%air)
The number after the Low e manufacturer’s name shows the location of the Low e coatings - surface #1 is the exterior surface
Window Properties were determined by FRAMEplus5.1, which incorporates VISION
U-values that conform to ISO 15099 (used in Europe), are typically 10% lower than those stated above and are available on request
Other types of Low e glass are available on a custom or project basis
