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)

Doors without SuperSpacer use Bayform’s Thermal Edge. It is a steel spacer that is significantly warmer than an aluminum spacer

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.
