Glass Packages (R-9 with SuperGlass)

The Clear Choice for Insulated Glass

All ProVia Aeris, Endure, and Aspect windows come with the ComforTech™ Warm Edge Glazing System, featuring the Super Spacer® Reverse Dual Seal Technology, for reduced heat loss, warmer glass temperatures and reduced interior condensation.  All our ComforTech products have passed stringent testing and are IG Certified to insure our seals are durable and will not leak.

Our DLA-UV, and TLK options further improve energy efficiency, with high-performance Low E coating, UV protection and insulating chambers filled with Krypton or Argon gas, certifying ProVia windows for ENERGY STAR® rating.  To see which window styles and glass options meet ENERGY STAR criteria in your climate zone, use our Thermal Performance Calculator.


Options For Aeris™, and Endure™ Series Windows

  • Ultimate energy savings in a triple glazed unit
  • High Performance Low-E coating applied to two panes of glass
  • Both insulating chambers are filled with Krypton gas
  • 1″ IGU thickness

  • High Performance Low-E coating with increased UV protection applied to one surface of glass
  • Space is flooded with Argon gas
  • 1″ IGU thickness
  • Enhanced double glazed package
  • High Performance Low-E coating applied to one pane of glass
  • Hardcoat Low-E applied to one pane of glass offering better solar heat gain performance
  • Space is flooded with Argon gas
  • 1″ IGU thickness

What are the advantages of increased UV protection?

Cooler in Summer:
Solar Heat Gain Coefficient for DLA-UV is 65% better than clear glass and 30% better than DLA.

Increased Fade Protection:
Damage Weighted Transmittance for DLA-UV is 43% better than clear glass and 23% better than DLA.

Damage Weighted Transmittance, is calculated according to a function called Tdw-ISO, developed by the International Standards Organization (ISO) and published by the International Commission on Illumination (CIE), the world’s leading technical organization on lighting and illumination. The Tdw-ISO calculation measures fading risk from solar radiation across the entire solar light spectrum, from Ultra-Violet light (280-380 nanometers) through visible light (390-780 nanometers). According to the CIE standard, which is considered more comprehensive than Ultra-Violet rating alone, our UV glass packages can minimize fading damage across the entire solar spectrum more effectively than glass designed primarily to block Ultra-Violet light.

– All calculations based on 7/8″ thick, double glazed, single strength IG units using NFRC methodology with Lawrence Berkeley National Laboratory’s Windows 5.2 software.

ComforTech™ Advantages

The NO-Metal Advantage

“Thermal efficiency through no presence of conductive metals” is the Super Spacer® hallmark.

Mylar 10-Layer Vapor Barrier

The Super Spacer® thermoset foam matrix is exceptional. Moisture is kept out, gas is kept in and conductivity is virtually nonexistent.

Withstands Normal Bowing

The design of our Warm Edge Glazing System stands up to the bending and bowing that is natural in any glass unit.

Enhanced Noise Reduction

Our all-foam formula’s excellent sound-dampening properties reduce outside noise, even in industrial environments.

Is Less Condensation Important?

In winter, many people humidify their homes. If they didn’t, health and skin complexions would suffer. However, increasing humidity can cause window condensation.

Condensation can also be caused by traditional, highly- conductive metal spacers, leading to lower perimeter edge temperatures. As a result, negative consequences can occur such as:

  • Damaged wood, peeling paint and rotting frames
  • Looks unsightly
  • Can contribute to mold growth

The P-1 test is considered to be the world’s toughest durability test. All units are put into hot boxes and are continuously exposed to 140° F, 95-100% humidity and constant UV bombardment. Each week of testing is equivalent to one year of field use. Super Spacer is a registered trademark of Edgetech I.G. Inc.
