We’ve got your number.

Introducing LoĒ-i81™, the new Cardinal glass that takes center of glass U-factors to a remarkable 0.20 when coupled with our LoĒ²® or LoĒ³® glass and argon fill in a double-pane unit. Without argon and with or without capillary tubes, the unit still delivers a U-factor of just 0.23 – perfect for high altitudes. You get triple pane performance in a double-pane window. So take your window U-factors to a new low… with LoĒ-i81.

There’s no need to go to triple-pane windows to meet the various energy-saving guidelines. No need to invest in redesigning your windows and altering your manufacturing processes either. A double-pane IG unit with LoĒ-i81 can meet the guidelines.

Turn your double-pane windows into triple-pane performers.

LoĒ-i81 is sputtered onto the indoor lite, the #4 surface, thus reflecting escaping heat back into the room and lowering U-factors. Coupled with our LoĒ² or LoĒ³ glass and argon fill, this double-pane unit delivers performance much better than clear triple-pane – a center of glass U-factor of just 0.20 compared to 0.35 with clear triple-pane.

To surpass the U-factor performance of our LoĒ-i81 IG double-pane unit, you would need to go to a triple-pane unit with a low-E coating in each gap.

LoE-i81 Glass WindowsMeet today’s strictest energy efficiency guidelines.

With a center of glass U-factor of only 0.20 (0.23 without argon) and SHGC of just 0.25, an insulating glass unit with LoĒ³-366 and LoĒ-i81 meets the most stringent energy standards – without going to a triple-pane unit.

This allows you to offer more double-pane window options that can meet current ENERGY STAR guidelines everywhere in the country, including high altitudes, regardless of window size.

More double pane windows meet advanced requirements.

Federal tax credits in the United States require windows to be ENERGY STAR certified. LoĒ-i81 helps more configurations meet stringent U-factor requirements in the Northern zone without triple pane glazing. Use the interactive chart below to see how including LoĒ-i81 in your window designs makes the difference. See also: ENERGY STAR requirements for your location.

The advantages are more than clear.

In addition to providing maximum energy efficiency in a double-pane unit, LoĒ-i81 offers several other customer-pleasing benefits.

Its surface is smooth, making it easier to remove label residue and clean. And perhaps most importantly, there’s no haze to mar the view.

Cardinal IG units with LoĒ-i81 also incorporate our XL Edge® spacer, one of the reasons we have the industry’s lowest failure rate – only 0.20% over 20 years.

Give homeowners another reason to love LoĒ-i81 units – include Neat® naturally clean glass on the outside. Your windows stay cleaner longer and clean easier.

Finally, protect your windows in transit as well as on the job site with Preserve® protective film.
