Near Triple-Pane Performance
It allows you to offer elite energy efficiency without the weight, thickness, or cost of a triple-pane window.
LoĒ-i89 Glass
Double Pane Solution For Triple Performance
LoĒ-i89 is a unique room-side coating that reflects escaping heat back into the room. When combined with other LoĒ coatings, it brings double-pane windows to triple-pane performance levels.
Boost Your Insulation
Why Choose LoĒ-i89?
Supercharged Insulation
-
- Lowers U-Factor: By reflecting heat back into the room, it can drop the center-of-glass U-factor from roughly 0.24 down to 0.20 (when paired with LoĒ-366 and Argon).
- Lighter & Thinner: You get the thermal benefits of triple-pane glass while using standard double-pane window frames and hardware.
- Easier Installation: Because the units aren't as heavy as triple-pane glass, they are easier for crews to handle and put less strain on the window's balance systems over time.
-
Enhanced Room-Side Comfort
Standard glass absorbs some of the room's heat and lets it leak outside, making the area near the window feel "chilly." i89 acts like a thermal mirror.
- Reflects Radiant Heat: It bounces the heat from your furnace or fireplace back into the room rather than letting it escape.
- Warm-to-the-Touch: The interior glass pane stays warmer, eliminating that "cold draft" feeling often felt in Ontario winters.
- ENERGY STAR® Compliance: It is a go-to solution for meeting the strict Northern Climate criteria for Energy Star 7.0 and IGMAC certifications.
-
Improved Clarity and Aesthetics
In the past, "room-side" coatings often had a blue tint or a hazy "milkiness." i89 was engineered specifically to be invisible.
- High Light Transmittance: It allows more natural light through than previous versions (like the old i81), with a visible light transmittance of approximately 89% in its monolithic form.
- No "Blue Hue": It lacks the distracting bluish tint common in older hard-coat Low-E products.
- Haze-Free View: It provides a crystal-clear look, ensuring the homeowner doesn't feel like they are looking through a film.
-
Durability and Ease of Maintenance
Since this coating is exposed to the inside of the home, it has to be much tougher than the coatings hidden inside a sealed unit.
- Scratch Resistant: It is a sputtered "hard-coat" that is as durable and scratch-resistant as the glass itself.
- Easy to Clean: You can use standard household glass cleaners (like Windex) without worrying about damaging the performance of the coating.
- Smooth Surface: Unlike some older coatings that felt "gritty," i89 is smooth, making it easy to wipe away fingerprints or label residue during the digital transformation of your assembly line.
