We are always working to provide the most Energy Efficient windows on the market. Introducing LoE our new energy-saving surface coated glass. It offers more light transmittance and less reflectance than most glass options.

During the 1980’s the introduction of low-emissivity (low-e) coatings was revolutionary, they slowed the emission of radiant energy. 37 years later the original technology has been improved for the best energy efficiency results that consumers expect.

According to Jeff Sadr (CEO of Window City), this glass provides a remarkably high visible transmittance of 89% – significantly higher than standard pyrolytic hard-coat low-e glass. He described this as a “sputtered hard-coat,” with the “i” standing for indium. The coating is durable and it doesn’t have the bluish tint that some people object to with pyrolytic hard-coat low-e.

LoE-i89 is the new generation of low-e glass, outperforming the others all year round, especially during the cold Canadian winter months. This new coating will be found on the inside surface (room side) where it reflects the escaping heat back into the room, lowering U-factors and meeting the toughest energy guidelines as well. Coupled with our LoE 180 and argon fill, this double pane unit delivers near triple pane performance. What’s more, LoE-i89 enhanced performance glass is easy to clean and there is no haze to mar the view allowing more light to come into the room.

Benefits

• Best for frigid climates
• Keeps buildings naturally warmer in winter and reduces U-Values
• Meets strict Energy Efficiency guidelines
• Clearest surface without the haze
• Can be left single-glazed to keep costs down and performs even better as a double glazed unit
• Combines with other LoE options for the ultimate performance unit
• Comes standard with Neat self-cleaning technology
• Best fading protection
• Can meet the new proposed Energy Star guidelines throughout North America
• Turn your double-pane windows into triple-pane

When shopping for your new windows or if you are in the process of building a new home look out for i89 glass coating; this type of coating helps trap in heat, saves energy and maintains consistent indoor temperatures.
