In a quest for efficiency, window companies have taken The Path of Least Resistance, in making windows more efficient, by using more layers of Low-E coatings making Very Dark Windows that block out most of the light from your home and make it impossible to gain passive solar energy from the sun during the winter.
Because "Solar View" windows have excellent insulation properties and they allow passive solar energy from the sun to warm your home on those cold winter days they are the up to 67% More Energy Efficient* than typical Energy Star rated double-pane windows.
"Solar View" windows allow up to 68% More Visible Light* to pass through into your home than comparably performing triple-pane windows while still Blocking 71% of the Harmful UV rays. Making your home more inviting on those grey Portland winter days and saving you lighting costs year-round. Click here to see the data from our efficiency test results.
Cardinal Lo-i81™ provides excellent insulating capability, blocking heat loss to the outside and reflecting heat back into the room. What's more, it's an ideal glass for our climate and passive solar applications because it allows the winter sun's heat to pass into the home while still blocking 71 percent of the sun's harmful UV rays. Our Exclusive "Solar View Series" windows with Lo-i81™ technology will maximize your beautiful views and wonderful natural light saving you money all year long.
Cardinal Lo-i81™ is a state of the art coating baked onto the inside surface of the glass, (the one you can touch). This coating reflects escaping heat back into the room and significantly lowers U-factors. This Coating gives our State-of-the-Art double-pane windows U-factors rivaling many triple-pane windows. In addition to providing maximum energy efficiency in a double-pane unit, its surface is smooth, making it easier to clean. And perhaps most importantly, it is not a dark tinted window like most high performance and Triple-pane windows are.
XL Edge insulating glass comes with the lowest failure rate in the industry. Cardinal's superior IG construction translates into a 0.2% seal failure rate over twenty years - plainly the lowest in the industry. This is one of the reasons why cardinal is able to provide an additional, transferable, 20-year guarantee on XL Edge units. Argon is filled inside the IG unit, improving window U-factor. Since XL Edge is a warm-edge IG, the possibility of indoor condensation is greatly reduced
