A New Standard
Cardinal introduces LoE³-366 (pronounced low E cubed-366), the ultimate performance glass. It just might make all other low-E glasses obsolete. LoE³-366 delivers the ideal balance of solar control and high visibility. And it provides the highest levels of year-round comfort and energy savings, making it the perfect glass no matter where you live. The secret? An unprecedented triple layer of silver. This is beyond ordinary low-E glass; LoE³-366 sets the new standard.
Low-E times three makes the difference
Cardinal has for years worked with top-tier window manufacturers by providing energy-efficient LoE² glass. Now with three layers of year-round thermal protection, the benefits are exceptional.
The result: a clear coating that blocks even more solar gain than ever before, reflects heat and lets the light stream in. Notice the difference below between clear glass, regular low-E glass and new LoE³-366.
Energy savings all year long
The full-year benefits of LoE³-366 can be clearly seen. When the temperature soars in the summer, ordinary window glass just can't beat the heat. And tinted glass spoils the view. LoE³-366 is formulated to reject solar heat while maintaining attractive visibility. So it keeps the heat out while letting light in. As a matter of fact, LoE³-366 glass is our ultimate in performance and clarity among all of Cardinal's clear coated products.
What is more, LoE³-366 provides the ultimate in fading protection. It blocks 95% of the sun's damaging ultraviolet rays - a leading cause of fading - so your furniture, carpets, curtains and wall coverings stay beautiful for years.
According to the chart below, the insulating capability of LoE³-366 can't be compared to any other glass product. This is a key factor in the construction of comfortable homes. Additionally, the dramatic comfort improvement in windows with warm glass surfaces means the humidity of the indoor air can be controlled and maintained properly. Proper humidity levels will improve comfort and promote a healthier living environment.
