A new standard

Cardinal’s LoĒ³-366® glass (pronounced low E cubed-366) is the ultimate performance glass. It just might make all other low-E glasses obsolete. LoĒ³-366 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; LoĒ³-366 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 LoĒ² 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 LoĒ³-366.
