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.
