A new standard

Global Solarium introduces LE 3, the ultimate performance glass. It just might make all other Low-E glass obsolete. LE 3 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; LE 3 sets the new standard.

Low-E times three makes the difference

LE 3 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.

Energy savings all year long

The full-year benefits of LE 3 can be clearly seen. When the temperature soars in the summer, ordinary window glass just can't beat the heat. Moreover, tinted glass spoils the view. LE 3 is formulated to reject solar heat while maintaining attractive visibility. Therefore, it keeps the heat out while letting light in. As a matter of fact, LE 3 glass is our ultimate in performance.

What’s more, LE 3 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. During the cold weather, the insulating effect of your windows has a direct impact on how your rooms feel. The better insulated the glass; the warmer your room will feel. According the chart below, the insulating capability of LE 3 can't be compared to any other glass product. This is a key factor in the construction of comfortable sunrooms. Additionally, the dramatic comfort improvement in sunrooms 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.
