Quick Answer
Low-E (Low Emissivity) glass is window glass coated with a microscopic metallic layer that reflects heat while allowing natural light to pass through. It improves insulation, reduces UV damage, and increases energy efficiency.
How Does Low-E Glass Work?
Low-E coatings reflect infrared heat energy:
- Keeps heat out during summer
- Retains warmth during winter
- Reduces fading from UV rays
This makes it ideal for hot climates like Frisco, TX.
Low-E 366 vs Low-E 452: What’s the Difference?
Low-E 366
- 3 layers of silver coating
- Blocks approximately 95% of UV rays
- Excellent solar heat rejection
- Very popular in Texas homes
Low-E 452
- 4 layers of coating
- Blocks up to 99% of UV rays
- Designed to meet stricter International Building Code standards
- Maximum solar performance
Which Is Better for Frisco Homes?
In North Texas heat, most homeowners benefit from Low-E 366 or higher performance packages. The right option depends on window orientation and exposure.
