What Does Low-E Stand For?
Low-E stands for Low Emissivity Coating—a special coating sealed inside the glass unit to enhance energy efficiency.
How Low-E Glass Works:
In Summer: Reduces the amount of direct heat entering through the glass, keeping your home cooler.
In Winter: Helps retain indoor heat by minimizing heat loss through the glass.
Benefits of Low-E Glass:
- Increases comfort by maintaining a more consistent indoor temperature
- Reduces energy costs by improving insulation year-round
- Blocks UV rays, helping to protect furniture, flooring, and décor from fading

Do I Need a New Window If My Glass Is Fogged?
No, you don’t need to replace the entire window—just the glass!
Fogged glass with moisture or water buildup inside the panes is a result of Seal Failure. This occurs when the seal between the glass panes breaks, allowing moisture to enter the airspace.
What Can You Do?
- Replace the glass instead of the whole window—saving time and money
- Restore clarity and insulation without the cost of a full replacement

Can I Apply Window Tint Film to My Glass?
While it may seem like a simple upgrade, applying window film to insulated glass can cause issues.
Why You Should Avoid It:
Voids Warranty – Most manufacturers do not cover insulated glass with applied tint film.
Heat Build-Up – The film can trap excessive heat, leading to seal failure and premature glass damage.
Better Alternative:
For tinted or Low-E insulated glass designed for energy efficiency and UV protection, call Empire Supply Co. at 314-645-2633 to explore the best options!
