What is Low E Glass?

Low E glass, short for low emissivity glass, features a specialized metallic coating applied during its manufacturing process. This innovative coating serves a crucial function by reflecting heat back into the property, significantly improving thermal efficiency. As a result, properties utilizing low E glass experience enhanced comfort and reduced energy costs.

Measuring Performance with U-Values

The effectiveness of low E glass is often measured by its U-value, which indicates the rate of heat transfer. A lower U-value signifies better insulating properties, making low E glass a highly desirable option for energy-efficient homes. When combined with double glazing, the performance of low E glass is further enhanced, providing outstanding insulation properties.

Enhancements with Warm Edge Spacer Bars and Argon Gas

Typically, sealed units that incorporate low E glass also feature warm edge spacer bars and argon gas filling, which work together to elevate the overall performance. Warm edge spacers prevent thermal bridging, while the argon gas filling improves insulation by reducing heat transfer between the panes. This combination ensures that properties remain warm in winter and cool in summer, optimizing energy use and comfort.
