Adds thermal protection
High-Performance Low-E4 glass employs a hermetically-sealed system for optimum insulation from heat, cold and sound. A patented low-conductivity spacer seperates the two panes of glass. The space between the two panes is filled with an argon gas blend to minimize the thermal transfer. Compared to ordinary dual-pane glass, High-Performance Low-E4 glass is 35% more energy-efficient in winter, 41% more efficient in summer.

Cuts energy bills up to 25%
Depending on where you live, that can cut your energy bills up to 25%*.
*A study of identical homes comparing Low-E to ordinary dual-pane glass showed a 25% savings on cooling bills, 10% on heating. Savings may vary geographically.

Reduces sound penetration
High-Performance Low-E4 glass reduces sound penetration significantly, when compared to single-pane glass. |
 |
Dries faster for easier cleaning
High-Performance Low-E4 glass features an invisible titanium dioxide (TiO2) coating, which makes cleaning easier. When this coating is activated by sunlight, dirt loosens from the glass and can be washed away by rain. |
 |
Reduces water spots up to 99%
The special TiO2 coating also makes the glass dry faster with up to 99% fewer water spots.**
**When activated by sunlight. |

Comes with a 20-year transferable, limited warranty
High-Performance Low-E4 glass is included in Eagle's 20/10 transferable limited warranty, giving you the confidence that your window will perform as specified. Your Eagle dealer can answer any specific questions you may have. |
 |
Protects glass with removable film
High-Performance Low-E4 glass is protected by a removable translucent film that shields it from damage and simplifies finishing. The film covers both the exterior and interior surfaces of the glass to help keep mortar, dirt and dust off the glass during shipping and construction. It also saves on the time it takes to mask the glass when painting or staining. |
 |
Filters UV rays
High-Performance Low-E4 glass works like sunblock to filter ultraviolet (UV) rays that can fade fabric and damage furniture. Ordinary dual-pane glass lets 63% of UV light pass through. High-Performance Low-E4 glass is layered with 11 microscopic coatings that cut UV transmission down to 17% with virtually no effect on the clarity or color of the light that enters your home. |
