Energy Select 73

Safety-Ready Strength: This glass is engineered to be tempered quickly and easily, providing you with high-performance heat control in a reinforced safety glass for doors and large windows.

Worry-Free Maintenance: Unlike delicate coatings, it requires no specialized cleaners—you can clean your windows quickly and easily with standard household products without fear of damaging the finish.

Exceptional Clarity: It boasts a Visible Light Transmittance (VLT) of about 74%, meaning it lets in plenty of natural daylight without the heavy "blue" or "green" tints found in solar-control glasses.

Warm Glass Surfaces: By reflecting the home's long-wave infrared heat back into the room, it keeps the glass surface warmer to the touch, which eliminates the "drafty window" feeling in the winter.

Drastic U-Factor Improvement: By adding a second layer of Low-E to the room-side surface, you can improve the window’s insulating value by up to 20% compared to a standard double-pane unit.

Fits Standard Frames: Since the glass unit remains the standard thickness (usually 7/8" or 1"), you don't need specialized, wider "triple-pane" window frames.

Cost-Effective Efficiency: It provides a middle-ground price point for homeowners who want elite Energy Star® performance but don't want to pay the full premium for triple-pane glass.
