Energy Savings with Energy Efficient Windows

Window World's new replacement windows provide substantial energy efficiency and savings for your home. We have saved money and energy for homeowners throughout the nation.

Warm-Edge Spacer System

A window's spacer system, or the component that separates glass layers, is remarkably impactful on the energy efficiency of the entire unit. The traditional, box-shaped spacer system can increase heat loss and cause condensation to form on the edge of the glass.

Our Warm-Edge Spacer is designed to block the path of escaping heat far more effectively, reducing condensation on winter glass. Non-conducive edges eliminate any glass-to-metal contact and contribute to a reduction of edge-of-glass temperatures. Featuring a unique U-channel design, these spacers are far more effective than their dated predecessors.

Low-E Glass

SolarZone Low-E Glass is created by applying a microscopic, undetectable metallic coating to the second surface of an insulating glass unit. Its intelligent design blocks heat gain from the sun's reflected rays in the summer, but allows warmth from shorter solar rays into the house during cold, winter months.

Argon

No detail is left to chance in our SolarZone Glass Packages. The space between the glass lites, historically just dead air, is filled with Argon gas. This colorless, odorless, non-reactive gas is the third most prevalent gas in our atmosphere. Its extremely low thermal conductivity and high density (Argon is 38% denser than air at 1.784 grams / liter at STP) makes it an ideal insulating agent.
