ENERGYSTAR® Qualified SolarZone™ Insulated Glass Package
What Makes the SolarZone™ Insulated Glass Package So Special?
The glass in your windows makes up 80% of the entire window system. Thus, upgrading to energy-efficient glass has a substantial effect on heating and cooling costs year-round. Complete with our UV-filtering Low-E glass, insulating Argon gas and Intercept™ Warm Edge Spacer System – ComfortWorld windows are engineered to improve comfort and combat harmful UV-rays.
![]() In winter, a warmer glass temperature is maintained, increasing the R-value by an additional 104%. | ![]() In summer, a 48% reduction in solar heat gain helps cut air conditioning costs. |
How does Low-E Glass (LG) work?
- Reduces long-wave radiation to keep your home cooler in summer months
- Allows solar rays into your home during the winter and blocks heat from escaping
How does the Intercept™ Spacer System work?
- One-piece metal alloy, U-channel design acts as a thermal barrier to reduce heat loss
- One-piece design is better equipped to contain insulating gas than traditional designs
- Helps keep glass surface much warmer than traditional spacer systems
- Expands and contracts with changing temperatures for increased durability and reduced sealant erosion

Thermography Right Before Your Eyes
The window on the left is a standard insulated glass unit. The one on the right is a SolarBan™ 60 unit with Low-E glass. Notice the increased heat gain on the traditional unit compared to the glass with Low-E insulated technology.
