Window World of Spartanburg
Low-E Energy Efficient Windows
Energy Efficient Low-E windows represent the latest technology in energy saving home improvement products and technology. Low-emittance (Low-E) coatings are extremely thin layers of metal, metal alloy, or metallic oxide covering the surface of the glass of a replacement window. These microscopic layers aid energy efficiency through a variety of means, including:
- Blocking heat/light/energy transmittance between sides of the coated glass
- Reflecting & blocking radiant heat transfer, preventing the air within your home from escaping, & the air outside from seeping in
- Minimizing solar heat gain transmittance between sides of the window glass
- Performing as exceptional insulation assistants in both warm & cool months
That is why the exclusive Window World SolarZone™ Glass Packages rely on the many energy performance characteristics of Low-E Glass. Although the climate is mostly warm in the Spartanburg areas, Low-E windows are designed to withstand both extremely high and extremely low temperatures, while preventing your home from losing excess cool/warm air to the outside extremes. The Low-E Solar Heat Transmittance value is just one of many ratings that Energy Star takes into consideration when rating and labeling replacement windows.
