Benefits of Energy Efficiency

Let’s face it. In extreme weather months like winter and summer, your energy bills can easily skyrocket – much to your dismay. While it may seem inevitable that this happens during these extremely hot or cold months, it doesn’t have to be. With energy-efficient windows from Window World of Lexington, you may be able to achieve significant savings on your energy bills over time. Because windows are made up of 80% glass, the effect that natural light has on a window is extensive.

  • Energy-efficient products save homeowners, businesses and large industries a significant amount of money every year.
  • When heating and cooling systems, appliances and lighting products can reduce the amount of energy they use, fewer greenhouse gases seep into the environment.
  • Some energy-efficient products, such as windows and doors keep a home or commercial building much more comfortable during extreme weather conditions.
  • Here at Window World, we believe our customers should never have to sacrifice quality, comfortability or affordability. With our energy-efficient products, you can have it all.

Your Climate

U-Factor Requirements

U-Factor measures the rate at which heat flows through an object. The lower your U-value, the less heat your windows allow through them.

  • Northern: ≤ .27
  • North-Central: ≤ .30
  • South-Central: ≤ .30
  • Southern: ≤ .40

R-Value Requirements

R-Value determines how well the insulation inside your window is performing. The higher your R-value, the better insulated your window is.

  • Northern: 13 – 21
  • North-Central: 13 – 21
  • South-Central: 13 – 21
  • Southern: 13 – 21

Why You Need A High-Performing Insulated Product

Window World of Lexington is located in Energy Star’s North-Central Climate category. To maintain certification here, our Windows and Doors must maintain a U-Value of ≤ .30 and an R-Factor from 13 to 21.


Glossary Of Terms

Energy Efficiency Terms You Need To Know

Low-E Glass

Low-E glass is a type of glass that has been treated with a microscopic, metallic coating designed to filter certain types of light into your home. The glass blocks heat gain from the sun’s reflected rays in warmer months and allows warmth from the sun’s shorter rays to flow into your home during cooler seasons.

Warm-Edge Spacer System

Our Intercept™ warm-edge spacer system is a new-age technology used to extend the shelf-life of window glass by reducing condensation build-up and edge-to-glass temperatures. Designed to seal in escaping heat, this spacer system is the most effective of its kind.

Argon Gas

Argon is a colorless, odorless and nonreactive insulating property with extremely high density and extremely low thermal conductivity, making it an ideal agent for year-round comfort.
