U-Value
R-Value
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.
