Built to Last
Fully rolled over, double-thick nail hem anchors panels to the wall; tested to withstand harsh weather.
Benefits of Energy Efficiency
In short, energy efficiency allows you to decrease the amount of energy you use—without sacrificing comfort. In warm months, energy-efficient products trap undesirable warm air outside. Alternatively, in cold months they wrap your home in a blanket of insulation, keeping your heat inside and protecting your interior from cold drafts. Energy-efficient products offer a myriad of benefits, both economically and environmentally.

Climate Requirements
Interested in Becoming ENERGY STAR® Certified?
ENERGY STAR is a government-sanctioned symbol for energy efficiency, credibility, sustainability and cost-savings for the consumer. Browse below to explore what’s required to become ENERGY STAR-certified and what it looks like in your region of the country.
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 Fort Wayne is located in ENERGY STAR’s Northern Climate category. To maintain certification here, our windows and doors must maintain a U-Value of ≤ .27 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. 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. 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
Window World’s innovative Intercept™ Warm Edge Spacer System features a unique, one-piece metal alloy, U-channel design which creates a protective and insulating thermal barrier to help reduce conducted heat and radiant heat transmittance through the window. The vacuum sealed, single-piece design makes Intercept™ spacers stronger and better at retaining insulating argon gas than many conventional design alternatives.
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.
