Benefits of Energy Efficiency
In short, energy efficiency allows you to decrease the amount of energy you use—without sacrificing comfort. Why switch to energy efficient products:
Save a significant amount of money every year
Trap undesirable warm air outside during warm months and wrap your home in a blanket of insulation during cold months
Allow fewer greenhouse gases to seep into the environment
Keep a home or commercial building much more comfortable during extreme weather conditions
Why Go Green
Energy-Efficient Products
Energy-Efficient Windows
Energy-Efficient Doors
Energy-Efficient Siding
Like a two-way mirror, energy-efficient windows allow visible light to pass through to keep your home well-lit, while reflecting long-wave infrared radiation to keep interior temperatures constant. Benefits include:
48% reduction in solar heat transfer during the summer months
104% increase in R-value of the glass in winter months
Protect your carpet, furniture and draperies from fading
The Intercept™ spacer system will extend the life of your windows
Window World carries a number of replacement doors that offer excellent energy efficiency. From choosing Low-E glass for a mostly glass patio door, to choosing an energy efficient Therma-Tru® entry door, your energy efficient options are nearly endless. A few added benefits, include:
Protection against unwanted temperature changes
A properly installed and sealed entry door
A durable and sturdy door that keeps your home secure
We find that many customers have never even considered vinyl siding as an energy efficient option. However, the Prodigy® Insulated Wall System from Window World takes vinyl siding to a whole new level with up to a 1.5 inch-thick foam insulation. A few added benefits, include:
Protection against unwanted temperature changes, no matter what season
Durable material that protects your home from hurricane-force winds, excessive moisture and hail

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 Muscle Shoals is located in ENERGY STAR’s South-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.
A warm-edge spacer system is just one way of increasing your window’s performance. SolarZone Low-E glass is an excellent option to help increase your home’s comfort and energy savings year-round. SolarZone Low-E glass is created by applying a microscopic, undetectable metallic coating to the second surface of an insulated glass unit. This coating helps to block heat gain in the summer while retaining furnace heat and allowing warm short wave solar rays in the winter.
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.
Make Your Home Energy-Efficient
When it comes to making your home energy-efficient, there is no risk. The payoff is significant and tangible. You will reap the benefits in comfort and cost, as energy-efficient products are an investment that pay for themselves time and time again.
