Understanding Energy Efficiency

The Technology

Science Behind The Savings

Windows
Doors
Siding

Low-E Glass

Low-E glass is brilliantly engineered to minimize the amount of UV rays and unwanted temperatures into your home.

Warm-Edge Spacer

Intercept™ warm-edge spacer insulates the exterior edges of a sealed unit and can tack on 5% savings on monthly energy costs.

Vinyl Framing

Vinyl window frames are constructed with a complex array of compartments to help trap and repel unwanted weather.

Innovative Weatherstripping

Airtight weatherstripping seals the sides, top and bottom frames of your door to prevent air infiltration.

Insulated Core

Insulated polyurethane core provides an additional thermal barrier.

Sturdy Frames

Composite frames resist rotting, rusting and warping to withstand constant exposure to the elements.

Energy-Saving Door Lites

Decorative and ENERGY STAR-compliant door lites that allow light in but keep the elements out.

Insulated Structure

Built with rigid foam insulation to reduce energy loss and reinforce the siding for smoothness and straight lines.

Energy-Saving Barriers

High-density insulation to minimize outdoor noise for a quieter indoor ambiance and loss of wanted heat or air.

Built to Last

Fully rolled over, double-thick nail hem anchors panels to the wall; tested to withstand harsh weather.

 

Benefits of Energy Efficiency Products

Energy efficient products allow you to decrease the amount of energy your home uses—without sacrificing comfort. In fact, energy-efficient products increase comfort! Why should you switch to energy efficient products:

  • Save a significant amount of money on your energy bills every year
  • Keep warm air outside during warm months and wrap your home in a blanket of insulation during cold months
  • Fewer greenhouse gases released into the environment
  • Keep your 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:

  • U-Value of SolarZone Insulating Glass is 50% better than standard insulating glass.
  • 104% increase in R-value of the glass in winter months
  • U-Value of SolarZone Insulating Glass is 50% better than standard insulating glass
  • Protect your carpet, furniture and draperies from fading
  • The Intercept™ spacer system will extend the life of your windows

Explore 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

Explore Doors

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
  • Improved curb appeal and comfortability

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 Atlanta 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.

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.

The Intercept Spacer System features a unique, one-piece metal alloy, U-channel design that creates an effective thermal barrier to help reduce conducted heat loss through the window. Its sealed, one-piece design makes Intercept spacers stronger and better at retaining insulating gas than many conventional designs. The Intercept Spacer System is nearly 25% more effective than a traditional box-shaped spacer at the edge of the glass unit.

The optional Foam Spacer System is unique in its patented design. By combining a structural foam spacer with a seal of hot melt butyl to create a non-conductive edge, the non-metal Foam Spacer System eliminates any metal to glass contact, thereby increasing the edge of glass temperatures by over 16 degrees, which proves to be over 60% more energy-efficient than a traditional box-shaped spacer.

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.
