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

In short, energy efficiency allows you to decrease the amount of energy you use—without sacrificing an amenity. 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.

Reasons to Go Green

  • Energy-efficient products save homeowners, businesses and large industries a significant amount of money every year.
  • Fewer greenhouse gases seep into the environment when you use energy-efficient heating and cooling systems, appliances and lighting products.
  • Energy-efficient windows and doors keep a home or commercial building much more comfortable during extreme weather conditions.

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 Rockford 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. 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.
