Low-E glass is brilliantly engineered to block most UV rays out so your home stays at a comfortable temperature each season.

2 iconWarm-Edge Spacer

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

3 iconVinyl Framing

Vinyl window frames are constructed to deliver excellent thermal insulation while sealing out drafts and unwanted weather.

1 iconInnovative Weatherstripping

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

2 iconInsulated Core

An insulated polyurethane core provides an additional thermal barrier for better insulation.

3 iconSturdy Frames

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

4 iconEnergy-Saving Door Lites

Decorative and ENERGY STAR-compliant door lites are an integral part in a door system’s seal and thermal performance.

1 iconInsulated Structure

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

2 iconEnergy-Saving Barriers

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

3 iconBuilt to Last

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


Benefits of Energy Efficiency

An energy-efficient home helps you reduce your carbon footprint without sacrificing an amenity. In warm months, energy-efficient products keep out unwanted warm air. Then in cold months, they help to insulate your home like a blanket, trapping the heat inside and protecting your interior from cold drafts. Energy-efficient products are great for you wallet, your comfort and the environment.

Energy Efficiency Adds Up

  • By adding Low-E glass to a standard insulating glass unit, you can improve the energy performance of your window year round by 24%.
  • Also, by adding argon gas filling to the window, which is a better insulator than normal air, you can increase the efficiency by another 6%.
  • And lastly, by adding the Intercept™ Warm Edge Spacer System, you can add yet another 5%!
  • That’s why your choice of ComfortWorld Windows with the SolarZone™ Insulated Glass Package is the most energy efficient window product on the market today!

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. Window World offers many ENERGY STAR® qualified glass packages. Explore the requirements to become ENERGY STAR-certified below and see 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 performs. 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 Kansas City is located in ENERGY STAR’s Northern 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.

How does Low-E Glass (LG) work?

  • Low-E glass filters long-wave radiation from the sun. This reduces solar heat gain from the sun in the summer, keeping your home cooler
  • Low-E glass takes on a new duty in winter months. It lets warm solar rays into your home while preventing the heat in your home from getting out.

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.

Low-E glass units expand and contract with temperature changes. In conventional insulating glass units, the sealant holding the unit together takes the stress of this flexing and can cause seal failure and insulating gas loss. In an Intercept™ LG. unit, the spacer flexes instead of the sealant, so it resists spacer movement and premature sealant failure.

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.
