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.
The ENERGY STAR® Qualified SolarZone™ Insulated Glass Package Difference?
A window is 80% glass. The only way you’ll see substantial heating and cooling savings is to boost the glass performance. Window World of New Orleans helps you do that by combining UV-filtering Low-E glass (LG), insulating argon gas and the Intercept™ warm-edge spacer system to deliver superior energy efficiency. Combine, they can combat the harmful effects of the sun—no more worrying about faded carpets, curtains or furniture!
 In winter, a warmer glass temperature is maintained, increasing the R-value by an additional 104%. |
 In summer, a 48% reduction in solar heat gain helps cut air conditioning costs. |
An Inside Look
SolarZone™ Insulated Glass Package
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 keeps your home cooler in the summer.
- Low-E glass takes on a new duty in winter months. It lets warm solar rays into your home while blocking the heat in your home from getting out.
- Low-E glass keeps the heat from getting out in the winter.
How does the Intercept™ spacer system work?
- Its one-piece metal alloy, U-channel design creates an effective thermal barrier to help reduce conducted heat loss.
- Its sealed one-piece design makes it stronger and better at retaining insulating gas than many conventional designs.
How do Intercept™ spacers add to room comfort?
- They keep the edges of the window glass warmer, so your home feels more comfortable in winter.
- The temperature difference between the edge of an insulating glass unit with an ordinary spacer and one with an Intercept™ spacer system can be dramatic.
How do Intercept™ spacers help windows to last longer?
- LG 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.
What difference does Low-E glass make?
The window shown on the left is a clear insulated glass unit, and the window on the right is a Solarban® 60 Low-E insulated glass unit. Using thermography, you can clearly see the transmission of solar heat on the clear insulated glass window – indicated by the green, yellow and orange colors from the heat scale. When compared to the extremely low transmission of solar heat on the Solarban® 60 Low-E insulated glass unit, the best choice for your home is clear.

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 New Orleans is located in ENERGY STAR’s Southern Climate category. To maintain certification here, our windows and doors must maintain a U-Value of ≤ .40 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.
By adding Low-E glass to a standard insulating glass unit, you can improve the energy performance of your window year round by 24%.
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.
By adding the Intercept™ Warm Edge Spacer System, you can increase the efficiency by yet another 5%.
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.
By adding argon gas filling to the window, which is a better insulator than normal air, you can increase the efficiency by another 6%.
