Energy Efficiency
You have likely heard the term “energy efficiency” before, but you might not be aware of how much having non-energy efficient windows can cost you throughout the year.
Energy-efficient windows from Window World are a wonderful investment for any home.

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-Factor measures the rate at which heat flows through an object. The lower your U-value, the less heat your windows allow through them.
R-Value determines how well the insulation inside your window performs. The higher your R-value, the better insulated your window is.
Window World of St. Louis 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.
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.
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 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.
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.
Here at Window World of St. Louis, we believe our customers should never have to sacrifice quality, comfortability or affordability. With our energy-efficient products, you can have it all.
